'''Aadhaar''' is the ] of India. It is a 12-digit ] which can be verified online instantly. It is assigned to all residents of India for life-time on voluntary basis. It is not a proof of citizenship. It only guarantees identity; not rights, benefits or entitlements.
Aadhaar program is operated by the Unique Identification Authority of India (UIDAI), an authority of the ]. It was established in January 2009 under the ].<ref>{{cite web|url=http://uidai.gov.in/resource-center.html |title=Resource Center |publisher=UIDAI |accessdate=5 November 2013}}</ref> Aadhaar is expected to play the most prominent role in India Reforms from 2014 onwards.<ref name="india2">{{cite news|url=http://zeenews.india.com/business/news/economy/impact-of-aadhaar-gst-and-rail-dfc-to-be-significant-lasting-ubs_92748.html |title=Impact of Aadhaar, GST & rail DFC to be significant, lasting: UBS |publisher=Zeenews |date=16 January 2014}}</ref><ref name="indiatimes5">{{cite news|url=http://economictimes.indiatimes.com/news/economy/finance/subsidy-payout-via-aadhaar-accounts-can-save-1-2-per-cent-of-gdp-ubs/articleshow/28561792.cms |title=Subsidy payout via Aadhaar accounts can save 1.2 per cent of GDP: UBS|work=The Economic Times |accessdate=11 January 2014}}</ref>

==Overview==
UIDAI is the ] of ] i.e. it registers, assigns and verifies the ]. It is supposed to register two types of unique identities:<ref>{{cite web|url=http://uidai.gov.in/about-uidai.html |title=About |publisher=UIDAI |accessdate=31 October 2013}}</ref>
* Residents of India (called Aadhaar)
* Corporate entities (Corporate-UID) for company, bank, NGO, trust, political party etc.<ref name="uidai_a">{{cite web|url=http://uidai.gov.in/images/commdoc/other_doc/A_UID_Numbering_Scheme.pdf |title=A UID Numbering Scheme |author=Hemant Kanakia, Srikanth Nadhamuni, Sanjay Sarma |date=May 2010 |publisher=] |accessdate=31 October 2013}}</ref>

So far UIDAI has made progress on Aadhaar Number (AN) only. Work on Corporate-UID is yet to be published.

However, Corporate-UID has been provisioned within 12-digit UID number system.<ref name="uidai_a" /> Corporate-UID is supposed to produce the similar effect for corporate entities as Aadhaar does to a person i.e. identification and traceability of transactions. It is supposed to bring ] on financial transactions, donations; and to prevent corruption, ], ] (i.e. under a fictitious name), allocation of natural resources like land, ], mining of sand, iron-ore, coal-blocks, etc. Similar identifier ] (Business Identifier Code – BIC) exists for international business transactions (financial and non-financial).

UIDAI stores identities in its main ] called the Central Identity Data Repository (CIDR). Aadhaar identity is like internal passport to access various services in India. Aadhaar enrolment commenced in September 2010. Corporate-UID enrolment is yet to begin.

Aadhaar serves the purpose if Aadhaar-holder verbally tells the AN and it gets instantly verified online at the point of service, through KYC or E-KYC process in a paperless way; which provides high reliability of identity.<ref>^ "'Aadhaar' is a number, not an ID card: Montek Singh Ahluwalia". NDTV.com. 2 February 2013. Retrieved 31 October 2013.</ref> Only show of paper Aadhaar letter provides low reliability of identity as it can be easily faked.

National ID of India was first conceptualised and proposed by the Bhartiya Janata Party (BJP) before 1998 in view of illegal immigrants and effective distribution of social security benefits; i.e. prior to forming Government at the Center under NDA coalition in 1998. Now and then this topic is discussed by BJP/NDA.<ref>{{cite web|url=http://hindu.com/2002/04/12/stories/2002041203441100.htm |title=Multi-purpose identity cards soon: Advani |work=The Hindu |date=12 April 2002}}</ref><ref>http://books.google.co.in/books?id=z6xQgPV5tXEC&pg=PT813&lpg=PT813&dq=LK+Advani+on+National+ID&source=bl&ots=P45OMpaHm4&sig=RedpzeeTwZ4A9NATH0o28laN2hA&hl=en&sa=X&ei=PcMpU4r3HMK4rgerzIGoDQ&ved=0CHAQ6AEwCg#v=onepage&q=LK%20Advani%20on%20National%20ID&f=false</ref><ref>{{cite web|url=http://books.google.co.in/books?id=oPdNko4kq6wC&pg=PA87&lpg=PA87&dq=LK+Advani+on+National+ID&source=bl&ots=dEu5GEj1B1&sig=Be7nNJt7L7w5MdGtl3o39lUn_JU&hl=en&sa=X&ei=PcMpU4r3HMK4rgerzIGoDQ&ved=0CHMQ6AEwCw#v=onepage&q=LK%20Advani%20on%20National%20ID&f=false |title=Indian Identity Narratives and the Politics of Security – Gitika Commuri |date=9 September 1991}}</ref><ref>{{cite web|url=http://www.hindustantimes.com/india-news/newdelhi/bjp-promises-national-identity-card-for-all-indians/article1-396473.aspx |title=BJP promises National Identity Card for all Indians |work=Hindustan Times }}</ref>

==Properties of AN==
Aadhaar Number (AN) is a 12-digit ] assigned to residents of India for lifetime. Its format is 1234-5678-9012 where the 11-digits are used as a sequence and the rightmost 1-digit as an error detection ]. It is not a proof of citizenship. It only guarantees identity; not rights, benefits or entitlements. AN is a digital identity, instantly verifiable online at the point of service (PoS), at anytime, anywhere, in a paperless way.<ref name="uidai_a"/> It is assigned only to humans, not to corporate entities like companies or non-governmental organisations, unlike the ] card. The government expects that it will enable under-privileged people to access basic rights and social security benefits, which they have been deprived so far due to lack of identity.<ref name="uidai_b">{{cite web|url=http://uidai.gov.in/UID_PDF/Working_Papers/UIDandNREGA.pdf |title=UID and NREGA |publisher=] |accessdate=31 October 2013}}</ref>

AN is designed to enable government agencies to deliver retail public services securely based on ] data (], ] and face photo), along with ] (name, age, gender, address, parent/ spouse name, mobile phone number) of a person. AN is portable, free from limitations of physical presence of a person at a given place. Thus is can be used for casting vote from anywhere using mobile phone or personal computer, availing social security benefits from anywhere e.g. drawing PDS ration from any shop etc.

AN also works as a financial address, i.e. it works as a ] number. This is designed to help spread low cost, ubiquitous, ] services in rural areas – called micro-], as part of the Financial Inclusion initiative.<ref name="ref-1748936256">{{cite web|url=http://www.livemint.com/Opinion/X8jlZw47ytq9uXlPThz93M/Aadhar-bank-of-India.html|title=Aadhaar bank of India – Livemint|publisher=livemint.com}}</ref>

AN is valid all over India as a ], age and address. It is immensely helpful to migrant workers for employment and social security benefits. In case of change of personal information (mobile number, residence), the same can be updated with proof at Aadhaar Kendra, the permanent field-office.

AN is stored in a centralised database (CIDR) and linked to the basic demographics and biometric information – photograph, ten finger-prints and both iris – of each individual. It is verifiable online with the database server (CIDR) instantaneously, at a low cost. It is portable and robust enough to identify duplicate and fake identities from government and private databases. It is a randomly generated number, is sparsely populated in the database, designed not to be guessable, with no associated intelligence, and no profiling information such as ], creed, religion or language. Since Aadhaar uses 11-digit for sequence, therefore it has an ] of 10<sup>11</sup> (100&nbsp;billion). So AN can be assigned to 100&nbsp;billion residents, and is designed not to get used up in the next 500&nbsp;years. Upon the death of a person, the Aadhaar database record is marked as 'inactive', and is never reused nor deleted.<ref name="uidai_a" />

The de-duplication capability (uniqueness) of AN is theoretically 99.9% and practically 100% due to combination of multiple demographic and biometric attributes.

== Authentication of identities ==
The power of Aadhaar Number (AN) vests with its instant online ] at the point of service (PoS) with ] and ] attributes at anytime from anywhere in paperless way. No other ID in India has this feature.<ref name="economictimes.indiatimes">{{cite news|url=http://economictimes.indiatimes.com/news/politics-and-nation/uidai-makes-kyc-process-paperless-to-improve-customer-service/articleshow/21920514.cms |title=UIDAI makes KYC process paperless to improve customer service |work=] |date=19 August 2013 |accessdate=31 October 2013}}</ref><ref>{{cite web|url=http://www.business-standard.com/article/finance/rbi-validates-e-kyc-through-aadhaar-113090500007_1.html |title=RBI validates e-KYC through Aadhaar |work=Business Standard |date=5 September 2013 |accessdate=11 January 2014}}</ref> The ''point of service (PoS)'' means the service provider under license from UIDAI can verify Aadhaar identities online, unlike only passport office can verify passport and only RTO can verify driving license. It has dependence on minimum 2G internet access. Authentication devices and PoS will become ubiquitous by 2014.

It is designed to be secure, auditable, ], and consent-based (by biometrics or a ] (OTP)). OTP is sent by CIDR server to registered mobile phone number or email ID of the Aadhaar-holder. There are mainly 2 types of authentication with different combination of attributes:
* KYC: On consent, the service provider inputs the AN + Demographic data + Biometric or OTP, and receives 'Yes' or 'No' response from CIDR database server.
* E-KYC: On consent, the service provider inputs the AN + Biometric or OTP, and receives demographic data (photo, name, gender, address, date of birth, mobile number, email-id i.e. receives digital copy of the Aadhaar letter) from CIDR database server. Biometric data of resident is never shared by CIDR.<ref name="economictimes.indiatimes" />

The authentication data requested and received use ] communication from machine to machine through an ] (API) without human intervention. Following authentication, the received KYC data gets stored in the system of the service provider in the required data-format along with audit-track. Then this data is processed and service is provided to the customer immediately.<ref name="economictimes.indiatimes" />

The service provider decides what demographic and biometric attributes it wants to use for a given service. For example, iris and multiple fingers along with demographics may be used for high value transactions. Similarly, few demographic attributes with OTP only (no biometrics) may be used for low value transactions.

UIDAI does not support authentication requests thru paper letter, email or telephonic.

== Process comparison: Aadhaar, Passport and DL ==
Passport is an identity document recognised internationally to access various services like travel, employment, tourism etc. Aadhaar is considered as internal passport in India for identity and to access various services like travel, employment, tourism, attendance, LPG subsidy, PDS ration, scholarship, social security, pension, insurance, bank account, passport etc. The processes to obtain fresh Passport, Aadhaar and Driving License of almost all States have been compared in the following table. The table compares various data-points – Biometric, Demographic, Documents required and miscellaneous points.<ref>{{cite web|url=http://www.passportindia.gov.in/AppOnlineProject/welcomeLink |title=Passport Seva, Ministry of External Affairs, Government of India |publisher=Passportindia.gov.in }}</ref><ref>{{cite web|url=http://uidai.gov.in/aapka-aadhaar.html |title=Aapka Aadhaar |publisher=UIDAI }}</ref><ref>{{cite web|url=http://rto.kar.nic.in/ |title=Transport Department |publisher=Rto.kar.nic.in |date=28 September 2013}}</ref>

== Rationale and goals ==
To avail ] benefits as well as government-regulated services (e.g. bank account, insurance, mobile SIM, driving license, vehicle registration etc.); compliance to Know-Your-Customer (KYC) conditions are mandatory. The minimum KYC consists of 3 proofs:
* Proof of Identity (name with face photograph),
* Proof of Age (date of birth or estimated age),
* Proof of Residence (presently staying).

As of January 2014, India has population of 1.25&nbsp;billion, about 1&nbsp;billion mobile phones, 640,000 villages, 75% literacy, 2.5% (30&nbsp;million) income tax payer, 4% (50&nbsp;million) passport, 12% (150&nbsp;million) driving license, less than 20% (250&nbsp;million) bank account, 33% (400&nbsp;million) migrant labourers and 60% (750&nbsp;million) very poor people i.e. they live under Rs. 100 ($2) per day income and starve at least one meal everyday. About 80% (1&nbsp;billion) people do not hold identity documents to satisfy minimum KYC.<ref>{{cite news |url=http://timesofindia.indiatimes.com/india/Aadhaar-example-of-using-technology-to-leapfrog-Nandan-Nilekani/articleshow/24232069.cms |title=Aadhaar example of using technology to leapfrog: Nandan Nilekani |work=The Times of India |date=16 October 2013 |accessdate=11 January 2014}}</ref><ref>{{cite news|url=http://timesofindia.indiatimes.com/india/internal-migrants-make-up-1/3rd-of-Indias-population/articleshow/24313033.cms |title=Internal migrants make up 1/3rd of India's population|work=The Times of India|date=18 October 2013 |accessdate=11 January 2014}}</ref><ref name="slideshare.net">{{cite web|author=MongoDB |url=http://www.slideshare.net/regunathbalasubramanian/aadhaar-at-5thelephantv3 |title=Aadhaar at 5th_elephant_v3 |publisher=Slideshare.net |date=31 July 2012 |accessdate=11 January 2014}}</ref>

The Union Government spends Rs. 3,000&nbsp;billion ($50&nbsp;billion) on various social security subsidies (see table below 'Social security budget 2013–14'). In addition, various state governments also spend on specific social security programs. As per various estimates, about 40% to 85% of social security benefits have been plagued with fictitious and multiple identities due to lack of standard identity system that is verifiable instantly at the point of service.<ref name="slideshare.net"/><ref>{{cite news |url=http://economictimes.indiatimes.com/opinion/comments-analysis/ill-conceived-food-bill-has-too-many-inadequacies-that-will-prove-costly-for-india/articleshow/22134063.cms |title=Ill-conceived food bill has too many inadequacies that will prove costly for India|work=The Economic Times |date=29 August 2013 |accessdate=11 January 2014}}</ref>

=== Provide identity ===
Out of 1.25 billion (125 crore) population of India, over 1 billion (100 crore) do not hold identity documents to satisfy minimum KYC.<ref name="uidai">{{cite web|url=http://uidai.gov.in/UID_PDF/Front_Page_Articles/Events/AADHAAR_PDF.pdf |format=PDF |title=Aadhaar: Communicating To a Billion |publisher=UIDAI |date=7 May 2010 |accessdate=5 November 2013}}</ref><ref name=leapfrog>{{cite news|url=http://timesofindia.indiatimes.com/india/Aadhaar-example-of-using-technology-to-leapfrog-Nandan-Nilekani/articleshow/24232069.cms |title=Aadhaar example of using technology to leapfrog: Nandan Nilekani|work=The Times of India |date=16 October 2013 |accessdate=31 October 2013}}</ref><ref name="timesofindia.indiatimes.com">{{cite web |url=http://timesofindia.indiatimes.com/home/opinion/edit-page/Aadhaar-uses-technology-to-give-a-face-to-the-poor-and-deserves-our-support/articleshow/31964297.cms |title=Aadhaar uses technology to give a face to the poor and deserves our support|work=The Times of India |date=14 March 2014}}</ref>

There are over 400 million (40 crore) migrant labourers (internal) who are poor, landless, not educated or illiterate. These migrant workers do not exist on the government's databases, despite having worked for years in another district of the same state or another state of India. Lack of identity prevents them from basic rights and social security benefits.<ref name="leapfrog" /><ref name="indiatimes2"/>

The prime objective of Aadhaar is to provide lifetime ] which is verifiable instantly online at the point of service with biometrics in paperless way.<ref name="leapfrog" />

=== Provide social security benefits ===
Aadhaar-platform is aimed at providing ] benefits / ] based on eligibility thru direct benefit transfer. It provides access and options to rural and poor people. It helps bring transparency and eliminate corruption, leakage and inefficiency.<ref name="articles.timesofindia.indiatimes.com"/>

The following table shows financial size of the social security benefits / ] funded by the Union government of India. The table does not cover other programs operated by various State governments, see ]. The social security benefits / subsidies offered by various state governments is estimated to be above Rs. 600&nbsp;billion (US$10&nbsp;billion). Thus total subsidies become Rs. 3,600&nbsp;billion (US$60&nbsp;billion).<ref>{{cite web|url=http://www.moneycontrol.com/news/economy/budget-2013-food-security-gets-rs-10kcr-fy14-subsidy-at-rs-231lk-cr_832058.html |title=Budget 2013: Food Security gets Rs 10Kcr; FY14 subsidy at Rs 2.31lk-cr |publisher=Moneycontrol.com |accessdate=11 January 2014}}</ref><ref name="ref-815228967">{{cite news|url=http://www.firstpost.com/economy/budget-2013-rural-development-gets-46-hike-rs-33000-cr-for-mgnregs-643294.html|title=Budget 2013: Rural development gets 46% hike, Rs 33,000 cr for MGNREGS |publisher=Firstpost (now Firstbiz)|accessdate=9 February 2014|archiveurl=http://web.archive.org/web/20140228004916/http://www.firstbiz.com/economy/budget-2013-rural-development-gets-46-hike-rs-33000-cr-for-mgnregs-37226.html|archivedate=28 February 2014}}</ref>

=== Financial inclusion ===
] has planned Aadhaar-linked bank accounts for all adults of India by January 2016 to meet its commitment on Financial Inclusion. It will greatly transform India by preventing the poor people falling into debt-traps of unlawful money-lenders, cashless transactions, elimination of poverty and corruption.<ref name="indianexpress" /><ref name="ref-1748936256"/><ref>{{cite news|date=11 January 2014 |url=http://www.business-standard.com/article/finance/aadhaar-makes-our-deadline-practical-mor-114011001192_1.html |title=Aadhaar makes our deadline practical: Mor |work=Business Standard |accessdate=11 January 2014}}</ref>

Basic Aadhaar-enabled Bank Account (AeBA) is a ''Basic'' savings account (zero-balance) where a Debit-card is issued and Aadhaar number is used as the account number. It can be instantly opened (like prepaid bankcard). Transactions operate with fingerprint authentication only; as indicated by Aadhaar-logo on the card. ] is not issued to zero-balance AeBA because it is aimed at financial inclusion of unbanked, illiterate and rural people. Bankcard operates at micro-] and other ATMs equipped with fingerprint scanner. Presently ] is not issued to these accounts due to infrastructure problem. Transactions like deposit, withdrawal, transfer, balance-check can be performed.

Generally, a micro-ATM consists of a laptop computer or smart-phone equipped with 2G-internet, fingerprint scanner, receipt-printer, speaker and power backup (solar / battery). It is human-operated by commission agent called Banking Correspondent (BC) so that illiterate customers do not face problems of ATM machine operations. BCs are generally chemist-shops, provision shops or mobile-vans. It is similar to the commission agent model of prepaid mobile phone recharge.<ref name="iba.org.in">http://www.iba.org.in/upload/MicroATM_Standards_v1.5.1_Clean.pdf</ref>

Once bankcards become common in rural areas, then whole India will become a nation of cashless-transactions like USA with higher transparency and accountability. Cash is used for bribery and corruption.<ref name="economictimes.indiatimes_b" />

Once rural and poor people get the bank account then they become eligible to avail bank loans for farming and domestic purpose at 10% per year interest rate. It would be a great transformation of rural and poor India. Currently village money-lenders lend at usury rates (10% to 30% per month i.e. 120% to 360% per year) which results into many social evils. The related social evils are debt-trap, bonded-labour for generations, poor become landless, homeless destitute and children get deprived of education as they become bonded-labourer, families get shattered and many farmers commit suicide every year due to impractical, blood-sucking loan-interest burden. Thus financial inclusion will put stop to unlawful, blood-sucking money-lending business and the associated social evils.<ref name="ref1002772023">{{cite news|url=http://www.business-standard.com/article/finance/moneylenders-back-in-ap-with-jumbo-lending-rates-112080400039_1.html|title=Moneylenders back in AP with jumbo lending rates|work=Business Standard}}</ref><ref name="ref930753352">{{cite news|url=http://www.newindianexpress.com/states/andhra_pradesh/14-farmers-commit-suicide-in-25-days/2013/08/26/article1752285.ece|title=14 farmers commit suicide in 25 days|work=The New Indian Express}}</ref><ref name="ref1606964464">{{cite news|url=http://articles.timesofindia.indiatimes.com/2013-06-30/hyderabad/40286009_1_farm-suicides-120-farmers-mahbubnagar|title=Farm suicides on the rise|work=The Times of India}}</ref>

India is not the first country to implement the banking service for rural and under-privileged. It is being implemented after studying various banking systems in the world which have been successfully operational for the past several decades.

===Aadhaar-DBT===
Aadhaar-Direct Benefit Transfer (DBT) is an Aadhaar-enabled financial service used for direct payment of social security benefits into the bank account of the Aadhaar-holder.<ref>{{cite web|url=http://finmin.nic.in/reports/Report_Task_Force_Aadhaar_PaymentInfra.pdf |title=Report on the Task Force on an Aadhaar-Enabled Unified Payment Infrastructure |publisher=Finmin.nic.in |accessdate=6 November 2013}}</ref><ref>{{cite news|author=Jaideep Deogharia |url=http://timesofindia.indiatimes.com/city/ranchi/Chief-secretary-orders-probe-into-Aadhaar-discrepancies/articleshow/29051868.cms?cfmid=14000000 |title=Chief secretary orders probe into Aadhaar discrepancies |work=The Times of India |date=19 January 2014}}</ref>

A pre-existing or new bank account can be enabled as AeBA by seeding (linking) it with Aadhaar number.
Seeding makes mapping information stored onto ] payment-gateway, that facilitates the subsidy payment. The seeding helps identify the genuine and eligible beneficiary, and prevents duplicate and non-existent (fake, dead) persons.<ref>{{cite web|url=http://www.npci.org.in/aboutus.aspx |title=About Us |publisher=] |accessdate=4 November 2013}}</ref> One can link bank account as self-service option thru ATM kiosk, Internet, bank website, telephone or by providing a copy of the Aadhaar letter to bank. Bank links the account with Aadhaar number after online verification thru RASF (Remote Aadhaar Sharing Framework link).<ref>{{cite web|author=Reshma Ravishanker |url=http://www.deccanherald.com/content/391397/banks-link-aadhaar-numbers-account.html |title=Banks link Aadhaar numbers to account through ATM |work=Deccan Herald |date=11 March 2014}}</ref>

Eligibility of beneficiary is applied based on rules and is cross-checked with other related databases which are also Aadhaar-linked. This approach is designed to improve the ], add efficiency; prevent corruption, middlemen and delayed payments; eliminate non-existent, duplicate and ineligible beneficiaries. It results in direct benefit access to the eligible people; and saves multi-billion rupee from corruption annually.<ref>{{cite news|url=http://articles.timesofindia.indiatimes.com/2013-07-21/mumbai/40708660_1_bogus-ration-cards-two-crore-cards-bureaucrat |title=Officials to be booked for 12L fake ration cards |work=The Times of India |date=21 July 2013 |accessdate=4 November 2013}}</ref><ref>{{cite news|url=http://ibnlive.in.com/news/over-13-lakh-fake-old-age-pension-beneficiaries/158135-60-118.html |title=Over 13 lakh fake old age pension beneficiaries |publisher=] |accessdate=4 November 2013}}</ref>

Tangible benefits become visible from 2014. A report of UBS Securities published in Jan 2014 shows that Aadhaar-DBT can save 1.2% of GDP. GDP of India is $1,800 billion, thus the saving is $22 billion (Rs. 1.32 trillion), which ultimately translates to 33% savings on overall social security spending.<ref name="indiatimes5"/>

Finance Minister informed the Parliament during Vote on Account that as of 31 January 2014, under DBT Rs. 33 billion for 21 million LPG subsidy and Rs. 6.28 billion (628 crore) have been transferred for various social programs in 5.4 million transactions.<ref>{{cite web |url=http://articles.economictimes.indiatimes.com/2014-02-18/news/47413178_1_aadhaar-lpg-beneficiaries |title=Vote on Account 2014: Govt committed to Aadhaar; Rs 3,370 cr transferred to LPG beneficiaries|work=The Economic Times }}</ref><ref>{{cite web|author=Sujay Mehdudia |url=http://www.thehindu.com/news/national/government-fully-committed-to-aadhaar/article5699113.ece |title=Government fully committed to Aadhaar |work=The Hindu |date=17 February 2014}}</ref>

===e-governance===
Another objectives of Aadhaar Number (AN) is to use it as an effective governance tool – to bring transparency, efficiency and weed out the bogus beneficiaries from social security programs e.g. social security pensions, scholarships, public health, NREGA, subsidy on PDS Ration, Kerosene, LPG etc. Thus Aadhaar is expected to save public exchequer from bogus beneficiaries up to Rs. 1.1&nbsp;Trillion (Rs. 1100&nbsp;billion) by the year 2020 as per study report of National Institute of Public Finance and Planning.

In 1980s pointing towards the widespread corruption in social security programs in India, the then Prime Minister ] had made a famous statement in Parliament that only 15% of benefits reach the poor people; the remaining 85% are eaten-away by the corrupt officials and middlemen.<ref name="foodbill">{{cite news|url=http://economictimes.indiatimes.com/opinion/comments-analysis/ill-conceived-food-bill-has-too-manyinadequacies-that-will-prove-costly-for-india/articleshow/22134063.cms |title=Ill-conceived food bill has too many inadequacies that will prove costly for India |work= The Economic Times |date=29 August 2013 |accessdate=31 October 2013}}</ref> Similarly, the ] Chief said that Aadhaar will help eradicate poverty in India.<ref name="ndtv">{{cite web|url=http://www.ndtv.com/article/india/aadhaar-to-help-eradicate-poverty-says-world-bank-chief-364598 |title=Aadhaar to help eradicate poverty, says World Bank chief |publisher=NDTV.com |date=9 May 2013 |accessdate=31 October 2013}}</ref>

The stand-alone databases of social security services can not interact with each other due to lack of a ] like AN. Thus stand-alone databases do not have ability to detect and prevent fictitious and ineligible beneficiaries. Therefore, AN is aimed at eliminating retail corruption in the public domain which has affected social security programs since independence. In India, about 750&nbsp;million (60%) people starve everyday for at least one meal.<ref name="slideshare.net"/><ref name="kerosene" />

===Prevention of corruption===
Although Aadhaar can prevent retail-corruption to much extent, yet it is not capable of preventing wholesale-corruption like allocation of coal-blocks, 2G spectrum, mining of iron-ore, sand, onion hoarding etc. Corporate-UID is required to prevent such wholesale-corruptions and this provision is already inbuilt in UIDAI Number System, yet implementation is pending.<ref>{{cite web|url=http://www.youtube.com/watch?v=mgELSndZ8jM |title=Anna's protest unjustified: Nandan Nilekani |publisher=YouTube |date=18 August 2011 |accessdate=31 October 2013}}</ref><ref>{{cite web|url=http://www.youtube.com/watch?v=uvos3tkRT5Q |title=Face the Nation – FTN: We can't fight corruption through OB Vans, says Nandan Nilekani |publisher=YouTube |accessdate=31 October 2013}}</ref>

===Prevention of identity fraud===
]s such as ] (using the identity of another person, dead or alive) and ] (fake IDs created on fictitious person, also called ''benami'') has been a common practice in India. The scan, super-imposition and color-print functions of ubiquitous printers have made paper-based and plastic card-based frauds much easy. Identity fraud is committed for financial gain or due to compulsion. Identity fraud committed for financial gains are mostly ''benami'' companies and ''benami'' bank accounts used for bribery and money laundering. Identity fraud committed on compulsions is either due to lack of a person's own ID documents, or due to the intention of not using one's own ID.<ref name="mid-day.com">{{cite news|url=http://www.mid-day.com/news/2011/jul/170711-fake-document-racket-PAN-card-sellers.htm |title=Fake PAN card seller gang busted |work=] |date=17 July 2011 |accessdate=5 November 2013}}</ref><ref name="indiatimes1">{{cite news|url=http://articles.timesofindia.indiatimes.com/2010-06-03/mumbai/28297149_1_sim-card-documents-bag |title=No papers for SIM card?

Since they normally stay in shared shanties without any valid documents, they cannot produce PoR. So they fraudulently purchase available IDs of other persons at a high price to obtain a mobile SIM.
Prisoners, criminals and terrorists never procure mobile SIMs using their own IDs due to obvious reasons of getting tracked.<ref name="indiatimes1"/><ref>{{cite news|url=http://timesofindia.indiatimes.com/city/delhi/Trio-arrested-for-SIM-card-fraud/articleshow/24449852.cms |title=Trio arrested for SIM card fraud |work=The Times of India |date=20 October 2013 |accessdate=4 November 2013}}</ref>

The employees of TSPs are generally under pressure to achieve sales targets. Hence there are cases where one set of IDs submitted by a genuine customer to procure just one SIM has been reused 100 times to issue 100 SIMs fraudulently.<ref name="indiatimes1"/>

===Ghost employees===
Thousands of fictitious employees are found on payrolls of government and public sectors each year. In 2013–14, 29,000 ghost employees of Jammu and Kashmir government have been detected, 1,588 of Municipal Corporation of Delhi and 400 of Air India including some ghost pilots have been detected.

== Existing IDs and problem areas ==
Traditionally existing IDs in India have been token-based i.e. paper and plastic-based driving license, passport, PAN card, voter ID etc. None of these IDs have the feature of being lifetime digital identity that can be verified instantly in public domain at anytime anywhere for uniqueness and real existence. Moreover, as of 2013, only 150&nbsp;million hold driving license, 50&nbsp;million people hold passport and 30&nbsp;million pay taxes, and these are mutually inclusive.<ref name="leapfrog"/> These IDs do not qualify the generic all-purpose ID for life. These IDs expire at certain intervals, for various reasons, and need to be re-applied with payment for fresh-issuance or renewal. The identification number on these IDs changes with each renewal. Some IDs are not accepted across states, and people are asked to provide local ID. These IDs (except voter ID) are generally possessed by urban higher-income group. The rural and poor, who are largest number, do not possess it. Hence these do not serve the purpose of providing minimum KYC to a billion people. Others do have some ID yet not sufficient for minimum KYC. Women and children of well-to-do families in rural and tribal areas also generally lack KYC IDs.

Traditional IDs are not biometric based. Moreover, these plastic or paper-based IDs are easily reproducible with modified and fake information (such as by scan, super-imposition and print functions of ubiquitous printers). Thus these easily lead to identity theft and identity fraud.

Photocopies of IDs of various people are taken fraudulently or stolen from various places (e.g. photocopy shops, employment applications), then multiple copies are made and sold to needy people at high price. Since very large number of people in India do not hold minimum KYC IDs, therefore they buy such identity-theft papers to procure mobile SIM. At least 100&nbsp;million mobile SIMs in India, currently in use, have been procured on identity-theft and identity-fraud.<ref name="mid-day.com"/>

Therefore, there has been a need to provide instantly verifiable identity to all residents of India.

==Enrollment==

===Process===
Process is almost similar to obtaining a fresh passport. Enrollment is voluntary and free of cost. When a person desires to obtain Aadhaar identity, he or she has to submit a prescribed enrolment form attached with minimum KYC documents (i.e. proof of identity, age, residence) to a UIDAI appointed registrar. If, for example, a person from a village does not have KYC IDs, then a recognised Introducer (generally a ]) can introduce and certify his or her PoI, PoA and PoR. Introducers are appointed by UIDAI based on certain criteria and conditions.

On completion of paper formalities, the biometric scanning (2 iris, 10 fingers, facial photo) is done by the operator and a printed acknowledgement is given to the applicant. Then scanned data, along with the application form, is sent to appropriate authorities for verification and final processing. It takes about three months to get an Aadhaar number on successful processing.<ref name="myaadhaarcard1">{{cite web|url=http://www.myaadhaarcard.in/aadhaar-news/india-post-admits-laxity-in-aadhaar-delivery/ |title=India Post admits laxity in Aadhaar delivery &#124; My Aadhaar Card |publisher=Myaadhaarcard.in |accessdate=4 November 2013}}</ref><ref>{{cite web|url=http://www.rtifoundationofindia.com/delay-delivery-aadhaar-card-if-uidai-not-aware-sta |title=Delay in delivery of Aadhaar Card – If UIDAI is not aware of the status after dispatch of the card they should transfer the application to Department of Post rather than giving an evasive reply |publisher=RTI Foundation of India |accessdate=4 November 2013}}</ref><ref>{{cite news|url=http://www.hindustantimes.com/india-news/newdelhi/govt-cracks-the-whip-on-firms-behind-delay-in-delivery-of-aadhar-cards/article1-1040585.aspx |title=Government cracks the whip on firms behind delay in delivery of Aadhar cards |work=Hindustan Times |accessdate=4 November 2013}}</ref>

As self-service, it is faster to download the "E-Aadhaar" letter (pdf copy) from the UIDAI portal after 3&nbsp;months than await the postal delivery of Aadhaar letter, which may take 6 to 9&nbsp;months presently.<ref name="indiatimes3">{{cite web|url=http://articles.timesofindia.indiatimes.com/2013-05-29/bangalore/39600583_1_aadhaar-card-enrolment-unique-identity-card |title=UID not delivered? Take a print of your e-Aadhaar |work=The Times of India |date=29 May 2013 |accessdate=4 November 2013}}</ref>

===UIDAI versus NPR===
UIDAI has been mandated to enroll 600&nbsp;million people in its assigned territory. Similarly, the Census Operations group (under the ]) has been mandated to enroll the remaining 650&nbsp;million people in its assigned territory under the ] (NPR) program. Although an enrolment of 650&nbsp;million is done by Census Operations, the collected data is given to the UIDAI for generation of Aadhaar numbers. Thus UIDAI generates Aadhaar numbers for the whole of India.

UIDAI has no role to play in management of NPR enrolment centres.<ref name="thehindubusinessline">{{cite news|author=Sravanthi C |url=http://www.thehindubusinessline.com/blogs/blog-sravanthic/the-scene-at-an-aadhaar-camp/article5280444.ece |title=People-watching at an Aadhaar camp |work=The Hindu |date=24 October 2013 |accessdate=1 November 2013}}</ref>

The UIDAI territory for enrolment includes ], ], ], ], ], ], ], ], ], ] and ], etc. The Census Operations territory for enrolment includes ], ], ], ], ] and ], etc.

As of October 2013, a large volume of scanned biometric data have been rejected by UIDAI due to poor quality, thus causing delays and inconvenience to the public.<ref name="thehindubusinessline" />

===Status of AN generation===
The total number of Aadhaar enrolment as of March 2014 is over 750 million (75.0 crore) and is going at the rate of about 1 million per day. The total number of Aadhaar Number (AN) processed and assigned as of 21 March 2014 is over 606 million (60.6 crore). <ref>{{cite web |url=http://articles.economictimes.indiatimes.com/2014-03-11/news/48118153_1_aadhaar-project-uid-project-nilekani |title=Every second Indian now has Aadhaar number|work=The Economic Times |date=11 March 2014}}</ref>

=== Pending bill ===
The Union cabinet headed by the ] has cleared the UIDAI Bill on 8 October 2013. It was expected to be tabled in Parliament by the UPA-2 government. However, UPA-2 could not table it. Now, the next government will table this bill in the Parliament.<ref>{{cite news|author=Mahendra Singh |url=http://timesofindia.indiatimes.com/india/Cabinet-okays-bill-giving-legal-backing-to-UIDAI/articleshow/23766628.cms |title=Cabinet okays bill giving legal backing to UIDAI |work=] |date=9 October 2013 |accessdate=31 October 2013}}</ref><ref>{{cite news|url=http://economictimes.indiatimes.com/news/politics-and-nation/cabinet-approves-bill-to-give-uidai-statutorystatus/articleshow/23710592.cms |title=Cabinet approves bill to give UIDAI statutory status |work=] |date=8 October 2013 |accessdate=31 October 2013}}</ref>

However, the government maintained that it does not deny public services such as LPG at market rate (i.e. non-subsidized). However, Aadhaar will continue to be mandatory for receiving social security benefits like subsidy on LPG. Those who do not want social security benefits can continue without Aadhaar.

=== Politically-motivated opposition ===
Some politically motivated people have been opposing Aadhaar. These people ignore socio-economic benefits brought by the technological marvels of instant and accurate verification of identity. They seem to oppose it just for the sake of electoral benefits rather than better governance and development of Indian society. In addition, the beneficiaries of corruption are naturally opposed to it.<ref name="timesofindia.indiatimes.com"/>

===Privacy concerns===
To obtain fresh Indian passport, one has to provide biometric data (face-photo, 10 fingerprint, identification mark on body, but no iris image) as well as demographic data (proof of identity, age, residence, education level, 2 references from neighbourhood, pending criminal cases) with fee. Passport is issued with an embedded electronic chip for contactless communication and tracking whereas Aadhaar letter is issued on simple paper and pdf soft-copy. Similarly, Driving License of almost all States requires biometric data, education certificate and medical test report (blood group, disease details, vision, height, weight etc.). DL is also issued on chip-based smart card. See the comparison table 'Process comparison: Aadhaar, Passport and DL' in the above paragraph.<ref name="timesofindia.indiatimes.com"/><ref>{{cite web|url=http://www.passportindia.gov.in/AppOnlineProject/online/faqApplicationForm |title=Application Form Overview : FAQ : User Assistance &#124; Passport Seva |publisher=Passportindia.gov.in }}</ref>

Aadhaar registration collects biometric data (face-photo, 10 fingerprint, 2 iris image, but no identification mark on body) and bare minimum demographic data (proof of identity, age, residence) through enrolment form and documentary proof. Peruse the Enrollment-Form with data fields on page-1 and instructions on page-2.<ref>https://nsdl.co.in/downloadables/pdf/Aadhaar-Enrolment-Form_English.pdf</ref> Blood group and profiling information like religion, caste, income, property-holding, education etc. are not collected.<ref>{{cite web|agency=Press Trust of India |url=http://articles.economictimes.indiatimes.com/2011-02-25/news/28634033_1_privacy-fears-uidai-chairman-nandan-nilekani-aadhar |title=Nilekani seeks to allay privacy fears surrounding 'Aadhar'|work=The Economic Times |date=25 February 2011 |accessdate=11 January 2014}}</ref> Thus Aadhaar collects lesser demographic data and one different biometric data (iris-image in lieu of body identification mark) in comparison to passport.

Privacy issues and risks equally apply to information and data (with or without biometrics) provided by people to census office, tax office, passport office, driving license, vehicle registration, land and building registration, registration of birth, marriage and death, employers (current, past and prospective), banks, credit card companies, insurance companies, telephone service provider, television service provider, internet service provider, internet services (email, video, social media, search engine, chat, voice, file-storage and transfer etc.), registration at school/college, post-office and courier services, hospital registration and medical records, visa of US and UK etc. Various visa to Indians of US, UK and other countries need much more data – blood group, fingerprint, height, weight, medical exam, income details, property-holding, parents date of birth and many other details<ref name="thehindubusinessline1">{{cite news|author=A.

In India, government departments, public and private sectors have been using biometrics (fingerprints and face photo) for years, decades and centuries in some or all offices. Examples of fingerprints usage are: Land and building registration (since British era), Defense departments (fingerprints as service record of civilian as well as service personnel since British era till now, now also used for access and attendance), Planning Commission of India (for access and attendance), census office (for compulsory NPR), Passport, RTO (for driving license), insurance companies, IT, BPO and healthcare companies (for access and attendance), visa of US and UK etc.<ref>{{cite web|url=http://simplybanking.wordpress.com/2013/08/17/indian-planning-commission-launches-aadhaar-based-attendance-system/ |title=Indian Planning Commission launches Aadhaar based attendance system &#124; Simple Financial Mantras |publisher=Simplybanking.wordpress.com |date=17 August 2013 |accessdate=11 January 2014}}</ref><ref>{{cite web|url=http://www.path2usa.com/fingerprinting-and-biometrics-for-us-visa |title=Fingerprinting and Biometrics for US Visa |publisher=Path2usa.com |date=24 December 2013 |accessdate=11 January 2014}}</ref><ref>{{cite web|url=http://www.ixpvisas.com/uk-introduces-new-biometric-visas-for-indians- |title=UK Introduces New Biometric Visas for Indians |publisher=Ixpvisas.com |date=18 December 2007 |accessdate=11 January 2014}}</ref><ref>{{cite web|url=http://www.translineindia.com/defense-amp-homeland-security-category-33.htm |title=Welcome to Transline Technologies |publisher=Translineindia.com |accessdate=11 January 2014}}</ref><ref>{{cite news|url=http://www.indianexpress.com/news/compulsory-biometric-attendance-system-fails-to-take-off/1152178/ |title=Compulsory biometric attendance system fails to take off |work=The Indian Express |date=7 August 2013}}</ref><ref>{{cite web|url=http://passportindia.gov.in/AppOnlineProject/online/knowPassportSeva |title=Passport Seva : About Us &#124; Passport Seva |publisher=Passportindia.gov.in |date=29 July 2013}}</ref><ref>{{cite web|url=http://ditnpr.nic.in/ |title=National Population Register-Home |publisher=Ditnpr.nic.in |accessdate=11 January 2014}}</ref><ref>{{cite web|url=http://articles.economictimes.indiatimes.com/2013-06-21/news/40119535_1_sim-neeraj-kumar-aadhar |title=Make biometric proof must for SIM card: Delhi Police commissioner Neeraj Kumar|work=The Economic Times |date=21 June 2013 |accessdate=11 January 2014}}</ref><ref>{{cite web|author=Rumu Banerjee |agency=TNN |url=http://articles.timesofindia.indiatimes.com/2012-06-06/delhi/32078084_1_licences-smart-cards-transport-department |title=Switch to smart card driving licences by July |work=The Times of India |accessdate=11 January 2014}}</ref><ref name="ref-650034820">{{cite web|url=http://www.karunadu.gov.in/karigr/actsrules/documentreg/6documentsforregistration.htm|title=Inspector Genaral of Stamps and Registration|publisher=karunadu.gov.in}}</ref>

Government also knows the movements of people thru the traffic cameras on roads, vehicle Number plate, face recognition etc. Use of electronic devices such as mobile phones, emails, internet, TV, bank cards provide no privacy. At any moment the Govt. knows of geographical location of people, what talk is going on phone with whom, what one is reading, writing or watching on internet, and what TV channel one watches when and for how long (it is the source of TRP data) thru the service provider. All it is done thru device identifiers like IMEI, IP address, GPS under electronic surveillance.

Police and other government departments conduct surveillance and crack crimes thru mobile phones of individuals. Location of mobile phone holder is known and call detail records (CDR) is available to government. Therefore, perhaps mobile phone is the largest violator of privacy. However, the privacy champions do not abandon the use of mobile phones and internet despite this knowledge.<ref>{{cite web|url=http://www.thesundayindian.com/en/story/when-mobiles-crack-crime/7/47303/ |title=When Mobiles Crack crime – Parimal Peeyush and K.S Narayanan |publisher=The Sunday Indian }}</ref><ref>{{cite web|url=http://www.wrdw.com/news/crimeteam12/headlines/Cell-phone-tracking-used-to-catch-Boston-bomber-local-criminals-204180651.html |title=Cellphone tracking used to catch Boston bomber, local criminals |publisher=Wrdw.com |date=22 April 2013}}</ref><ref>{{cite web |url=http://io9.com/how-police-caught-two-bank-robbers-using-verizon-cell-p-1232742089 |title=How police caught two bank robbers using Verizon cell phone data |publisher=Io9.com |date=25 November 2009}}</ref><ref>{{cite web|url=https://www.facebook.com/pages/Police-access-your-emails-websites-mobile-phone-data-to-catch-criminals/428292433868087 |title=Police access your emails websites & mobile phone data to catch criminals |publisher=Facebook }}</ref><ref>{{cite web|url=http://www.digitaltrends.com/social-media/the-new-inside-source-for-police-forces-social-networks/#!Awz43 |title=How police use social networks for investigations |publisher=Digital Trends |date=13 July 2013}}</ref><ref>http://www.usatoday.com/story/news/nation/2013/12/08/cellphone-data-spying-nsa-police/3902809/</ref>

==Budget, cost and benefits==
About Rs. 35&nbsp;billion (Rs. 3500&nbsp;crore) has been spent totally on Aadhaar program from inception (January 2009) till September 2013 with enrollment of 500&nbsp;million (50&nbsp;crore) persons.

The projected cost and benefit analysis report by National Institute of Public Finance and Policy shows that Aadhaar-enabled public welfare programs will be able to save Rs. 1.1&nbsp;trillion (Rs. 110,000&nbsp;crore) by the year 2020.<ref name="planningcommission" /><ref>{{cite web |url=http://www.nipfp.org.in/report/1204/ |title=web page |publisher=NIPFP |accessdate=31 October 2013}}</ref>

Tangible benefits become visible from 2014. A report of UBS Securities published in Jan 2014 shows that Aadhaar-DBT can save up to 1.2% of GDP. GDP of India is $1,800&nbsp;billion, thus the saving is $22&nbsp;billion (Rs. 1.32&nbsp;trillion), which ultimately translates to 33% savings on overall social security spending.<ref name="indiatimes5"/>

== Technology ==
Aadhaar Number (AN) is 12-digit in the format of 1234-5678-9012 where the 11-digits are used as a sequence and the rightmost 1-digit as an error detection ]. Verhoeff algorithm is used for check-sum; it only detects data-entry error and it does not correct the error for security reasons. It is supposed to be assigned to current population of 1.25&nbsp;billion and future growth for centuries. Since Aadhaar uses 11-digit for sequence, therefore it has an ] of 10<sup>11</sup> (100&nbsp;billion). So AN can be assigned to 100&nbsp;billion residents, and is designed not to get used up in the next 500&nbsp;years.<ref>Hemant Kanakia, Srikanth Nadhamuni, Sanjay Sarma (May 2010).

=== Requirement ===
All online data communication is encrypted and secure. System is scalable to handle the registration and authentication of identities in the largest biometric database of the world. It is English and Indian multilingual (Hindi, Punjabi, Kannada etc.).

Enrollment volume is 1&nbsp;million person per day, over 200&nbsp;trillion matches per day, 5MB per resident goes to database size of 15&nbsp;Peta Byte @ 2Kbit encryption, 30 TB of input-output per day, over 5TB of incremental data everyday. Lifecycle updates and new enrolments will continue forever.<ref name="slideshare.net" />

Authentication volume is 4KB packet of each authentications request of 100&nbsp;million requests per day, should handle high variance on peak-time and average, instant validation (under 10&nbsp;second), guaranteed audits. All changes needs to be propagated from enrolment office to all authentication systems. 1&nbsp;billion audit records in 10&nbsp;days (30+ billion a year), 4 TB encrypted audit logs in 10&nbsp;days, audit write must be guaranteed.<ref name="slideshare.net"/>

=== Design and tools ===
It is scalable system architecture based on distributed computing. Various tools and systems have been used like J2EE, MySql, Hadoop, HBase, MongoDB, Solr, Mule, Rabbit etc. All system communications are only thru ]. When everything fails i.e. hardware, software, network, storage then the System must recover, retry transactions and do self-heal.

High degree of security, privacy and scalability is built-in from start. It is open-source, multi-product, multi-vendor system with linear growth.

=== Testing ===
Aadhaar System development and testing has been done at the UIDAI Technology Centre at Bangalore. Pilot field testing have been done in Jharkhand state for authentication and payment of wages and social security benefits thru Aadhaar-enabled Bank Account (AeBA).<ref>{{cite web|url=http://priboghani.wordpress.com/2012/08/02/aadhaar-indias-answer-to-most-problems/ |title=Aadhaar: India’s answer to most problems? &#124; Glass Ceilings |publisher=Priboghani.wordpress.com |date=2 August 2012 |accessdate=11 January 2014}}</ref><ref>{{cite web|url=http://businesstoday.intoday.in/story/uid-project-nandan-nilekani-future-unique-identification/1/22288.html |title=Aadhaar: How the UID project can transform India |work=India Today |date=4 March 2012 |accessdate=11 January 2014}}</ref><ref>{{cite web|author=Sudhir Kumar Mishra |url=http://www.telegraphindia.com/1130812/jsp/jharkhand/story_17221827.jsp#.UoknIcRmiSo |title=Hemant meet on Aadhaar |work=The Telegraph|location=Kolkota |date=12 August 2013 |accessdate=11 January 2014}}</ref>

==Problem areas==
Although enrolling 1.25&nbsp;billion people with biometrics is the largest ever ID project in the world with lot of challenges, yet some reported problems have been compiled.

===Acceptance===
E-KYC is not being used for DBT of LPG at dealer's office. Beneficiaries have been asked to submit paper-based photocopy of Aadhaar letter, bank account and linking-form in old-style. Linking thru online self-service to bank account is not available.<ref>{{cite web|url=http://petroleum.nic.in/dbtl/lpgad.pdf |title=Form-2 (LPG Linking Form) |publisher=Petroleum.nic.in |accessdate=6 November 2013}}</ref><ref>{{cite web|url=http://petroleum.nic.in/dbtl/linkstatus.html |title=Aadhaar Linking Status |publisher=] |accessdate=4 November 2013}}</ref>

Bank Staff ask for original Aadhaar letter to be produced for verification when presented with printout of e-Aadhaar letter. They are not aware that Aadhaar is just a Number, not a Card which needs online verification with Aadhaar-database-server.<ref name=ahluwalia>{{cite web|url=http://www.ndtv.com/article/india/aadhaar-is-a-number-not-an-id-card-montek-singh-ahluwalia-325741 |title='Aadhaar' is a number, not an ID card: Montek Singh Ahluwalia |publisher=NDTV.com |date=2 February 2013 |accessdate=31 October 2013}}</ref>

Staff of some departments are not yet aware that Aadhaar can be accepted as a minimum KYC.<ref name="indiatimes4"/> Presently RTO accepts Aadhaar letter only as additional ID, not sole ID till the Motor Vehicle Act is amended.<ref name="indiatimes4"/>

Some politicians and middlemen have been vehemently opposing adoption of Aadhaar for the PDS Ration, therefore, corruption in PDS continues in those states.<ref name=tipping/>

===Enrolment===
People of some states, such as Uttar Pradesh, Bihar, Tamil Nadu and West Bengal are not aware that NPR (under the Ministry of Home Affairs) is responsible for Aadhaar enrolment in those areas.<ref>{{cite news|url=http://economictimes.indiatimes.com/slideshows/economy/all-you-want-to-know-about-uid-npr/states-aadhaar/slideshow/18832328.cms |title=States & Aadhaar – All you want to know about UID & NPR |work=The Economic Times |date=13 August 2012 |accessdate=4 November 2013}}</ref><ref>{{cite web|url=http://ditnpr.nic.in/NPR_Activities.aspx |title=NPR Activities |publisher=National Population Register |accessdate=5 November 2013}}</ref>

===Aadhaar letter delivery problems===
The public is generally not aware of E-Aadhaar download (self-service to download pdf copy).<ref name="indiatimes3"/><ref name="uidai2">{{cite web|url=https://eaadhaar.uidai.gov.in/ |title=e-Aadhaar by Unique Identification Authority of India |publisher=Eaadhaar.uidai.gov.in |date=10 October 2013 |accessdate=4 November 2013}}</ref> Aadhaar letter is not delivered by India Post after 3&nbsp;months, it takes 6 to 9&nbsp;months after enrolment.
