As a Safe eTransactions Motivator, on implementation of this scheme will lead to a massive boost in eBanking transactions. Yes, we Indians are tech-savvy, and can adapt to new technologies very fast.

Mobile phones are important tool in the Aadhaar set-up too.

Let us wait and see what the future holds for Mobile Banking in India.

UIDAI clarifications: Cut away portion, eAadhaar valid proofs of identity, address

A majority of complaints regarding Aadhaar Cards is that many institutions / departments are refusing acceptance of cut away portion of Aadhaar letter as a valid document.

UIDAI has clarified that ‘The Information Technology Act, 2000’, provides for legal recognition of electronic records with digital signatures.

It may be noted that eAadhaar is digitally certified. Hence, e-Aadhaar or cut-away portion of Aadhaar letter can be considered a valid proof of identity and address.

The UIDAI which is implementing the Aadhaar project clarified in a statement that both — e-Aadhaar and cut-away portion of Aadhaar letter, is to be considered as a valid proof of identity and address.

According to the UIDAI, the e-Aadhaar document is digitally signed, using certificate issued by NIC as per the IT Act.

Further, all the data printed in eAadhaar is the same data as printed in Aadhaar letter, making it a valid and secured electronic document, which should be treated at par with a printed Aadhaar letter.

A “Resident Portal” had been launched to enable the residents download their e-Aadhaar, an electronically generated Aadhaar letter, from the website of UIDAI.

In addition, Common Service Centres, set up in States, are also catering to the needs of the residents with regards to download and printing of e-Aadhaar.

UIDAI said the cut away portion of Aadhaar letter is as an officially valid document as it contains all the details of Aadhaar letter such as name, address, Aadhaar number, photograph and logo of the Aadhaar Project.

The cut away portion of Aadhaar letter also carries a quick response (QR) code containing the demographic details of the resident.

However, it is yet to be seen as to how departments/organizations accepting Aadhaar Cards as Identity/Address Proof, treat eAadhaar letters.

The actual UIDAI-Aadhaar number is 11 digits long and not 12 digits!!!


The actual UIDAI-Aadhaar number is 11 digits and not 12 digits. Well, do not be surprised.

The first 11 digits of the 12 digit Aadhaar number displayed on your Aadhaar card is the actual UID Number and the 12th digit is the checksum associated with Verhoeff Algorithm scheme.

What is Checksum?

The checksum is the last digit in the number series of a number, through which data-entry errors can be eliminated to a large extent.

The purpose of check digits is simple. Any time identifiers (typically number +/- letters) are being manually entered via keyboard, there will be errors. Inadvertent keystrokes or fatigue can cause digits to be rearranged, dropped, or inserted. The most common example is of misdialing phone numbers.

Check digits help to reduce the likelihood of errors by introducing a final digit that is calculated from the prior digits. Using the proper algorithm, the final digit can always be calculated. Therefore, when a number is entered into the system (manually or otherwise), the computer can instantly verify that the final digit matches the digit predicted by the check digit algorithm. If the two do not match, the number is refused. The end result is fewer data entry errors.

In today’s world, two checksum algorithms are widely used. There are

01) Luhn algorithm.

02)                Verhoeff algorithm.

The Luhn Algorithm’s most common usage is in the generation of credit card numbers.

The Verhoeff algorithm’s most common usage is in the UIDAI-Aadhaar number generation program.

The Verhoeff algorithm is a complicated one, and cannot be calculated manually. This is suitable for computer-era.

The Verhoeff algorithm, a checksum formula for error detection first published in 1969, was developed by Dutch mathematician Jacobus Verhoeff (born 1927). Like the more widely known Luhn algorithm, it works with strings of decimal digits of any length. It detects all single-digit errors and all transposition errors involving two adjacent digits.

As 100 crores+ Aadhaar numbers will be generated, the Verhoeff Algorithm was the chosen one. And, it is not expected that any one will try to manually validate the Aadhaar number.

Aadhaar number is a random generated number, with no preset formula like the other Indian numbers, be it Pin code, IT PAN, Passport Number or Bank Account number.

Computerworld Honors 2013: Economic Development Winner – Aadhaar


UIDAI has one more feather in its cap. It is the winner of Computerworld Honors 2013 under Economic Development.

ComputerWorld describes Aadhaar as : : ID program empowers citizens in India

Government program, the 21st Century Achievement Award winner for economic development, uses biometrics to assign unique identity numbers, allowing residents of India to participate more fully in society.

The Computerworld Honors Program was established in 1998 with the aim to bring together the men, women, organizations and institutions around the world whose visionary applications of information technology promote positive social, economic and educational change.

The 2013 Awards are the 25th in the annual series.

The other finalists in the race were:

  1. Engro Milk Automation Network (EMAN),
  2. Solar Sister Program,
  3. African Cashew Initiative (ACi),
  4. Empowering Rural Women and Providing Sustainable Access to Market
