UIDAI – Overview

The government of India has made strides towards safeguarding the citizen’s financial and personal details over the years. This has helped reduce the frequency of incidences like money laundering, corruption, and identity theft. Although the rise in technology has made ordinary lives easier and more comfortable, it has also made people more vulnerable to fraudulent practices. The rate of cyber theft has been at an all-time high currently. In a move to combat the increasing rate of financial malpractices, the Government of India launched the UIDAI.

What is the UIDAI?

The Unique Identification Authority of India or UIDAI is a central government authority that functions to accumulate the country’s citizen’s personalized data such as fingerprints, photographs, and eye scans in the form of biometric collection under the different demographic divisions of the country and store them for information tracking. For record-keeping, the UIDAI issues Aadhaar card which contains a 12-digit unique code for each individual.

This Aadhaar card is now being used as a nationwide identification document and has become an essential document for every Indian citizen to have.

History of the UIDAI

The Unique Identification Authority of India was founded in January of 2009 with Nandan Nilekani as the appointed chairman. The UIDAI logo and the name ‘Aadhaar’ were also designed by Nilekani which was released in April 2010.

The authority undertook the service of enrollment by listing about 220 qualified agencies that were to participate in the enrollment process. A total of 15 agencies were also listed to train the personnel about the enrollment process.

The UIDAI launched an online platform for the verification of Aadhaar on February 7th, 2012 through which a citizen can verify citizenship using his/her respective Aadhaar number.

It was only in November of 2012 that the Aadhaar gained popularity and it was due to the then Prime Minister, Dr. Manmohan Singh’s call of a benefit transfer scheme which was Aadhaar-linked. This scheme was launched to track money transactions and prevent any leakage in the system with a direct transfer of money to the recipient’s bank account. What started as a scheme for 20 states went on to have a nationwide spread.

The characteristics of Aadhaar were laid out by the Supreme Court on August 11th,2015 where it was mandated that UIDAI or Aadhaar card is to be used for purposes such as Kerosene, PDS, and LPG distribution.

The year 2016 was monumental in the UIDAI history because on March 11th of this year, the Lok Sabha passed the Aadhaar act. This came into effect after the money bill which was introduced in the parliament during March 2016. Later, on March 26th, 2016 this Aadhaar act became a part of the Gazette of India. As per the recent records from the UIDAI, a total of 40,810,314,699 authentications have been done by the authority and about 1,257,514,195 people have generated Aadhaar card. This data alone can justify the immense growth of the UIDAI throughout the years where almost every government/non-government procedure incorporates Aadhaar as a means of identification.
