All about UIDAI and Aadhaar

Read on to know all about the Aadhar card and the ways in which its use in real estate transactions can actually be a good thing

Unique Identification Authority of India (UIDAI) formed in 2009 by the Planning Commission, is a government body which gained statutory legalisation under the provisions of the Aadhaar Act of 2016 by the Government of India. The government, in a bid to deal with the menace of corruption and black money, has hinted that it may consider linking immovable properties with Aadhaar numbers. If such a move is implemented, it will have widespread ramifications and make the implementation of the benami transactions law easier.

UIDAI is the body which authorises Aadhar card to the citizens of India. The main motive of this enactment was to provide Unique Identification Numbers to every resident of India which would be named as Aadhar card, in which the card was to be robust enough to flush out duplicate entries into the databases of UIDAI and give the cardholders assurances about their ID’s validity and authenticity that too without paying much in fees to them. Currently, the number of Aadhaar cards to have been issued is more than 120 crores.

The Aadhaar Act 2016 gives power and responsibility of enrolling new applicants and other important operations about the Aadhar card, including the security of the database and creation of a robust management system to the UIDAI.

What is Aadhar and how it was created?

Aadhar is the world’s largest Identification system which uses biometrics for validation. Every Aadhar card has a unique 12-digit random number which is generated by UIDAI after careful validation of the details enrolled by the applicant. Aadhar is termed as a resident proof instead of a citizenship proof, as it doesn’t provide any domicile rights to anyone. The Home Ministry has also clarified that places like Nepal and Bhutan don’t recognise Aadhar as a valid proof of ID for Indians.

Formed in 2009 by then the Planning Commission of India, it got legislative validity in 2016 after a bill was passed in the Parliament. In 2012, UIDAI launched online verification of Aadhar numbers which could be used by telecom companies to verify a person’s ID instantly. In the same year, then PM Manmohan Singh initiated direct benefit transfer scheme which would target the leakages in the transferring of wealth directly onto the pockets of the poor in various national welfare schemes by linking Aadhar cards to the bank accounts of the recipients.

Is Aadhaar mandatory for all Indian citizens?

According to the Supreme Court’s ruling in 2013, Aadhar card is voluntary and not mandatory. No citizen of India should be disallowed welfare from the government based on his/her Aadhar number’s availability, as it only distinguishes the Identity of a resident and doesn’t validate anyone’s citizenship. The DBT scheme which was to be established using Aadhar linkage got a slowdown due to this decision, but the positive side of this is that more and more people are voluntarily enrolling themselves in the Aadhar Database due to this service being provided to them free of cost.

Since the government is planning to link all immovable properties to Aadhaar numbers, in case more than one property is purchased by a person, it will also be detected and make the task of the I-T Department easy, in detecting tax evasion through benami transactions in real estate. The use of black money may reduce due to this requirement, as only the person who has the funds will be able to buy the property. Hence, real estate prices will become stable and the abnormal volatility/speculation in prices, will reduce.


Is Aadhar globally recognised?

World Bank’s chief economist described Aadhar as the most sophisticated ID system of the world as it stores the information of the applicant in a secured database and retrieves that data efficiently by using the biometrics of an individual.

Aadhaar versus Passport

As of now, the Aadhar card given by the UIDAI is only used as a biometric-based Identification apparatus for every Indian resident by the Indian Govt. It is not a substitute or a kind of supplement to the Indian passport, which is primarily used as a valid ID in the global scene. However, Indian passports are issued by the government much faster if you can provide Aadhar number to the issuing agency which enables them to dole out your passport very quickly, as it becomes quite easy to verify the credentials of the passport applicant.

Can you hide your Aadhar from banks and other NBFCs?

In 2018, SC reversed the verdict of its earlier hearing in which they made it mandatory for someone wishing to open a bank account must produce Aadhar number before the bank. As of now, along with getting a new sim card or an admission into a school, bank cannot force the applicant to submit his/her Aadhar number. It is mandatory to link your Aadhar card to your PAN card which is generally demanded by a bank to validate your credentials.

Even though SC has made Aadhar number non-mandatory to be acquired from the applicant by those various agencies, government of India has time and time again persistently pushed the initiative of linking your Aadhar cards with portals like banks, mobile phones and other various welfare schemes as it helps them to flush out duplicates and transfer the benefits directly into the bank accounts of the intended people eliminating leakages of funds.

What if you don’t have an Aadhaar number – here’s how you can get one.

As benefits aligned with Aadhar card are established, now the question arises of how one can get this card and where must they apply for to receive this free of cost Aadhar. There are various steps one must follow which are easily doable if you have diligently prepared what’s necessary for those steps.

The first thing an applicant must do is to gather all the necessary documents required/listed by the UIDAI, as this ensures the process of enrolment of the application for a new Aadhar to commence without any further delay. They require and ask every applicant to submit his/her address proof & identity proof; therefore, you must carefully arrange copies of documents about these parameters.

Following this, one can now move onto the steps which lead one to apply for the enrolment in Aadhar database.

Biometric data collection

All the applicants are required to give their biometric inputs to the authorities as these are the fundamental aspects of Aadhar.

  • Iris scan
  • Fingerprint scan

Additionally, they will also take a snapshot of your face; this photo will be used on the actual card to be printed.

 Where can Aadhar be used?

It is important to remember that unlike other government agencies, for example, Voter Id card issued by ECI, Aadhar doesn’t serve a primary purpose of validating a person’s credentials for a particular entity but only holds a position of giving identification proof for every Indian resident.


  1. Direct benefit transfer –

Can the Aadhaar be misused?

As everyone is encouraged to get enrolled under UIDAI for Aadhar number, there is a looming danger over the heads of UIDAI database management system to provide a kind of security which ensures every Aadhar cardholder of its confidentiality as there are more than 120 crore Aadhar cards issued. Linked with so many other agencies and instruments of authority, it becomes a target for the hackers and other infiltrators. So, handling such a huge amount of data with the utmost care, diligence and security is one of the topmost priorities for the UIDAI.

There were numerous rumours regarding the security aspect of Aadhar in the mainstream media, as speculations surfaced over the web about Aadhar’s data being easily available for mere Rs. 500 for any individual. The media speculated further on this that over a billion Aadhar card’s details were up for grab for just Rs. 500.

As this gained momentum, the UIDAI was quick to dispel these rumours as fake news. They quickly assured the people of India that their details were secured and safe, as no successful breach was made to infiltrate UIDAI’s database. Aadhar, according to UIDAI authorities, is one of the most secured biometric systems that its holders can be assured that their data will never be leaked to other people who have no authority over those details.

As of now, there is no concrete evidence about Aadhar details being leaked onto the public domain from any source whatsoever. Even then, people must not overlook the possibilities of their data getting leaked by other means than digital medium. Physically the card could be misused by people with vile intentions.


Precautions to take to avoid Aadhar misuse

The Aadhar initiative over the years have covered almost 95% of the populace of India, for this, the UIDAI under direct orders from the union government has provided a sophisticated security system which works in encrypted layers determining the identification and credentials of every unique ID in their database. Even after such means of security for the confidential information, every cardholder must ensure that their details are not leaked from their side by taking some important measures which would curtail every possible hole of breach available for misuse of Aadhar by hackers or other unauthorised personnel.

These are the steps one must do to ensure that their information regarding Aadhar is never misused by anyone else.

Is Aadhar required in real estate transactions?

The basic aim of the government is to curb the massive influx of black money in the real estate market, therefore, implementation of Aadhar based transactions for this market is a bold move by the government as it allows them to monitor all the transactions and find the illicit dealings which include black money and other forms of corrupt practices.

Can Aadhar help avoid fraud in real estate transactions?

The government of India has made Aadhar-enabled authentication mandatory for property registration in India after amending the Registration Act. The prime motive behind this move was to provide the real estate market with a mean to curb black money and impose a penalty to individuals investing their black money into this market.

After the enactment of Benami Act, the government will be able to identify individuals who have brought a property by using black money as the registration of that new property will require submitting their PAN card and ITR file will provide details about the individual’s income and fund information. Supplementing this, the Aadhar card will give the Identification of the buyer to the government. Therefore, under the double supervision of Aadhar and the Benami act, frauds of buying a property under the false ID will be reduced and help curb corruption on a mass scale.
