Acceptance of Aadhaar based authentication. The new role it plays!

Aadhaar, meaning ‘dependence’ in Hindi is introduced for all our futuristic justifications. Our signature, photocopy or citation are clueless to find their uniqueness in this new era. To mark an end to old school debris we have been bringing in, our government conceptualised a new identification for all its citizens. A step more towards a clean, safe and generalised new India. Versatility which once never found it’s existence outside dictionary, now sounds it’s exact meaning in different languages of India through people.

What makes Aadhaar so unique?

We guess, the question should have been “Why other identities are almost baseless?”. Surviving in this technology dominated world without having experience of digitisation is no less than a struggle for a fast-developing country like India. Having a bit less population than China and bit more area than Argentina, India is the fastest developing density borne country with a GDP similar to Australia. Reliability over identity needs lot more authentication than just few paperwork.

How other paperwork define our identity? Name, Parents’ name, Gender, DOB, Address and at most, occupation. Are they full proof for future? Can’t anyone generate a duplicate of such IDs? Pretty obvious QnAs, Right? India until recently, had no option to uniquely recognise a citizen through advanced technology. Aadhaar is the answer it gave to all those queries simultaneously. Every individual needs to share his/her biometrics data like fingerprint, iris and digital credentials like his/her personal mobile number and email id. Facial recognition algorithm through pre-existing photographs is another sweet cream. All these make this e-document a full-fledged future proof identifier of a citizen.

How Aadhaar authorise your identity over the Internet?

Types of Aadhaar Authentication:


  1. Mobile SMS OTP based.
  2. E-mail OTP based.


  1. Fingerprint
  2. Iris
  3. Facial Recognition (coupled with fingerprint, iris or OTP)

This short process of authentication is ping based and takes few seconds to complete if everything works fine. You need to provide your 12-digit Aadhaar number and authenticate it through OTP sent by SMS or through biometrics. In situation where task isn’t very sensitive, OTP is more than sufficient. (E.g. mobile number link) Biometrics are required in heavy applications wherein physical presence of applicant is compulsory. Recently, virtual wallets had to have full KYC for general usage which required an Aadhaar OTP based authentication.

UIDAI considers fingerprint and iris authentication to be most reliable because of their precision in uniqueness. Transactions through iris scan is always given clearance as that’s practically the safest in India. Iris scanners are present in limited numbers and scamming through the system is equally tough. However, for the sake of versatility people prefer fingerprints everywhere. Biometrically, most of the time they are easy to scan, fast and responsive.

We always recommend you to check the supervisor’s or merchant’s computer/mobile screen to know the actual use of your fingerprint verification during an Aadhaar session. Always make sure that the task is relevant to you or to your needs. Defend or cancel any transaction you find against your will or fraud. Visit Authentication History to keep track of all your past verifications. Report anything suspicious to UIDAI directly through the portal and request to withdraw any unknown service(s) enabled.

Never share your actual Aadhaar number to stranger under any circumstances. Only when deemed necessary, present the document or the number to reliable official. UIDAI has announced to bring in a whole new system of 16-digit temporary dynamic number to proxy your Aadhaar, making it safe for short term use.

Bank transactions through Aadhaar:

AEPS (Aadhaar Enabled Payment System) is a new simplified way to transfer or withdraw money from bank account. It uses the same network and your bank needs to have link to your Aadhaar to avail this free service. In case of multiple accounts, the user has the option to manually select or the lastest bank linked gets selected by default. UIDAI has sustained some limitations in daily ping, as a result, excessive use and load over servers are reduced.

However, there are some constraints which AEPS may cancel out at later stages. For example, you can’t use this system to withdraw cash from ATM due to lower confidence of maintenance in case of implementation. Additionally, biometrics enabled ATMs are pretty costly to manufacture and require better layers of software security enhancements. NPCI is busy planning all these, delighting our hope for a free true cardless society. Till then “No card, no worry!” remains to be a dream among youths.
