Aadhaar is a widely used identity for verification in India. Whether it’s a fintech company, a bank, a recruitment firm, or any other organization, it relies on Aadhaar to verify individual legitimacy. Organizations that wish to conduct verification must access the UIDAI records for accurate verification. However, without proper authorization from UIDAI, no one can access the sensitive Aadhaar data of an Individual. As millions of verifications need to occur daily.
