The Unique Identification Authority of India- UIDAI is a legal authority established under the requirements of the Aadhaar Act, 2016 – an act formed for targeting the delivery of financial and other subsidies, benefits as well as services, by the Government of India, under the Ministry of Electronics and Information Technology. Aadhaar number is free of any intellect and does not profile people based on class, religion, salary, health and topography.

The Aadhaar scheme has already accomplished many landmarks and is by far the biggest biometrics-based proof of identity system in the whole world.
