The Unique Identification Authority of India (UIDAI) has launched a new service called “Aadhaar”. Aadhaar is a 12 digit individual identification number issued by the UIDAI on behalf of the Government of India. It captures all your demographic and biometric information which can be used to identify you anywhere, anytime in an easy and convenient way. This number will serve as proof of identity and address anywhere in India. Aadhaar is not just another ID but it’s unique because it’s linked with many other services like bank accounts, mobile phone connections etc., so that you don’t have to carry multiple IDs everywhere you go. You can use this single document for everything from opening a bank account or getting a passport to filing income tax returns or booking railway tickets online!
