Issues
A large number of people remain without identity documents - poor people especially. In order to include them, identity requirements for Aadhaar have been reduced, however biometric facilities have been provided to reduce or eliminated duplication, so while it may be possible to obtain the card under a false name, it is less likely to be able to obtain another Aadhaar card under a different (or real) name, though there have been cases where the biometrics has been circumvented.

There was a criticism that India has too many Identity systems, and they are not consistently accepted. As a solution, GOI introduced Aadhaar Cards in 2012, which is most widely accepted identification document in India and can be easily obtained by any person of any age group.
