Aadhaar authentication provides several ways in which a resident can authenticate themselves using the system. At a high level, authentication can be ‘Demographic Authentication’ and/or ‘Biometric Authentication’.

During the authentication transaction, the resident’s record is first selected using the Aadhaar Number and then the demographic/biometric inputs are matched against the stored data which was provided by the resident during enrolment/update process.

Fingerprints in the input are matched against all stored 10 fingerprints.
