During an authentication transaction, the resident's record is first selected using the Aadhaar number and then the demographic/biometric input is matched against the stored data that was provided by the resident during the enrollment/update process. The fingerprints in the input correspond against all stored 10 fingerprints.
When the Aadhaar (AADHAAR) number is activated, the website will confirm that your Aadhaar (AADHAAR) number is present. Other details will also be shown. For example, in which age group you live, in which state you live, what are the last three numbers of your mobile number, etc.
