Aadhaar card biometrics lock and unlock on www.uidai.gov.in: Step-by-step guide

Aadhaar cards these days have become a necessity. From buying cars to houses or investing money, Aadhaar cards are mandatory. These cards also contain a lot of confidential information like name, address, date of birth, and biometric scans. To maintain confidentiality, Aadhaar authorities give people a great option -- locking and unlocking their Aadhaar details. 

It is very important to lock your Aadhaar card details if you don't want them misused. The unique Identification Authority of India gives people two options.
