The Unique Identification Authority of India (UIDAI) has introduced updated ‘QR code’ for offline Aadhaar verification to strengthen its privacy measures during usage. The updated ‘QR code’ is aimed at adding an extra layer of privacy to Aadhaar after UIDAI introduced the concept of virtual identification.
The updated ‘QR code’ will only reveal non-sensitive details such as name, address, photo, and date of birth. It can be used for offline user verification without disclosing 12-digit aadhar identification number. The new QR code comes with photo and can be used in offline mode to safeguard against any tampering of documents.
aadhaar card holders can download and print their biometric ID with QR code from UIDAI website or its mobile app. Users also can manually blacken aadhaar number and use printout with new QR code for establishing their identity, offline too. The printed QR code when scanned will only read non-sensitive information without revealing 12-digit aadhar identification number.
