UIDAI launches Updated QR code for offline Aadhaar verification
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.
QR code (Quick Response code) is two-dimensional (matrix) machine-readable bar code made up of black and white square. This code can be read by the camera of a smartphone. It is used for storing URLs or other information that link directly to text, emails websites phone numbers. It is capable of 360 degrees (omni-directional), high speed reading.
QR Code can store up to 7089 digits as compared to conventional bar codes which can store max 20 digits. It encodes same amount of data in one-tenth the space of a traditional bar code. It carries information both horizontally and vertically. It has error correction capability and data stored in it can be restored even if it is partially damaged or dirty.
