Aadhaar verification now possible offline, without disclosing 12-digit ID number
Aadhaar cards will now have an updated QR code, making user verification possible even offline, without the 12-digit ID number. The digitally-signed QR code on e-Aadhaar will have user's photograph along with other non-sensitive demographic details such as name, address and date of birth. With Aadhaar increasingly being used to avail all kinds of services, the new QR code will ensure quicker, safer verification.
The updated QR code enables offline use of Aadhaar, thus protecting your sensitive details against any probable tampering. Moreover, offline verification doesn't require Aadhaar number or biometrics, ensuring complete privacy. It would be especially useful for proving identity with non-statutory entities like online shopping portals. Lastly, it would ensure no Indian is ever denied an Aadhaar-based service because of verification hurdles.
A type of barcode label containing machine-readable information, the updated QR code will have a UIDAI digital signature, making the details more secure and tamper-proof. You can download, print your biometric ID and QR code from the UIDAI's website or mobile app. For offline identity verification, you can manually blacken your Aadhaar number, get its printout with the updated QR code and use it.
However, to verify the user's identity, the photo on Aadhaar will be checked with the person's face or through an agency specific authentication scheme. Meanwhile, the UIDAI has made the e-Aadhaar QR code reader software available on its website from March 27, 2018.
