QR Code Reader
Introduction
QR Code earlier present on Aadhaar print-letter and e-Aadhaar contained only the demographic information of the Aadhaar number holder. UIDAI has introduced new Secure QR Code which contains demographics as well as photograph of the Aadhaar number holder. Information in the QR Code is secure and tamper-proof as it is digitally signed by UIDAI.
The new digitally signed secure QR code can be read using UIDAI’s custom application and validate it against UIDAI digital signatures on real time. Therefore, any fraud attempted on Aadhaar can be easily detected by using QR Code scanner.
By scanning the Secure QR Code on the presented Aadhaar/ e-Aadhaar, the identity of the presenter can be verified.
