UIDAI has replaced existing QR code, on e-Aadhaar, having Resident’s demographic details with a secured QR Code which contains demographics along with photograph of the Aadhaar holder. There will be two QR Codes – Small one on front side of cutaway portion with demographic data only; and a large one on top portion of front side and rear side of cutaway portion, with demographic data and photo. Further, to make this Information more secured and tamper-proof, it will be signed with UIDAI digital signature. This new digitally signed QR code can be read ONLY using UIDAI’s windows based Custom client for desktops/laptops and validate it against UIDAI digital signatures in real time. Therefore, any fraud attempted on e-Aadhaar can be easily detected by using QR Code scanner.
