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.
