Answer: Himachal Pradesh
Notes: Himachal Pradesh became the first state in India to launch Aadhaar-based face authentication (FaceAuth) for ration distribution under the Public Distribution System (PDS). Earlier, authentication was done using One-Time Password (OTP) or biometric methods. These traditional methods faced problems like SMS failures and fingerprint mismatches at the Unique Identification Authority of India (UIDAI) end. The new FaceAuth uses a mobile camera through an app on the fair price shop (FPS) owner’s smartphone for facial verification. It was introduced by the Department of Digital Technologies and Governance (DDTG), Himachal Pradesh.
