From October 8, 2025, millions of Indian UPI users can validate payments using fingerprint or face recognition as an alternative to the conventional numeric PIN. The feature, called on-device biometric authentication, leverages smartphones' built-in security features linked with the Aadhaar system.

Initially, biometric transactions are capped at ₹5,000. Biometric data is processed on the user's device and not shared with NPCI or banks, ensuring privacy. The Department of Financial Services Secretary M. Nagaraju unveiled the feature at the Global Fintech Festival 2025 in Mumbai. NPCI clarified the feature is optional, enhancing customer experience without replacing PIN-based authentication.
