In a move that promises to enhance security and convenience, the National Payments Corporation of India (NPCI) is reportedly exploring the possibility of replacing traditional OTPs and PINs with biometric authentication for UPI transactions. This development comes on the heels of the Reserve Bank of India's push for alternative authentication methods.   

The proposed system is expected to allow users to verify payments using fingerprints on Android devices and facial recognition on iPhones. This would streamline the payment process while significantly bolstering security against fraud. 

While the exact timeline for implementation remains unclear, the potential shift towards biometric authentication marks a significant step forward in India's digital payments landscape.
