As of my last knowledge update in January 2022, AEPS (Aadhaar Enabled Payment System) and Aadhaar Pay are government-initiated systems in India aimed at facilitating digital financial transactions, particularly for individuals who may not have access to traditional banking services. These systems utilize Aadhaar, India's biometric identification system, to enable secure and convenient payments.
AEPS allows Aadhaar-linked bank account holders to carry out financial transactions using their Aadhaar authentication. It enables services like cash withdrawal, cash deposit, fund transfers, balance inquiry, and other banking activities through Micro-ATMs or banking correspondents using fingerprint or iris authentication.
Aadhaar Pay, on the other hand, is specifically designed for merchants and retailers to accept payments from customers using their Aadhaar-linked bank accounts without the need for cards, PINs, or smartphones. Customers can make payments by authenticating their identity through biometric details linked to their Aadhaar.
