Role of Biometric Devices in AEPS

Biometric devices play an important role in AEPS (Aadhaar Enabled Payment System) by allowing customers to verify their identity through biometric authentication, mainly using fingerprints or iris scans. AEPS enables Aadhaar-linked bank account holders to access services such as cash withdrawal, balance enquiry, cash deposit and mini statement through authorised banking agents and micro-ATM touchpoints. 

For customers, an AEPS biometric device makes banking simple and convenient because authentication can be completed without relying on a physical debit card. For retailers, CSPs and Business Correspondents, the device is an essential part of providing assisted banking services at the last mile. 

Biometric devices use unique physical or behavioral traits to verify identity and secure physical or digital spaces.

At AEPS India, understanding the role of biometric devices is important for choosing a reliable and compliant solution. UIDAI states that only Registered Devices are permitted in the Aadhaar authentication ecosystem, with registered devices designed to help protect biometric data integrity and prevent replay or tampering. 

This guide explains what an AEPS biometric device is, how biometric authentication works in AEPS, its role in transaction security, benefits for retailers and customers, and what to consider when choosing an AEPS biometric device in India. 

What Is a Biometric Device in AEPS?

A biometric device in the Aadhaar Enabled Payment System (AePS) is a hardware tool that captures unique physical traits like a fingerprint or iris scan to verify a customer’s identity for cardless and PIN-less banking transactions.

How Do Biometric Devices Work in AEPS?

Biometric devices in the Aadhaar Enabled Payment System (AePS) capture and encrypt unique physical traits like fingerprints or iris patterns to securely verify a user’s identity with the government database in real-time.

How the Process Works

• Data Input: The customer provides their 12-digit Aadhaar number and selects their bank name on a point-of-sale (PoS) or micro-ATM terminal operated by a banking correspondent.
