The Aadhaar Enabled Payment System (AEPS) depends heavily on biometric authentication to perform secure banking transactions.
Biometric devices—especially fingerprint scanners—are the core component that enables identity verification in AEPS.
Without biometric devices, AEPS simply cannot function.
What are Biometric Devices in AEPS?
Biometric devices are hardware tools used to capture a user’s:
- Fingerprint
- Iris (in some advanced systems)
These devices authenticate identity using Aadhaar data.
