Aadhaar Biometric Authentication System Overview

Aadhaar authentication system comprehensive identity verification infrastructure India.

System Definition:

Aadhaar biometric authentication = Government-backed identity verification using fingerprints, iris scan, facial recognition. Purpose: Enable cashless banking, government benefits access, digital services authentication. Coverage: ₹1.3 Cr registered Aadhaar population India. Managed: UIDAI (Unique Identification Authority India) under Ministry of Electronics Information Technology. Technology: 10-fingerprint scan, iris biometric, facial recognition, demographic data.

Authentication Methods Available:

Method 1: Fingerprint authentication (primary)

Method 2: Iris scan authentication (secondary)

Method 3: Facial recognition (emerging)

Method 4: OTP authentication (tertiary alternative)

Method 5: E-Aadhaar virtual ID presentation

Method 6: Demographic authentication (name-DOB-address)

Method 7: Physical Aadhaar card presentation

Authentication Failure Consequence:

Banking transactions blocked AEPS terminal rejection
