India

India is one of the most advanced countries for government verification through Bynn's Goverlink™ technology. With direct integration to the Unique Identification Authority of India (UIDAI), Bynn can verify identities against the Aadhaar database - the world's largest biometric identity system.

As of 2025, more than 1.35 billion people in India have enrolled in Aadhaar, making it the most comprehensive identity verification system globally available through Bynn's platform.

Biometric Verification with Goverlink™ in India

Bynn always performs biometric verification for every Goverlink™ identity check in India. We compare facial biometrics from the government ID, a live selfie (liveness check), and official government databases like Aadhaar when available. This ensures the person is real, present, and matches a verified identity. The liveness detection prevents spoofing with photos or AI-generated images. With this multi-source biometric match, Bynn delivers secure, fraud-resistant verification trusted across regulated industries.

Verification Overview

India verification through Goverlink™ provides real-time authentication against official government databases maintained by UIDAI. This system offers multiple verification methods to accommodate different business requirements and user scenarios.

Supported Verification Types:

Verification TypeData VerifiedBiometricReal-time
Demographic
Biometric
eKYC
Offline XML
QR Code

Processing Time: Typically 1-10 seconds for all verification types

Aadhaar System

Aadhaar is India's foundational identity document, providing a unique 12-digit identification number to residents. The system is managed by UIDAI and serves as the primary identity verification method for government services, banking, and digital transactions.

Key Components:

  • 12-digit unique Aadhaar number
  • Demographic information (name, date of birth, gender, address)
  • Biometric data (fingerprints, iris scans, facial photograph)
  • Mobile number linkage for OTP services

Coverage: Available to all Indian residents regardless of citizenship status

Verification Methods

Demographic Verification

Validates the existence of an Aadhaar number and cross-references basic demographic information against UIDAI records. This method provides fast verification of identity data without requiring biometric authentication.

Verified Data Points:

  • Aadhaar number validity
  • Full name matching
  • Date of birth verification
  • Gender confirmation
  • PIN code validation

Requirements: Valid 12-digit Aadhaar number and corresponding demographic information

Biometric Authentication

Authenticates users through fingerprint or iris biometric matching against UIDAI's centralized biometric database. This method provides the highest level of identity assurance by confirming physical presence.

Supported Biometric Types:

  • All 10 fingerprints
  • Both iris scans
  • Facial recognition (where available)

Requirements:

  • Certified biometric capture device
  • High-quality biometric templates in ISO format
  • Valid Aadhaar number

Device Compatibility: Supports UIDAI-certified biometric devices for fingerprint and iris capture

eKYC (Electronic Know Your Customer)

Performs comprehensive identity verification using OTP sent to the Aadhaar-linked mobile number. Returns complete demographic and address information along with official photograph.

Verification Process:

  1. OTP request to registered mobile number
  2. OTP validation and consent confirmation
  3. Complete eKYC data retrieval from UIDAI

Returned Information:

  • Full demographic details
  • Complete address information
  • Official Aadhaar photograph
  • Contact information (email and mobile)

Requirements: Mobile number must be linked to Aadhaar account

Offline XML Verification

Verifies digitally signed XML files that users can download from the UIDAI resident portal. This method enables verification without requiring online connectivity to UIDAI systems.

Verification Capabilities:

  • Digital signature validation
  • Data extraction and verification
  • Photograph extraction
  • Timestamp verification

Requirements:

  • Offline XML file from UIDAI portal
  • 4-digit share code provided by user
  • Valid digital signature

QR Code Verification

Validates QR codes found on physical Aadhaar cards and e-Aadhaar documents. Provides instant verification of printed or digital Aadhaar credentials.

Verification Features:

  • QR code signature validation
  • Demographic data extraction
  • Photograph hash verification
  • Issuer authentication

Supported Formats:

  • Physical Aadhaar card QR codes
  • e-Aadhaar document QR codes
  • mAadhaar app QR codes
