Biometric Verification with Goverlink™ in Brazil
Bynn always performs biometric verification for every Goverlink™ identity check in Brazil when possible. We compare facial biometrics from the government ID, a live selfie (liveness check), and official government databases 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.
