FinAuth is an identity verification SDK that delivers production-grade KYC and biometric authentication through a single REST API or a fully offline, hardware-bound SDK. It combines NIST FRVT #1-ranked face matching, iBeta Level 2 anti-spoofing liveness detection, document OCR supporting 200+ ID types, and AML watchlist screening. The platform offers both a hosted cloud API for instant deployment and an offline SDK for air-gapped, GDPR-sovereign environments.
