Passport verification has evolved from manual document inspection to digital methods centered on chip-based NFC verification and cloud-based analysis. NFC reads ePassport chips to cryptographically validate stored biographical and biometric data against issuing-country certificates, providing strong protection against document tampering and supporting live facial matching for high-security settings such as border control. Cloud-based systems use OCR, databases, AI fraud detection, liveness checks, and watchlist screening to process identity information at scale and add broader risk intelligence, though they do not provide the same direct cryptographic assurance as NFC. A hybrid approach combines NFC authentication of the physical document with cloud-based checks for sanctions, fraud indicators, device intelligence, and other risk factors. Didit presents its AI-native modular platform as a way for agencies to build such workflows through NFC verification, ID data extraction, facial and liveness checks, AML screening, and configurable APIs or no-code tools, while advertising free core KYC and no setup fees.
