Passport

A passport is a government-issued travel document that proves a person’s identity and nationality. Modern e-passports embed a secure NFC chip storing biographical and biometric data that must conform to ICAO 9303. Physical pages include anti-counterfeiting features (watermarks, holograms, microprinting), while the machine readable zone (MRZ) enables automated checks.Because passports are standardized and security-hardened, they’re widely accepted as primary ID in KYC worldwide. Institutions verify data consistency (photo, name, number, DOB, nationality), check expiry and tampering, and, where permitted, validate chip signatures. As a high-assurance credential, the passport anchors remote onboarding, cross-border finance, and travel, but must be paired with liveness/ownership checks to prevent impersonation.
