NFC Technology Β· Cryptographic Identity

The passport chip is a
government-signed cryptographic proof.

Every biometric passport issued since 2006 contains an NFC chip with the holder's data, signed by the issuing government's private key. WeVerify reads and verifies this signature, producing identity assurance that no forged document, AI-generated image, or synthetic identity can replicate.

How NFC verification works

Cryptography, not cameras.

WeVerify verification flow
01
Chip detected
The phone's NFC reader detects the chip in the passport. Authentication begins without the user needing to do anything beyond holding the document to the phone.
02
Data extracted
Chip data is read: name, date of birth, document number, expiry, issuing country, and the biometric template stored by the issuing government.
03
Signature verified
The issuing government's signature on the chip data is verified against the public key infrastructure. Forged or altered chips fail this step, immediately.
04
Proof issued
A cryptographic proof of the verified identity is issued. No image is stored. Only the proof travels to WeVerify's platform, the biometric stays on device.

Coverage & compatibility

190 countries. Every major document type.

Passport coverage

All ICAO 9303-compliant biometric passports from 190+ countries including all EU member states, UK, US, Turkey, UAE, Saudi Arabia, and most of Africa and MENA.

National ID cards

NFC-enabled national ID cards including EU national IDs, Dutch DigiD-linked cards, German Personalausweis, French Carte Nationale d'IdentitΓ©, and equivalent documents across Europe.

Residence permits

Biometric residence permits issued in EU member states including the UK BRP. Commonly used for verifying non-EU nationals working in regulated industries.

Device compatibility

Works on NFC-enabled Android devices (Android 8.0+) and iPhone 7 and later. No special hardware required. The standard smartphone NFC reader is sufficient.

No app required

NFC chip reading requires the WeVerify Identity Wallet app, available for iOS and Android. The app acts as a reusable identity wallet: verify once and reuse across multiple services without re-verification.

GDPR-safe architecture

No biometric image is captured, transmitted, or stored by WeVerify. The chip data is processed locally on the user's device. Only the cryptographic proof result reaches the WeVerify platform.
