This repository contains two Flutter packages for reading and verifying electronic travel documents (ePassports, eID cards, driving licences) and performing biometric face verification built for the Yivi ecosystem.
A Dart/Flutter library for reading Machine Readable Travel Documents (MRTDs) via NFC. Implements ICAO 9303 with BAC and PACE authentication, reads all standard data groups, and integrates with go-passport-issuer for server-side Passive Authentication and Verifiable Credential issuance.
A Flutter package for face verification and liveness detection. Supports active liveness (gesture challenges) and passive liveness (anti-spoofing + rPPG heart rate), plus face matching against the DG2 photo from the NFC chip. Runs entirely on-device in a background isolate using bundled TFLite models.
The vcmrtd/example app demonstrates the full flow: MRZ scanning, NFC reading, face verification, and Verifiable Credential issuance.
cd vcmrtd/example
flutter pub get
flutter run- go-passport-issuer — backend service for document verification and VC issuance
- GMRTD — Go library for MRTD operations (used by go-passport-issuer)
- Yivi — privacy-preserving identity platform
The vcmrtd package is based on dmrtd by ZeroPass, with significant modifications and improvements by the Yivi team.
