Privacy-First Age Verification on Android
summary
An EU reference implementation for privacy-first age checks is available as open source: Android/iOS apps plus backend, built on the EUDI wallet libraries and OpenID for VC/VP protocols, using Android Keystore with per-credential keys and device PIN/biometric binding. It issues batches (e.g., 30) of disposable credentials stored as MDOs, presents a single boolean age claim (no name or DOB), supports cross-device QR and same-device flows, runs on 50+ modular repos, is tested in five EU countries and has 100+ GitHub stars.
