The Mini Wallet as a Building Block of Interoperable Wallet-Based Age Verification
summary
A working Android pilot shows a streaming app gating an FSK16 film by asking the OS to call installed wallets, offering a choice between Google Wallet and a U ID mini wallet on the same device; issuance happens from a bank app into either wallet, authentication via fingerprint/face, and the relying party receives only a binary over-16/over-18 signal with no DOB. Implementation uses the W3C Digital Credentials API plus OpenID for VP/VCI and adds zero-knowledge proof, and the demo succeeds end-to-end.
