Overview
A driver licence credential is issued to a wallet. When age verification is required, the holder discloses only the 18+ proof, not their address or licence number.
Why it matters
Many age checks over-collect data. Selective disclosure protects privacy while still delivering strong assurance to retailers and venues.
Ecosystem roles
- Issuer: Transport authority or motor registry.
- Holder: Driver.
- Verifier: Retailer or venue.
Assurance and lifecycle
The licence Verifiable Credential supports revocation and expiry checks. Verifiers confirm issuer trust and status before accepting proof.
