Issue and verify a reusable identity credential using ISO 18013-5 mobile driving license and OpenID for Verifiable Presentations

Steps

1. Configure your verifier to support the OpenID for Verifiable Presentations protocol and define the presentation definition specifying which mDL claims are required
2. Generate an authorization request with your verifier's client ID and the presentation definition, and present it to the holder's wallet via QR code or deep link
3. The holder's mDL wallet responds with a VP token containing a signed mDL presentation over the requested claims using device-bound keys
4. Validate the VP token signature against the issuer's public key, verify the device engagement and session transcript binding to prevent replay attacks
5. Extract the disclosed claims from the presentation and verify that the issuer certificate chains to a trusted root in your mDL trust store
6. Apply your business logic on the verified claims (for example, using only the age over 21 boolean claim without receiving the full date of birth) to minimize data collection
