Steps
Build a DigitalCredential request specifying the requested mDL data elements using the OpenID4VP request format
Invoke Credential Manager's digital credential request flow from your verifier app, prompting the user's wallet to select a matching credential
Receive the OpenID4VP response containing the mdoc presentation from the user's chosen wallet app
Validate the mdoc's issuer and device signatures per ISO 18013-5 before trusting any extracted data elements
Extract only the specific requested elements (e.g. an age-over assertion) for your onboarding decision
Known gotchas
The credential exchange depends on OpenID4VP support in both your verifier request and the user's wallet app — older wallet apps that don't implement this presentation protocol will not respond
A successful data return does not imply the license is unrevoked — signature validation only proves data integrity and issuer authenticity at capture time, not current revocation status
Requesting elements not actually needed for your use case adds unnecessary data handling exposure and can trigger stricter consent prompts to the user
