The test suites are now open for self-certification, giving governments, wallet providers, issuers, verifiers, and technology vendors a mechanism to formally demonstrate that their implementations conform to the specifications. OpenID4VP and OpenID4VCI are specifications for digital identity wallets that have been adopted by more than 30 jurisdictions, including the UK, Switzerland, India, and the EU member states through the EU Digital Identity Wallet programme. Until the conformance programme was completed, organisations could implement the specifications but had no independent, publicly recognised way to verify that their systems met the security requirements or would interoperate with other implementations.
