Verifier Mobile SDKs Overview

• Interface with an mDoc holder to request presentations of issued mDocs via:
  • Proximity verification: Verify an mDoc presented in-person as per ISO/IEC 18013-5:2021.
  • Remote mobile app verification: Remotely verify an mDoc presented from a different app installed on the same mobile device (as per ISO/IEC 18013-7:2025 and OID4VP).
• Manage a list of trusted issuer certificates which presented mDocs can be validated against.
• Manage status lists which can be used to check mDocs' revocation status.
