Android mDocs Verifier SDK

The Android mDocs Verifier SDK is based on the ISO/IEC 18013-5 standard which establishes an interoperable digital representation of mobile-based credentials such as mobile drivers licenses (mDL). However, this SDK can extend the same technology and architecture to more then just mDLs, but rather any conforming mobile document (mDoc) - a term defined in ISO/IEC 18013-5.

SDK Capabilities

The SDK offers tools to assist developers integrating the following capabilities into their Android applications:

  • Verify an mDoc:
    • Request and verify mDocs via a proximity presentation workflow as per ISO/IEC 18013-5:2021.
    • 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.
