mDocs Verifier Mobile SDK
The mDocs Verifier SDK are based on the ISO/IEC 18013-5:2021 and ISO/IEC 18013-7:2025 standards, which establish an interoperable digital representation of mobile-based credentials such as mobile drivers licenses (mDL). However, these SDKs can extend the same technology and architecture to more than just mDLs, but rather any conforming mobile document (mDoc) - a term defined in ISO/IEC 18013-5.
The mDocs Verifier SDKs are available for React Native, iOS, and Android. They help developers add mDocs verification capabilities to their apps, allowing secure and privacy preserving verification of presented mDocs in various interoperable workflows.

SDK Capabilities
The mDocs Verifier SDKs offer tools to assist developers integrating the following capabilities into their applications:
- 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.
- 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.

System requirements
The SDK is developed in the Swift programming language and is meant for integration into iOS applications developed in Swift and/or Objective-C. Specifically, it currently only supports applications developed in iOS 15 and above.
While the SDK functionalities are only available for devices from iOS 15 and onwards, the minimum deployment target is currently set to iOS 13. This enables clients to support users up to iOS 13, as long as the SDK is not initialized.
This SDK is developed in the Kotlin programming language and is meant for integration into Android applications. It currently supports Android 7 (API level 24) and above.
This SDK is meant for integration into React Native applications using React Native 0.73 and above. Supported operating systems are:
- iOS 15 or higher.
- Android 7 or higher.
While the SDK functionalities are only available for devices from iOS 15 and onwards, the minimum deployment target is currently set to iOS 13. This enables clients to support users up to iOS 13, as long as the SDK is not initialized.
