M-Trust SDKs: Integrating with our Hardware Devices

The M-Trust SDKs allow you to integrate our hardware tightly within your mobile applications. The SDKs are available for the SEC-Reader, IMP-Reader.

The SDKs allow you to quickly integrate an identification and verification step into your application.

All pub.dev packages included in the repository.

Cross-Platform Compatibility

The SDKs are optimized for cross-platform mobile development, with support for iOS and Android devices. Built using the Flutter framework, they provide a unified development experience across platforms, simplifying app development and maintenance.

While we recommend to implement your application using Flutter, the SDKs can also be used in native iOS and Android applications by following the native embedding guides provided by Flutter. Depending on the connection strategies you want to enable please make sure to configure the correct permissions:
