Card Service

TCardService provides basic card reading and pinpad functionality via providing AIDL interface. It is a BoundedService, which is only active when another application is bounded.

Integration

Download the zip file below and extract it.

Place the cardservicebinding-release.aar library file into your project's "libs" folder and add it as dependency inside your app level build.gradle file like below and build your project in order to create build classes of library.

dependencies { implementation fileTree(dir: 'libs', include: ['*.aar']) ... }
