Device API

There are three layers of device API, C API, JNI API and Java API.

C API

The C API offers header files definition and the relevant so library is already included in the system. The application developers can create the native so library by the C API to implement their business logic. So the implementation will be more secure than Java implementation. For example, the EMV library can use C API.

• API Spec
• Error code
• Header files

JNI API

The JNI interface wrappers the C API to help the Java developer to use C API.
Now we recommended you to use Java API instead of JNI API.
