| == Device API ==
| |
| There are three layers of device API: C API, JNI API and Java API.<br>
| |
| === Java API ===
| |
| The Java API is packaged as an AAR library file that Android developers can easily use. You can download the latest AAR library file from the link below.

| |
| | |
| === JNI API ===
| |
| The JNI interface wraps the C API to help Java developers use the C API. We recommend that you use the Java API instead of the JNI API.

| *[[How to import JNI to a project]]
| |
| *[[JNI Samples|Samples]]
| |
| | |
| === C API ===
| |
| C API related header files and so libraries have been included in the system. Application developers can create native so libraries through C API to implement their business logic. As a result, the implementation will be more secure than the Java implementation. For example, the EMV library can use the C API.

| === Permissions ===
| |
| To access any financial devices of the terminal, the application must apply the relevant permissions in the manifest file.

| | |
| === Printer Usage ===
| |
| The printer of the terminal supports ESC command. Please refer to the following specifications:
