Installing an Android Application on Debug PAX Devices

PAX devices that are ordered from Visa Acceptance Solutions to debug your application, display the DEBUG only Not for COMMERCIAL
watermark on the bottom-right corner of the device screen.

Follow this step to install an Android application on a debug PAX device.

Connect the PAX device to your computer using the USB cable provided with the device.

Depending on your development tool or operating system, use one of these methods:

If you are using Android Studio, you can install the Android Package Kit (APK) file directly on the PAX device.

Alternatively, you can transfer the APK to the test device, by selecting the file on the device, and then following the instructions to install it.

If you are using an Apple computer, you can use a file transfer tool, such as Android File Transfer, to copy the APK file to the PAX device. Choose the APK file on the device and follow the on-screen instructions to install the file.

If you are using a Windows computer, you can copy the APK file to the PAX device. Choose the APK file on the device and follow the on-screen instructions to install the APK file.
