Introduction to Acceptance Devices | Tap to Pay on Android Acceptance Devices App

The Tap to Pay on Android Acceptance Devices App enables partners to easily integrate their point-of-sale (POS) systems with supported Android devices in a semi-integrated manner using Local and Cloud modes. Leveraging the Acceptance Devices Android app and using API requests, your POS system can accept payments by communicating with the Android device over a local Wi-Fi network or the cloud.
The solution can also be operated in Standalone mode. This mode does not require integration with a POS system and enables you to start transactions directly from the Android device.
For more information about the modes available in the Acceptance Devices app, see:
For information about the current version of the Acceptance Devices Android app, see the Release Notes for Tap to Pay on Android Acceptance Devices App.
