Introduction to Acceptance Devices | PAX Acceptance Devices App

The PAX Acceptance Devices App enables partners to easily integrate their point-of-sale (POS) systems with supported PAX terminals 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 PAX terminal 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 PAX terminal.

For more information about the modes available in the Acceptance Devices app, see:

Local Mode Payment Services

Cloud Mode Payment Services

Standalone Mode Payment Services

For information about the current version of the Acceptance Devices Android app, see the Release Notes for PAX Acceptance Devices App.
