Introduction to Acceptance Devices \| PAX All-in-One Android Solution {#pax-aio-intro} ====================================================================================== The Acceptance Devices \| PAX All-in-One Android Solution enables you to integrate your point-of-sale (POS) system directly with supported PAX terminals in an all-in-one configuration.
