The Mobile POS is a simplified POS terminal that has a local database on the mobile device, containing the full item master as well as all other data necessary to drive the supported retail features.
The application functions in online mode only through a Real-time connection to the back-end system available either through Wi-Fi or a means provided by the cellular network (3G/4G). The application supports complex prices and discounts via a web service call to the back-end system, accessing a transaction calculation service which returns a fully calculated transaction, including tax group break-down information.
