A cash register that uses Android OS to run in-store support applications capable of collectively managing data on sales, customers and appointments. It is also highly expandable, linking with order entry systems or EFT terminals for more efficient store operation. Whereas conventional cash registers feature separate touch screen monitors, main processors, customer display units and printers, this product integrates them all into a single compact unit. This concentrates all its operations into a single system and allows it to be integrated seamlessly into any in-store layout – key attributes in a cash register.
