Abstract
The POS system has at least one POS terminal (101) and a store controller (121) connected to the POS terminal. The POS terminal has a program storage device (107), a program updating device (106), a program executing device (106), a goods information storage device (107) and a goods information updating device (106). The program storage device and the goods information storage device serve to store data in a non-volatile storage device. When the POS terminal (101) is started up, the program updating device and the goods information updating device operate to compare the data stored in the non-volatile storage device (107) and the data stored in the store controller (121). If the program and the goods information stored in the non-volatile storage device is incorrect or older than those stored in the store controller, the program updating device and the goods information updating device serve to read the program and the goods information from the store controller and store the read program and goods information in the non-volatile storage device.
