Program storage and goods information storage equipment facilitate the storing data in non-volatile memory device. When POS terminal (101) start, which is stored in non-volatile memory device (107) with goods information more new equipment operation data compared with and is stored in storage control (121) with data. If it is incorrect or be longer than those and be stored in storage control that the program and goods information are stored in non-volatile memory device, program renewing device and goods information updating device help to read the programme information from storage control and commodity and by the non-volatile memory device of the program of reading and merchandise news. The program executing apparatus executes the program, therefore is stored in storage equipment. One program realizes that described process is stored in the storage medium of data.
