POS system, an optical reader, and an information processing system

摘要

A POS system comprises a host computer providing a centralized control over a plurality of scanners, and a printer for printing a batch setting bar code or the like. A CPU of the scanner reads the changes in the setting from its own memory when it receives a first transmission request command and then transmits the data to the host computer as a first batch setting data. From this first batch setting data, a first batch setting bar code is generated. When this first batch setting bar code is read using the reader of the scanner whose setting has not been changed, the setting in the memory of this scanner is changed to the setting represented by the first batch setting data. Thus, setting in a plurality of scanners can speedily and accurately be changed.
