PURPOSE:To improve the work efficiency of a POS system by dividing plural groups of data totalized by plural terminal devices into those of high urgency and low urgency based on a request of a host device and then transmitting them. CONSTITUTION:Plural sleeves POSSP-SPN are controlled by a counter CTR according to an accurate account sending request signal *1 and a divided accurate account starting signal *3 from a master POSMP, and data of high urgency, such as totalized data D1, D2 of total amount sold are sent to MP successively through a driver DRV. In this case, divided accurate account flag is set, and SP1-SPN check the flag at the starting of work next morning, and the remaining totalized data such as amount sold DN of each commodity etc. is sent to MP. Then, the divided accurate account flag is reset. By this way, the futile working time of operators can be reduced and the work efficiency of the POS system can be improved. |
