ABSTRACT:
The present invention has a cash register1and a Bluetooth portable terminal2which conduct short-range wireless communication to each other. The cash register1decreases transmission power during periods when a search request processing and a connection request processing for the Bluetooth portable terminal2are conducted, thereby being connected with only a prescribed Bluetooth portable terminal2. At the time of providing services, electric power for transmission is increased. Therefore, it is possible to surely connect with the prescribed Bluetooth portable terminal2. After connected with the prescribed Bluetooth portable terminal, even if the Bluetooth portable terminal2moves at comparatively broad range, it is possible to provide the Bluetooth portable terminal2with services.
