Communication system
A communication system for unmanned stores includes a management server and an access point connected to a communication network. In-store devices are configured to provide information to a system processing device by wireless communication via the access point and each include a first wireless controller for communicating with the access point according to certain parameters and a second wireless controller for directly communicating with the other in-store devices. A processor in an initial setup mode turns on the second wireless controller, determines whether the in-store device is a representative terminal based on information stored in a local storage unit. If the in-store device is a representative terminal, initial setting information is broadcast via the second wireless controller. The initial setting information includes the certain parameters for the other in-store devices. If not a representative terminal, the processor waits for reception of initial setting information.
