An object of the present invention is to enable appropriate switching among a plurality of modes including a cellular communication mode and an RFID information receiving function. A communication system is comprised of an RFID configured to transmit predetermined ID information of its own, a server capable of being connected to a cellular communication network, and an aggregation point for aggregating information from the RFID. In the communication system, the aggregation point, which is comprised of a mobile communication terminal or the like, is provided with an ID receiver for receiving ID information from an RFID, and a cellular communication part for performing cellular communication via the cellular communication network. Furthermore, the aggregation point is provided with a new mode controller for receiving a switching signal for switching among a plurality of modes including the cellular communication mode and the RFID information receiving function from the server, and for performing a mode switching control based on the received switching signal.
