Abstract:
1. A communication device comprising: a close-proximity communication unit configured to perform a low-speed close-proximity communication with an external reader/writer device; a first communication unit configured to perform high-speed close-proximity communication with the reader/writer device, that is faster than the low-speed close-proximity communication; a second communication unit configured to, in response to a negotiation request from the reader/writer device when disconnection of communication via the high-speed close-proximity communication is detected at the reader/writer device, negotiate for medium-range communication and perform the medium-range communication with the reader/writer device; a power transmission unit configured to receive power transmitted from the reader/writer device by power transmission; and a secondary battery configured to store the power received by the power transmission unit, in which the second communication unit is configured to, when communication via the high-speed close-proximity communication is disconnected, operate with the power stored in the secondary battery, and in which the medium-range communication corresponds to a communication mode that is different from that of the high-speed close-proximity communication and from that of the low-speed close-proximity communication, such that the communication device is configured to perform three different types of communication.
