Abstract
There is provided a communication device including a secure communication unit configured to perform secure communication with an external reader/writer device, the secure communication being secure close-proximity communication, a first communication unit configured to perform high-speed communication with the reader/writer device, the high-speed communication being close-proximity communication that is faster than the secure communication, a second communication unit configured to, when communication via the high-speed communication is disconnected, communicate with the reader/writer device with a communication mode that is different from a communication mode of the high-speed communication, 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. The second communication unit may be configured to, when communication via the high-speed communication is disconnected, operate with the power stored in the secondary battery.
