A communication system includes a first communication device and a second communication device. The first communication device includes a first near field communication part, a state detection part, and a first control part. The first control part, based on the state of the device itself detected by the state detection part, selects an output pattern for signals output from the first near field communication part and controls the first near field communication part so as to output signals of the selected output pattern. The second communication device includes a notification part, a second near field communication part, a memory, and a second control part. The second control part identifies the state of the first communication device corresponding to the pattern of the received signals, and provides notification of the identified state of the first communication device via the notification part. |
