PROBLEM TO BE SOLVED: To make it possible to simply use service based on security information.SOLUTION: A communication system of the present invention comprises a first communication device and a second communication device which is connected to a network and can communicate with the first communication device, where the first communication device uses service in the network through the second communication device. The first communication device comprises: an imaging unit; a communication interface unit for communicating with the second communication device; and a control unit which makes the imaging unit perform imaging when receiving, as input, information on imaging a code picture obtained by encoding security information on utilization of service through the second communication device, reads out the security information included in the code picture imaged by the imaging unit and stores the security information, and transmits a request for utilizing service based on the stored security information to the second communication device through the communication interface unit when receiving, as input, information on utilization of the service in the network through the second communication device. |
