Communication system, server device used in communication system, communication device, and program for executing communication method of the communication device

摘要

A communication system including a communication device and a server device. In a server device, a communication information memory stores unique information that is information for identifying a second communication device and communication destination information that is information for communicating with the second communication device. In a first communication device, a first server device identification information memory stores server device identification information that is information for accessing to a server device. An input receiver receives the input of unique information. When the input receiver receives the input of unique information, a first communication destination information acquisition unit accesses to the server device identified by the server device identification information, and acquires communication destination information corresponding to the unique information from server device. A first communication unit communicates with a second communication device by using the communication destination information.
