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. The server device has a communication information storage unit for storing unique information used to identify a second communication device and communication destination information used to communicate with the second communication device. In a first communication device, a first server device identification information storage unit stores server device identification information used to access the server device. An input reception unit receives input of unique information. When the input reception unit has received input of unique information, a first communication destination information acquisition unit accesses the server device identified by the server device identification information and acquires communication destination information corresponding to the unique information from the server device. The first communication unit communicates with the second communication device by using the communication destination information.
