The image forming apparatus converts connection information for connecting to the image forming apparatus by a WLAN scheme into a corresponding image pattern, and displays the image pattern on a display unit. A communication terminal photographs the image pattern displayed on the display unit by a camera. The communication terminal restores the corresponding connection information from the image pattern photographed by the camera, and generates NDEF data based on the restored connection information. The communication terminal writes the generated NDEF data to the NFC tag by NFC communication. ## Claims ### Claim 1 A communication system including a printing apparatus, a mobile terminal, and a Near Field Communication (NFC) tag, wherein the printing apparatus comprises: a first display that can display information;
