Communication system for performing wireless near field communication in which image processing apparatus transmits connection destination information to portable terminal

A communication system comprising a portable terminal, an image processing apparatus, and a server,

• wherein the image processing apparatus comprises:
• an image processor configured to form an image;
• a first communication interface configured to communicate with the server via the Internet;
• a first near field communication interface configured to perform wireless near field communication with the portable terminal according to a prescribed protocol;
• and
• a first controller configured to:
• transmit service request information to the server via the first communication interface, the service request information including request for a service provided by a service providing apparatus;
• receive transmission instruction information from the server via the first communication interface, the transmission instruction information including an instruction to transmit connection destination information via the wireless near field communication, the connection destination information being for specifying a connection destination;
• and
• transmit the connection destination information to the portable terminal via the first near field communication interface in response to establishment of wireless near field communication between the first near field communication interface and the portable terminal,
• wherein the portable terminal comprises:
• a second near field communication interface configured to perform wireless near field communication with the first near field communication interface according to the prescribed protocol;
• and
• a second controller configured to receive the connection destination information from the image processing apparatus via the second near field communication interface,
• wherein the server comprises:
• a second communication interface configured to communicate with the first communication interface via the Internet;
• and
• a third controller configured to:
• receive the service request information from the image processing apparatus via the second communication interface;
• and
• transmit the transmission instruction information to the image processing apparatus via the second communication interface in response to reception of the service request information from the image processing apparatus.
