Communication system, image processing apparatus, server, and computer-readable medium

An image processing apparatus comprising:

• an image processor;
• a communication interface configured to communicate with an external device via an Internet;
• a near-field communication interface configured to perform near-field wireless communication with an external device, using a near-field wireless communication protocol;
• an operation interface;
• and
• a controller configured to:
• accept, via the operation interface, an input of an instruction to perform data communication with a service providing apparatus on the Internet;
• in response to accepting the input of the instruction to perform data communication with the service providing apparatus, transmit communication request information to a server via the communication interface, the communication request information being for requesting the server to perform data communication with the service providing apparatus;
• receive acquisition instruction information from the server via the communication interface, the acquisition instruction information being for instructing the image processing apparatus to receive authentication information, the authentication information representing authorization to perform data communication with the service providing apparatus;
• in response to receiving the acquisition instruction information from the server via the communication interface, set the near-field communication interface into a receivable state where the near-field communication interface is allowed to receive the authentication information from an information processing terminal device;
• receive the authentication information from the information processing terminal device via the near-field communication interface;
• transmit the received authentication information to the server via the communication interface;
• receive communication instruction information from the server via the communication interface, the communication instruction information indicating a method for the data communication with the service providing apparatus;
• and
• in response to receiving the communication instruction information from the server via the communication interface, perform data communication with the service providing apparatus via the communication interface in accordance with the received communication instruction information.

A server comprising:

• a communication interface configured to communicate with an image processing apparatus, an information processing terminal device, and a service providing apparatus via an Internet, the image processing apparatus being configured to perform data communication with the service providing apparatus using authentication information, the authentication information representing authorization to perform data communication with the service providing apparatus;
• and
• a controller configured to:
• receive transmission request information from the information processing terminal device via the communication interface, the transmission request information being for requesting the server to transmit the authentication information;
• in response to receiving the transmission request information from the information processing terminal device, transmit the authentication information to the information processing terminal device via the communication interface;
• receive communication request information from the image processing apparatus via the communication interface, the communication request information being for requesting the server to perform data communication with the service providing apparatus;
• in response to receiving the communication request information from the image processing apparatus via the communication interface, transmit acquisition instruction information to the image processing apparatus via the communication interface, the acquisition instruction information being for instructing the image processing apparatus to receive the authentication information;
• and
• in response to receiving the authentication information from the image processing apparatus via the communication interface, transmit the communication instruction information to the image processing apparatus via the communication interface.

A non-transitory computer-readable medium storing computer-readable instructions that are executable by a processor coupled with an information processing terminal device, the information processing terminal device comprising a communication interface, a near-field communication interface, and a user interface, the instructions being configured to, when executed by the processor, cause the processor to:

• accept, via the user interface, an input of an instruction to perform a preparation process to connect an image processing apparatus with a service providing apparatus;
• in response to accepting the input of the instruction to perform the preparation process via the user interface, transmit transmission request information to a server on an Internet via the communication interface, the transmission request information being for requesting the server to transmit authentication information, the authentication information representing authorization to perform data communication with the service providing apparatus;
• receive the authentication information from the server via the communication interface;
• store the received authentication information;
• and
• transmit the stored authentication information to the image processing apparatus via the near-field communication interface, using a near-field wireless communication protocol.
