Information processing method, information processing system, and ordering device

An information processing system, comprising:

• one or more ordering devices used for placing a purchase order;
• one or more display terminals;
• and
• a server capable of connecting to the one or more ordering devices and the one or more display terminals, wherein
• each of the one or more ordering devices is without a display and a speaker and includes:
• a memory that stores order information indicating the purchase order and destination information for the server;
• a button that, in response to being pressed, issues an ordering command for transmitting the order information to the server;
• and
• a first interface that transmits the order information to the server in response to the ordering command,
• each of the one or more display terminals includes:
• a display;
• a second interface that receives message information indicating acceptance of the purchase order indicated in the order information from the server;
• and
• a first controller that, when the message information has been displayed on the display, causes status information indicating that the message information was displayed on the display to be transmitted to the server through the second interface,
• the server includes:
• a third interface that receives the order information indicating the purchase order from an ordering device, the ordering device being one of the one or more ordering devices, the one or more ordering devices being different than the one or more display terminals;
• and
• a controller that:
• receives the order information indicating the purchase order sent from the ordering device;
• determines that a display terminal corresponding to the ordering device from which the order information has been sent exists using first information which indicates one or more correspondences between the one or more ordering devices and the one or more display terminals,
• receives, from the corresponding display terminal, first router information identifying a router to which the corresponding display terminal is connected;
• determines that the first router information matches second router information identifying a router to which the ordering device is connected based on second information which indicates routers to which the one or more ordering devices are connected;
• in response to determining that the display terminal corresponding to the ordering device exists and the first router information matches the second router information, transmits message information indicating acceptance of the purchase order to the corresponding display terminal;
• receives, from the corresponding display terminal, status information indicating that the message information was displayed on the display of the corresponding display terminal;
• in response to receiving the status information, starts countdown of a cancellation period which is a cancellation available time for the purchase order;
• and
• sends, to the corresponding display terminal, a request to display a remaining time before the cancellation period is over according to the countdown.

An information processing method for use in an information processing system that is connected with one or more ordering devices used for placing a purchase order and one or more display terminals each having a display, the information processing method comprising:

• receiving order information indicating a purchase order from an ordering device, the ordering device being one of the one or more ordering devices, without a display and a speaker, and including a button that places the purchase order in response to being pressed, the one or more ordering devices being different from the one or more display terminals;
• determining that a display terminal corresponding to the ordering device from which the order information has been sent exists using first information which indicates one or more correspondences between the one or more ordering devices and the one or more display terminals;
• receiving, from the corresponding display terminal, first router information identifying a router to which the corresponding display terminal is connected;
• determining that the first router information matches second router information identifying a router to which the ordering device is connected based on second information which indicates routers to which the one or more ordering devices are connected;
• in response to determining that the corresponding display terminal exists and the first router information matches the second router information, placing the purchase order;
• transmitting message information indicating acceptance of the purchase order to the corresponding display terminal;
• receiving, from the corresponding display terminal, status information indicating that the message information was displayed on the display of the corresponding display terminal;
• in response to receiving the status information, starting countdown of a cancellation period which is a cancellation available time for the purchase order;
• sending, to the corresponding display terminal, a request to display a remaining time before the cancellation period is over according to the countdown;
• and
• canceling the purchase order in response to receiving, from the corresponding display terminal, a request for cancellation of the purchase order during the cancellation period.
