Abstract
Order information indicating a purchase order is received from an ordering device. Whether a display terminal corresponding to the ordering device from which the order information has been sent exists or not is determined using information which indicates correspondences between ordering devices and display terminals. Message information indicating acceptance of the purchase order indicated in the order information is transmitted to the corresponding display terminal. It is determined whether status information indicating that the message information was displayed on the display of the corresponding display terminal has been received from the corresponding display terminal or not. A cancellation period during which a process for canceling the purchase order indicated in the order information is accepted is started upon reception of the status information.
