Abstract: According to one embodiment, a transaction processing system for retail stores that sell optionally deliverable commodities includes a communication network connectable to a mobile user terminal permitting a customer to register items for purchase on a sales floor of a store. A transaction processing server stories commodity codes for items sold by the store. Each commodity code is associated with a deliverable flag indicating whether the item is deliverable. A processor of the server is configured to: determine whether a registered commodity code is a deliverable commodity based on the deliverable flag value associated with the registered commodity code; cause the mobile user terminal to display a decision screen for receiving a selection input from the customer to have the item delivered or not; and register the customer's selection in conjunction with the registered commodity code to permit settlement of the sales transaction including the deliverable commodity.

Abstract: A server device includes a communication interface configured to communicate with one or more publisher devices and one or more subscriber devices. A memory stores data indicating message types to be issued by the publisher devices. Each message type is stored in association with both a condition for filtering messages of the message type and a subscriber device destination for messages of the message type meeting the condition. A processor is configured to determine whether a message meets a condition associated with the message type, and transmit the message to the subscriber devices indicated by the corresponding destination information when the condition is met.

Abstract: An information processing device comprising a processor configured to determine a first timing designated for a product registered as a purchased product. The processor is also configured to determine a first registration position where the product is designated. The processor is also configured to determine a second timing designated for the product. The processor is also configured to determine a second registration position where the product is designated. The processor is also configured to determine, based on the first timing, the first registration position, the second timing, and the second registration position, a first reliability of the first registration position. The processor is also configured to generate first tracking data relating to the product by associating the second timing, the second registration position, and the first reliability.

Abstract: To reduce a load on a client terminal that uses a device under control. A first control unit operates the device in response to a device use request from the client terminal. A detection unit detects a failure of the device. A transfer unit transfers, when a failure is detected in an operating device under control of the first control unit, the device use request from the client terminal to another device control apparatus connected via the network. A second control unit operates, when the device use request is received from the other device control apparatus via the communication interface, the device in response to the request.

Abstract: According to one embodiment, a parking fee management supporting system supports parking fee management concerning a car park in which a free parking available period is granted according to a purchase amount in a predetermined store. The parking fee management supporting system calculates a free parking available remaining time in the car park in association with a user, who inquires about a remaining time of the free parking available period, on the basis of a parking start time and purchase information of the user.
