Abstract: Improvements in the accuracy of position measurement based on a result of distance measurement using a phase-based method or distance measurement using a communication device are disclosed. In one example, an information processing device includes determination processing that determines, based on reliability information on distance measurement or position measurement obtained by performing communication processing for distance measurement using a phase-based method with a selected communication device, whether or not reselection of a communication device to be used for position measurement is required or whether or not to perform distance measurement using a method other than the phase-based method.

Abstract: A wallet server includes a processor with hardware. The processor is configured to acquire user information of user terminals carried by users who use a store, and configured to perform payment processing, and to generate group information when payment processing is performed by using a first user terminal. The group information is user information of the first user terminal and a second user terminal. The processor is configured to generate, from information on the payment processing and the group information, consumption information associated with each of the user terminals in a group.

Abstract: In a wallet server including a processor having hardware, the processor acquires image information that includes a captured image of food provided to a user transmitted from a store terminal of a store providing the food, and user information related to the user provided with the food, and associates the acquired image information with the user information and transmits a display instruction to instruct display of the image information and a screen for accepting input of evaluation for the food to a user terminal of the user determined based on the user information.

Abstract: A processor provided with hardware is provided. The processor acquires user information of a plurality of the user terminals output from a store terminal that is provided in a store and executes payment settlement processing, generates, when a predetermined user terminal among the user terminals executes the payment settlement processing, group consumption information based on group information containing the user information of the predetermined user terminal and the user information of the other user terminals and consumption information associated with each of the user terminals contained in the group information, and generates payment information containing an allotted amount of the predetermined user terminal with respect to a target user terminal based on the group consumption information. The payment information contains information on a user ID of the predetermined user terminal, user IDs of the other user terminals, and the allotted amount.

Abstract: A processor provided with hardware and a memory storing group consumption information containing group information containing a plurality of pieces of user information of a plurality of user terminals and consumption information associated with the group information are provided. The processor acquires notification information for performing notification about a store externally, retrieves the group consumption information based on the user information of the user terminals constituting a group, selects the notification information from the acquired notification information based on the retrieved group consumption information, and outputs the selected notification information.

Abstract: A wallet server includes a processor provided with hardware. The processor acquires traffic information including a content related to a traffic condition in association with movement of a moving body that a user is on board from a traffic information server that provides the traffic information, weather information including a content related to weather in association with the movement of the moving body from a weather information server that provides the weather information, and payment settlement information including a content related to payment settlement of the user from a facility terminal installed in a facility, and calculates a reward for the user based on at least one of the payment settlement information, the traffic information, and the weather information.

Abstract: A wallet server includes a processor having hardware. The processor is configured to acquire additional information including content to be provided to a user from a plurality of settlement service provider servers configured to provide a plurality of different settlement methods, acquire user information regarding the user from a user terminal carried by the user, select at least one settlement method among the plurality of different settlement methods based on at least one kind of information of the additional information and the user information, and transmit the at least one selected settlement method to the user terminal.
