Method for managing authority to enter for a power supply vehicle

A method performed by an information processing apparatus that comprises a controller, a memory, and a communication interface and manages authority to enter one or more locations, the method comprising:

• storing, by the controller in a database in the memory, location admission information indicating whether each of the one or more locations has a restriction on entering;
• receiving, by the controller via the communication interface, a notification that a reservation for use of a charging service has been made by a user who uses a location among the one or more locations, the charging service being a service in which a power supply vehicle charges a user vehicle at the location;
• temporarily granting, by the controller, first authority to enter the location to the power supply vehicle in a case in which the location admission information indicates that a restriction on entering the location is provided by a device installed at an entrance of the location;
• receiving, by the controller via the communication interface, first identification information associated with the first authority granted to the power supply vehicle when the power supply vehicle enters the location;
• causing, by the controller via the communication interface, the device to permit the power supply vehicle to enter the location based on the first identification information;
• and
• in a case in which payment of a fee is required upon entering or exiting the location, charging, by the controller, a first amount of the fee to the user vehicle and a second amount of the fee to the power supply vehicle, the second amount being lower than the first amount,
• wherein the first identification information includes a unique ID and password assigned to the power supply vehicle or a provider of the charging service.
