INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING METHOD, INFORMATION PROCESSING PROGRAM, AND RECORDING MEDIUM

摘要

The present invention accepts a reservation, in which the number of days from the reservation day to the usage day exceeds the number of days in a credit period, as the reservation in which a credit card was selected as the method of payment, while ensuring the security of the payment of the usage fees. An information processing device verifies the validity of the credit card when a request is made for a reservation, in which the number of days to the usage day exceeds the number of days in a credit period. If the information processing device was able to verify the validity, the information processing device accepts the reservation and stores the information of the credit card to a storage means. On or after the day in which the number of days until the usage day of the service for which a reservation was accepted becomes equal to or less than the number of days in the credit period, the information processing device verifies the validity of the credit card used when making the reservation on the basis of the information of the credit card stored in the storage means. If the information processing device is not able to verify the validity, the information processing device outputs a set of information indicating that the payment method is changed to a method that is different from the payment method using the credit card.
