Abstract

Abstract A prepaid card management system includes a memory and a determining unit. The memory causes a card to store a fixed card number together with value information and stores the value information and the card number in correspondence with the value information when a service is finished. The determining unit stops a service when value information read out from the card upon starting of a service is larger than the value information read out from the memory in correspondence with the card number.
