  • Patent number: 11055696
    Abstract: A portable terminal, a terminal function management system, and a terminal function management method that can prevent electronic money fraud by another person after loss or theft and readily and accurately determine the electronic money balance to be guaranteed are provided. In a portable terminal, a lock function that imposes restrictions on access to a chip storage unit that stores a value balance is enabled. It is thereby possible to prevent electronic money fraud by another person after the loss or theft of the portable terminal. Further, in the portable terminal, a value balance acquired after the lock function is enabled and before the lock function is released is stored in an electronic money server. It is thereby possible to readily and accurately determine the electronic money balance to be guaranteed which is stored the chip storage unit at the time when the loss or theft is found.

  • Patent number: 7703672
    Abstract: An internet N is connected to an electronic money management server 10 so that communications can be performed with a deposit money terminal device 30 replenishing an electronic money for an user card comprised by recording a card ID and an issuer ID, a member shop terminal device 50 reducing the electronic money utilized from the user card, and the like. The electronic money management server 10 acquires the deposit money amount and the issuer ID from a deposit money terminal device 30 at the replenishment time of the electronic money, and totalizes the deposit money amount for each issuer, and performs the delivery of the cash for the totalized deposit money amount to the issuer.

  • Patent number: 6789166
    Abstract: A specific-accessible service and a commonly accessible service can co-exist while ensuring the security thereof. It is assumed that a common area of a company A's issued IC card has registered therein an electronic value (corresponding to 1000 yen and a specific area thereof has registered therein a specific-accessible service point of 50 (corresponding to 50 yen). With respect to the commonly accessible electronic value and specific-accessible service point that are registered in the enterprise A's issued IC card, addition and subtraction can both be executed using a specific key A registered in the company A's terminal apparatus. However, in each of the respective cooperating companies' terminal apparatus, with respect to the commonly accessible electronic value, only subtraction processing is possible using a common key registered therein.
