Abstract: PURPOSE: A system and a method for the electronic payment using a non-contact electronic cash IC card are provided to carry out a payment transaction with various kinds of non-contact electronic cash IC cards with only one SAM(Secure Application Module). CONSTITUTION: The non-contact electronic cash IC cards(300,301) different with each other are issued from a different electronic cash company and a different card issuance company. A reader(200) recognizes the IC cards and communicates with the IC card. The SAM(100) stores a key set by dividing into each electronic cash company, carries out the mutual certification with the IC card by using the stored key set, and stores the transaction price information of the IC cards.

Abstract: PURPOSE: A method for managing and controlling an entitlement in a chargeable broadcasting system for supporting various pay-view services is provided to classify a series by setting a proper theme ID and an event ID when a qualification managing message is created. CONSTITUTION: A key ID(21) is used for a cryptography of a plurality of information(22, 23, 24, 25, 26). Mask information(22) is a value for deciding an application range of a theme ID(23) and an event ID(24). The mask information(22) is identified with the sum of sizes of two fields. EXTM information(25) indicating an expiration time is used for deleting a qualification record exceeding to the time from a memory by an interior operation of a smart card. DUR information(26) is valid only in the case of a PPP service. The information from the mask information(22) to the DUR information(26) means a watching right of each member. If the corresponding qualification is valid, the information is stored in a card memory. In the case of a PPE(pay-per-event), the total value of the theme ID(TID)(23) and an event ID(EID)(24) becomes a valid program ID. In the case of a PPS(pay-per-series), the DUR information(26) is ignored and a bit calculation logical value of the mask information(22) and the theme ID(TID)(23) become a series. In the case of a PPP(pay-per-period), a user can watch from a starting time of watching of a chargeable program to a time passed for the DUR, and if the smart card receives a qualification managing message, one's expiration time is changed into a time adding the current time to the DUR, and thus the corresponding service is possible.
