    摘要： An IC card has a card information memory area wherein there are written a master public key nA, card secret keys pU and qU, a card public key nU, a card identification number IDU, and a first master digital signature SA1 for information including the card identification number. An IC card terminal has terminal information memory area wherein there are written a master public key nA, terminal secret keys pT and qT, a terminal public key nT, a terminal identification number IDT, and a second master digital signature SA2 for information including the terminal identification number IDT. When inserted into the IC card terminal, the IC card sends thereto the data nU, IDU, and SA1. The IC card terminal verifies the digital signature SA1 by the master public key nA and, if it is valid, transmits the data nT, IDT and SA2 to the IC card. The IC card verifies the digital signature SA2 by the master public key nA and, if it is valid, transmits information corresponding to the current remainder value V to the IC card terminal. The IC card terminal makes a check to see if the received information corresponding to the remainder value V is appropriate, and if so, becomes enabled for providing a service.

    摘要翻译： IC卡具有卡信息存储区域，其中写有主公开密钥nA，卡秘密密钥pU和qU，卡公开密钥nU，卡标识号IDU和用于包括卡的信息的第一主数字签名SA1 识别号码。 IC卡终端具有终端信息存储区域，其中写有主公开密钥nA，终端密钥pT和qT，终端公钥nT，终端标识号IDT和第二主数字签名SA2，用于包括终端的信息 识别号码IDT。 当插入IC卡终端时，IC卡向其发送数据nU，IDU和SA1。 IC卡终端通过主公开密钥nA验证数字签名SA1，如果有效，则将数据nT，IDT，SA2发送给IC卡。 IC卡通过主公开密钥nA验证数字签名SA2，如果有效，则向IC卡终端发送与当前剩余值V相对应的信息。 IC卡终端进行检查以查看与余数值V对应的接收信息是否合适，如果是，则能够提供服务。

    摘要： In the subject magnetic card, first magnetic recording layer 2 is laid over substrate 1. First magnetic recording layer 2 has a coercive force that enables magnetic recording of data. Second magnetic recording layer 4, having a coercive force smaller than that of first magnetic recording layer 2, is laid over first magnetic recording layer 2, with shielding intermediate layer 3 interposed therebetween. Magnetic shielding layer 5 is provided as an uppermost magnetic layer.
