  • Patent number: 10929565
    Abstract: A memory region on an IC card has a hierarchical structure. Each application allocated on the memory region is registered in a directory, and the memory region is managed in directory units. A personal identification code is set for each application and directory, and the access right is controlled in application units or directory units. If a mobile terminal is lost, the right to access each application in the IC card automatically disappears. Therefore, the right to access each application allocated to the memory region on the IC card is efficiently controlled.

  • Patent number: 7821322
    Abstract: A semiconductor integrated-circuit device rectifies a received carrier wave, generates a first power-supply voltage based on the rectified output, and selects, as a power-supply voltage required for operation, one of the first power-supply voltage and a supplied second power-supply voltage. The first power-supply voltage is selected as the power-supply voltage required for operation when the second power-supply voltage is lower than a threshold value. The second power-supply voltage is selected as the power-supply voltage required for operation when the second power-supply voltage is equal to or higher than the threshold value and an instruction to operate in accordance with a predetermined function is given.

  • Patent number: RE45205
    Abstract: When an IC card is passed over an external card reading and writing apparatus, the IC card starts communication with the card reading and writing apparatus via a wireless interface, so that a change in the internal state of the IC card is reported to an external device via an external wired interface or a dedicated control signal line, thus allowing a specific application to be enabled on the external device or allowing a controller to be powered on and activated. Alternatively, the controller is powered off and deactivated. Accordingly, processing according to the communication state between the IC card and the card reading and writing apparatus or the internal state of the IC card can be smoothly initiated.
