    摘要： 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.

    摘要： 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.

    摘要： An IC card transmits data received from a card reading and writing apparatus to a portable terminal via an external interface without changing the received data, or after the received data is converted according to an appropriate conversion scheme or is converted into other packet data. Conversely, the IC card transmits data received from the portable terminal via the external interface to the card reading and writing apparatus via a non-contact interface without changing the received data, or after the received data is converted according to an appropriate conversion scheme or is converted into other packet data. Therefore, non-contact data communication can be performed between the information processing terminal connected to the IC card and the card reading and writing apparatus.

    摘要： A shaped-wave application section inputs a first pulse signal corresponding to transmission data output from a transmission data output section, and applies, to a modulation and amplification section, a signal wave corresponding to a second pulse signal such that the waveform of the first pulse signal is shaped. The pulse signal applied to the base of the transistor of the modulation and amplification section is amplitude-modulated into an amplitude-modulated wave in which the amplitude-modulated portion is strengthened, in accordance with the signal wave corresponding to the second pulse signal applied to the emitter thereof. The amplitude-modulated wave is supplied to an antenna section including a resonance circuit via the collector thereof, and is transmitted as an electromagnetic wave from the antenna section.

    摘要： An antenna unit prevents a communication error by suppressing side lobes formed by an antenna coil segment of a reader/writer device. The antenna unit (200) is used for a reader/writer device (20) whose signal processing circuits (210) and (220) communicate with an IC card (10) via electromagnetic waves, wherein an antenna coil (100) of the IC card (10) relatively gets close to the antenna unit (200). The antenna unit (200) includes the antenna coil segment which forms a loop antenna (202) on a substrate (201) and conductor segments (203) at the periphery of the antenna coil on substantially the same plane of the antenna coil.
