Title:
ICチップ及び情報処理端末
Document Type and Number:
Japanese Patent JP3617491
Kind Code:
B2
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.
