ABSTRACT:
An IC card capable of being operated with both a contact IC card reader-writer and a non-contact IC card reader-writer, and an IC card reader-writer capable of operating with both a contact IC card and a non-contact IC card. The IC card includes a contact for connecting to a contact IC card reader-writer, a transceiver for communicating with a non-contact IC card reader-writer, a modem for use with a non-contact IC card reader-writer, a CPU for controlling data communication, a detector for detecting whether the IC card is inserted in a contact IC card reader-writer or a non-contact IC card reader-writer, and a selector. The selector connects the contact with the CPU if the detector determines that the IC card is inserted in a contact IC card reader-writer, and connects the modem and the CPU if the detector determines that the contact
on-contact IC card is inserted in a non-contact IC card reader-writer. The reader-writer includes a contact for communicating with a contact IC card, a transceiver for communicating with a non-contact IC card, a modem used with a non-contact IC card, and a CPU. The CPU determines the type of inserted IC card and the reader-writer accesses the card accordingly.
