Contact/non-contact IC card and contact/non-contact IC card reader-writer
First Claim
1. An IC card comprising:
- a contact for connecting to a contact IC card reader-writer, data communication between the IC card and the contact IC card reader-writer being transmitted through the contact;
a wireless part for performing data communication with a non-contact IC card reader-writer;
a modem for modulating data transmitted to and demodulating data received from a non-contact IC card reader-writer;
a controller for controlling the data communication;
a detector for detecting that the IC card is inserted into a contact IC card reader-writer and for detecting that the IC card is inserted into a non-contact IC card reader-writer; and
a selector for connecting the controller to the contact when the detector detects a contact IC card reader-writer and connecting the controller to the modem when the detector detects a non-contact reader-writer.

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/non-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.

5. An IC card reader-writer comprising:
-
a contact for connecting to a contact IC card inserted in the reader-writer, data communication between the inserted contact IC card and the IC card reader-writer being transmitted through the contact; a transceiver for performing data communication with a non-contact IC card inserted in the reader-writer; a modem for modulating data transmitted to and demodulating data received from an inserted non-contact IC card; and a controller for controlling the data communication; wherein the controller judges if an inserted IC card is a contact IC card and if the inserted IC card is a non-contact IC card, and, based on a judged result, accesses the inserted IC card if the inserted IC card is judged to be a contact IC card or a non-contact IC card. - View Dependent Claims (6, 7, 8)

9. An IC card comprising:
-
a contact for connecting to a contact IC card reader-writer, data communication between the IC card and the contact IC card reader-writer being transmitted through the contact; a transceiver for transmitting data to and receiving data from a non-contact IC card reader-writer; a modem for modulating data transmitted to and demodulating data received from a non-contact IC card reader-writer; a controller for controlling data communications; a detector for detecting that the IC card is inserted into a contact IC card reader-writer by detecting a supply voltage on the contact; and a selector for connecting the controller to the contact when the detector detects a the supply voltage from a contact IC card reader-writer into which the IC card is inserted, and connecting the controller to the modem when the detector does not detect a supply voltage from a contact IC card reader-writer into which the IC card has been inserted.
