Abstract
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.

Claim 1
Independent Claim
132 words
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.
Claim 2
Dependent Claim
132 words
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.
Claim 3
Dependent Claim
33 words
An IC card according to claim 1, further comprising: a rectifier for rectifying a supply voltage received from a non-contact IC card reader-writer to produce a predetermined driving voltage for the IC card.
Claim 4
Dependent Claim
39 words
An IC card according to claim 2, wherein the selector connects the modem with the controller when the detector does not detect a supply voltage, and connects the contact with the controller when the detector detects a supply voltage.
Claim 5
Dependent Claim
29 words
An IC card according to claim 1, wherein the detector is connected with the contact and the detector detects a supply voltage supplied from a contact IC card reader-writer.
Claim 6
Dependent Claim
130 words
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.
Claim 7
Dependent Claim
130 words
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.
