CONTACTLESS CARD INCLUDED SWITCH

摘要

A contactless card is provided to enhance control in using the contactless card by embedding a switch for keeping a short or open state of the contactless card, and to prevent communication cross by enabling a user to conveniently select and use only the desired card in a contactless mode when a plurality of cards are held in a bag or a wallet. An IC chip(203) stores data and performs an operation function. An RF(Radio Frequency) antenna(202) communicates with an RF reader by electrically connecting to the IC chip through an electric signal path. A switch(206) supplies an electric contact signal to the IC chip. The IC chip connects or disconnects the electric signal path to/from the RF antenna according to the signal pattern of the electric contact signal received from the switch. The RF antenna transmits the data to the RF reader by electrically connecting to the IC chip when the electric signal path is connected, and transmits no data by electrically disconnecting from the IC chip when the electric signal path is disconnected. A PSU(Power Supply Unit) receives power from the RF reader through the RF antenna.
