COMBI CARD AND COMMUNICATION SYSTEM USING THEREOF

摘要

PURPOSE: A combi card and a communication system using the same are provided to effectively protect information of the combi card. CONSTITUTION: In a combi card(1000), a transponder chip module in which an RF(Radio Frequency) antenna is formed is attached to a recess groove of a card main body. A card reader(400) performs communication using a carrier of a fixed frequency to read data from the combi card. In an amplification sheet(300), a coil amplifying the carrier is formed. A combi card communication device prevents disable communication extending the communication distance between the combi card and the card reader.
