PURPOSE: A wireless communication function card is provided to equips an IC card supplying a contactless interface with more NFC(Near Field Communication) and/ or RFID(Radio Frequency ID) tag, thereby using the IC card as a 900MHz bandwidth RFID tag and/ or 13.56MHz bandwidth local area communication method. CONSTITUTION: An IC chip(305) is not directly connected with an antenna for wireless communication. An RF chip(500) processes the wireless communication of the IC chip by connecting with the IC chip and also connecting with the antenna for the wireless communication. An antenna coil layer is equipped with an antenna(110) connected with the RF chip. |
