PURPOSE: A functional display type radio frequency identification (RFID) card is provided to confirm balance information through a balance display device, thereby easily supplying a money supplement time to a user. CONSTITUTION: A control unit (32) is equipped with one side of an upper side of a base sheet. The control unit receives balance information, which is outputted from an RFID tag (13), and converts the balance information into number information. A liquid crystal display unit (33) displays the number information. A battery (34) supplies driving power to the control unit and the liquid crystal display unit. A loop antenna is equipped with a bottom surface of the balance display device. The loop antenna drives the RFID tag by generating the induced electromotive force when the loop antenna accesses to a terminal. A protective sheet (14) and a transparent film sheet (17) laminated on the upper side of the base sheet comprise through-holes (14a,17a) which exposes the liquid crystal display unit. |
