RF ID CARD

摘要

PURPOSE: An RF(Radio Frequency) ID card is provided to maximize an AD(ADvertisement) effect due by enlarging large lighting area by making a front surface of an EL(Electro Luminescence) sheet emit light when the RF ID card faces to a terminal. CONSTITUTION: An EL sheet power supply layer(26) is equipped with a loop antenna(23) inducing DC power when communicating with the terminal, and an inverter(25) converting the DC power by connecting to the loop antenna(23). A light emitting layer(21) attaching the EL sheet(22) lighted by the output power of the inverter(25) and installed to a position matched with the AD surface(16) is installed to an upper side of the EL sheet power supply layer(26). The loop antennas(12,23) are deposited by using a conductive ink.
