According to the present invention, disclosed is a sticker having a light emitting device using induced electromotive force of a near-field communication (NFC) frequency. The sticker comprises: a thin metal plate having an installation hole; a flexible printed circuit board (FPCB) including an induction coil for an antenna to transform, into electric energy, an electromagnetic wave transmitted from a terminal capable of performing contactless wireless communication by electromagnetic induction effect and a light emitting diode outputting light by the electric energy generated in the induction coil, so as to be placed and installed in the inside of the installation hole of the thin metal plate; and an adhesive part installed on the other surface of the thin metal plate and the FPCB. The installation hole of the thin metal plate has an opening part opened to one side in order to prevent interference with respect to an electromagnetic wave received in the induction coil by the thin metal plate. According to the present invention, since the sticker is formed in a thin metal plate type, the appearance of the sticker is enhanced and high quality as an accessory is added. Moreover, since the opening part is formed on the thin metal plate, the interference with respect to the electromagnetic wave received in the induction coil is prevented even if the sticker is formed in the thin metal plate type, and thereby the electromagnetic wave is easily received without the interference. |
