Abstract:
A smart card having a multi-layer substrate; a transponder module disposed in a first layer of the multi-layer substrate; a first antenna disposed in the first layer of the multi-layer substrate; and a second antenna disposed in a second layer of the multi-layer substrate. A switch and a capacitor in series with the second antenna. The first antenna may be tuned to a different frequency than the second antenna. An RFID chip and antenna in a mold mass disposed in a recess in the first layer of a substrate, behind a hologram disposed on the first layer of the substrate. The switch for the second antenna disposed under the RFID chip. A layer of ferrite material disposed between the hologram and the RFID chip. LEDs disposed behind the hologram.
