A radio frequency identification (RFID) card having an antenna configured to transmit data wirelessly to a remote receiver and an integrated circuit configured to transmit the data through the antenna to the remote receiver. The integrated circuit includes a transmitter section and a memory section. The memory section is configured to store the data. A power generating device is configured to supply power to the integrated circuit and a light-sensitive switch is interposed between one or more portions of the RFID card. The light-sensitive switch is configured to provide electrical coupling between the one or more portions of the RFID card when light is incident on the switch.

Light enabled RFID card

A method for imaging a fingerprint on an optical memory card having an upper transparent cover, a base and optical medium therebetween, wherein a cardholder imprints a fingerprint having a pattern of ridges and valleys on the upper cover of the card and a laser beam is scanned over the fingerprint. The laser beam is selectively transmitted by the fingerprint. The laser beam burns pits into optical medium areas corresponding to valleys of the fingerprint and is prevented from burning pits into optical medium areas corresponding to the ridges, thus producing a fingerprint image comprising light and dark areas in the optical medium corresponding to the pattern of ridges and valleys of the user's fingerprint.
