Light enabled RFID card
First Claim
1. A radio frequency identification (RFID) card comprising:
- an antenna configured to transmit data wirelessly to a remote receiver;
an integrated circuit configured to store the data, the integrated circuit being further configured to transmit the data through the antenna to the remote receiver; and
a light-sensitive switch interposed between the antenna and the integrated circuit, the light-sensitive switch configured to allow electrical communication between the antenna and integrated circuit when light is incident on the switch.

Abstract
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.
