Abstract

An information system comprises a card and a card reader. The card and the card reader can be coupled by an optical communication module and an optical power transfer module. Operations of the card can be powered by the power transferred from the card reader through the optical power transfer module. In one embodiment, the card and the card reader comprise multiple cells of transmitter/receiver that transmit and receive data in a parallel manner

Claims

1. An information system comprising:

a. a card;

b. a card reader;

c. an optical communication module for transferring data between the card and the card reader, wherein said optical communication module further comprises a plurality of transmitters and a plurality of receivers in the card and in the card reader, wherein said plurality of receivers receive data from said plurality of transmitters in a predetermined parallel manner; and

d. an optical power transfer module for transferring power from the card reader to the card for powering operations of the card when the card and the card reader are coupled.

2. The system as recited in claim 1, said card further comprises a plurality of cells, wherein each of the cells further comprises a transmitter and a receiver.

3. The system as recited in claim 1, wherein said card reader further comprises a plurality of cells, wherein each of the cells further comprises a transmitter and a receiver.

4. The system as recited in claim 1, wherein said card reader further comprises an open slot for receiving said card.
