Abstract (en)
[origin: FR2770316A1] A card user removes a card from a pocket or case and ambient light is detected by a photodetector. The resultant signal authorizes the operation of the card which may then be used in conventional systems or in a system using the exchange of optoelectronic signals (104) to further validate and protect a transaction
