<p>A device, system, and method for performing a transaction using a translucent, transparent or semitransparent transaction card with a transaction card sensing device includes a transaction card of a material capable of passing visible light, such as clear PVC, and an infrared filter which is capable of passing visible light while preventing passage of infrared light in a predetermined range of wavelengths emitted by an infrared light source of the transaction card sensing device. When the transaction card is dipped in the card sensing device, the infrared light filter interrupts the passage of infrared light from the infrared light emitting source to an infrared light sensor of the transaction card sensing device, and the infrared light sensor generates a signal indicative of the presence of the transaction card in the card sensing device in response to the interruption.</p> |
