While early “clear” payment cards encountered operating problems with ATMs, 3M this week unveiled the first truly transparent, fully ATM-functioning payment card. The new infrared “Vikuiti Clear Card Filter” passes all international standards for payment cards. VISA International recently approved 3M as a manufacturer of a transparent inlay for use in VISA-branded payment cards worldwide. Although the magnetic stripe shows through the front of the card, it can easily be integrated into the design. Typography, solids, patterns, illustrations all reproduce well on the clear plastic substrate and it accepts traditional four-color printing in addition to a wide range of translucent inks. The card is powered by a proprietary multi-layer, IR light-blocking optical film from 3M. Laminated between two clear sheets of PVC, the film reflects the IR light generated by LEDs used in ATMs to detect the presence of a card.
