Researchers in the Netherlands propose technologies to enhance credit card and ID security

Credit cards with magnetic strips are old hat. IBM first engineered the technology in the mid 1960s and it’s been the standard ever since, but the industry is really starting to evolve. We’ve seen services like PayPal, Square, Venmo and Apple Pay take off and now, the physical credit cards are due for a makeover.

Researchers at P.W.H Pinkse and the University of Twente in the Netherlands have devised what they believe to be a better solution for preventing forged or counterfeit credit cards using principles derived from quantum physics. It’s called quantum security authentication technology and here’s how it works. Instead of a magnetic strip, credit cards would have a thin white strip of nanoparticles painted on one end of the card. When banks want to assign the card to a specific person, they would use a laser to bounce light across the strip and leave unique identification marks much like a fingerprint.
