I’ve been waiting many years for the point where e-paper becomes an actual consumer-ready product and not just a cool idea seen only in a laboratory or the occasional tech demo. Well with devices like Sony’s E-Reader almost/eventually upon us I’m starting to get excited about what other cool applications and ideas we’ll be seeing.
One of those ideas comes from a couple of companies called SiPix and SmartDisplayer who’ve created the first flexible e-paper based display to be built into a plastic credit or debit card. The ‘One Time Password’ Display Card allows the user to generate a dynamic unique passcode for one-time use. During an online transaction the cardholder can press a button on the card to generate the unique number which when entered on the website they’re making a purchase from proves they have the actual card in hand. While it doesn’t stop people from stealing and using your card, it will prevent people from making purchases when all they have is your credit card number.
The best part is the e-paper used in the card will be mass produced by SiPix and made available to banks and other card manufacturers by years end.
