It's faintly irritating that whenever we hear about a commercial product with E Ink technology being introduced, it's usually not an e-book reader. So here we have SiPix Imaging, another expert in developing electrophoretic displays, who announced today that they developed a flexible e-paper display embedded into DisplayCard, a bankcard for secure authentication. SiPix's technology comes in handy because it's flexible, thin, and consumes only little power (as should be expected from e-paper). The card uses One Time Passwords (OTP) to ensure that you can only use a password once and that a discovered password (through crackers, sniffers, loggers) is basically useless. From the
press release:
During an online merchant checkout or home banking login, the cardholder obtains a new, unique number by pressing a button on the card. As prompted, the cardholder then enters the number, proving the presence of the card, and completes the transaction. With the DisplayCard, banks can strengthen online banking sign-on by enabling two-factor authentication.
