While we were a bit skeptical when Chase sent us one of their questionably-secure RFID-equipped "Blink" cards last year, we're gonna be all over a new technology from several companies that actually gives credit cards a heigtened level of security by generating a one-time passcode for each transaction, viewable on an embedded e-ink display. The OTP DisplayCard, as it's being called, was developed by InCard Technologies in conjunction with security firm nCryptone using technology from SiPix Imaging and SmartDisplayer, and is being targeted at financial institutions or at other companies as a replacement for the password-generating key fobs used to enable VPN access to their intranets. While the added security feature would come into play for both online and in-person transactions, it will probably be most useful for Internet purchases, making your credit card info almost worthless to identity thieves who can't get their hands on the card itself. Oh, and to answer the inevitable question: no, these cards will not be able to play Doom.
