If you're wondering how the privacy advocates that get shipped off to Japan's wireless island will maintain their sanity, we've got a hunch that they just might look Paper Tyger's way before departing. The aptly-named RFID Shield is reportedly "easily printable" and unsurprisingly aims to protect personal information on contactless credit cards and similar wallet mainstays. Purportedly, the unit contains "a new security barrier to assure that sensitive information contained on the card's RFID chip remains protected when not in use," and can even be fabricated into envelopes or paper sleeves. No word just yet on when this here RFID-shunning technology will be available for purchase, but we're sure at least a small sect of individuals will be clamoring for dibs when it finally goes commercial.

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.
