The new system, developed by Oberthur Technologies, is called Motion Code, and it changes the security code on the back of the credit card every hour. That way even if a thief does steal the info, it will be useless in less than an hour, preventing nearly all fraudulent transactions.Other than a small screen on the back, the card is identical to the ones you already own. It’s durable and waterproof, and the same size and thickness of a regular credit card. The small lithium battery that powers the screen will last three years, at which point the card will expire.
