VeriSign has already teamed up with PayPal to offer one-time use passwords on key fobs, but it looks like it's now found a way to make that additional layer of protection even more portable, partnering with Innovative Card Technologies Inc. to squeeze the disposable digits onto standard size bank cards. Apparently, you'll get a new password after each transaction you make online (displayed by pushing a button on the back of the card), making it theoretically impossible for anyone without the card to access your account, even if they somehow manage to get a hold of your regular password. While it's not clear when the cards will actually be put into use, VeriSign is promising to make an announcement about a "major bank" set to use the cards sometime this month.
