Google makes a quarter of its money by watching where you go and what you do on the Internet, and then serving you ads that it thinks you'll be interested in. Now, credit card companies want to do the same kind of thing, using all the information they have about you, and everything that you buy. Goodbye, privacy.
If you're carrying more than one credit card in your wallet, you're now officially carrying too many. A company called Dynamics has come up with a single credit card that can reprogram itself to be any card you want it to be.
Forever worried about evildoers stealing your credit card? A new kind of card that hides your account info unless you punch in a code is designed to put those fears to rest.
