A smart credit card could communicate directly with banking institutions.
A lot of the new technology on display at this year's Consumer Electronic Show is far from actually reaching the market. But one piece of tech, a reprogrammable payment card, will definitely be coming to U.S. banks soon, according to Mashable.
Currently dubbed Wallet Card, it's a collaboration between Dynamics Inc. and Sprint. It can be used for a variety of accounts, including debit, credit and loyalty cards.
The card itself looks like a standard credit card, but it has a small e-ink display and two buttons—like a miniature Nintendo Gameboy.
Inside the Wallet Card is a cellphone chip that would let it communicate directly with the bank. This feature is useful for card replacements, downloading new security information or locking an account in case of a breach.
Don't worry about changing batteries or charging the wallet card, either. It contains a small organic chip that allows it to recharge itself.
