As you probably guessed, this is just concept. In fact, it's downright Technology Minority Report.

It's Live-checking card that physically the amount of ad spending on the card after each purchase.

The display is powered by e-Ink technology and uses to sync with your bank account RFID.

So, if you do not make a purchase, sure you can afford, easy to use to see your card before you buy.

Honestly, I'm not sure that this is a good thing, if a thief were suddenly “buy” the card. Many would probably be a thief, the motivation to buy a few things.

In some ways reminds me of Chase Mastercard commercial where the guy takes MasterCard and uses it as if it were some sort of device for mobile augmented reality.

In other words, if we have a wireless card in order to save the expenses on the card, we can do if the card can make a check / savings transfers, pay bills, and other account activity online?

Yes, I think there must be a use for it, but I'm sure there are at least five years. However, if this card will be implemented the act, then I think all the banks to their customers should be asked that cardholders.
