The device in the picture looks more than interesting. It’s an all-in-one credit card concept that can replace all your current plastic cards. The One Card Electronic Card comes with a memory card slot that will let you upload all the details of the various credit cards you might own. And the turning knob lets you choose what card to use on your next purchase. The screen shows you exactly the copy of the real card and it even displays the back of the card on the other side. Once a payment is completed the receipt is safely stored on your memory card and you won’t have to deal with paper receipts again.

When will we see it in action? Will it be safe enough to be accepted by banks? Will hackers be able to get all your private information stored on the virtual credit cards? These questions will be answered once the concept becomes a real product. And there’s no telling if the One Card Electronic Card will ever be made!
