NEW YORK – With all the talk of EMV lately, people may be inclined to think that the “new” (to the U.S.) technology will put an end to card fraud. Of course, we know that without use of PIN, EMV is only half the solution. In fact, the credit card of the future could go well beyond the current technology, using a constantly changing code to make fraud almost impossible.

A French company, Oberthur Technologies, is testing prototypes for just such a card. The standard-sized card features a mini ink screen powered by a lithium-ion battery (like that in a phone) the size of a postage stamp, designed to last three years. A computer chip in the card randomizes the number every 40 or 60 minutes. The constantly changing code renders the card useless to anyone who has written down your credit card number, expiration date and the code on the back.

"The hope here is that the dynamic CVV will severely cut down on fraud," Martin Ferenczi, Oberthur's top executive in North America, told CNN Money.

Of course, there is a downside: Each card is 50 times more expensive than magnetic stripe cards and still 10 times more expensive than the newer EMV cards that banks have begun issuing. Oberthur plans to sell these dynamic CVV cards for $10 to $20 each, compared to the $1.20 or so that chip cards currently cost.

According to Ferencz, the reduced fraud costs and minimized headache to customers is worth it in the long run, along with the cards added feature that allow it to be used much like a mobile device for payments. Oberthur will be trying to convince banks to upgrade their cards and if the banks are interested, the cards could be available as early as 2017, according to CNN Money.
