Pilot project demos credit cards with shifting CVV codes to stop fraud

US-based PNC Bank is in the middle of a pilot project that aims to test out credit cards with constantly changing card verification values (or CVVs) to reduce online credit card fraud. The dynamic CVV is displayed on the back of such a card in e-ink, and changes according to an algorithm supplied by Visa.

[...] A static CVV number can provide some protection from online fraud, but sometimes CVVs can be stolen in tandem with the card number. Worse, researchers have shown that Web bots making random guesses on legitimate websites can often come up with the appropriate CVV and expiration date to pair with a card number.

A dynamic CVV should—at least in theory—be far more difficult to guess and use. The idea of a dynamic CVV isn't new: the cards are being supplied by a company called Idemia, which announced its "Motion Code" dynamic CVV cards in 2016. Since then, Visa has detailed a specification for the dynamic CVV pairing, called dCVV2, and Visa is also a partner in getting this pilot project off the ground.

    Guessing this concept won't play well with anyone that still pays some bills by mail. Often there is a place to write in the credit card number and security code...which then spends a few days in postal mail before getting to the payee. For example, my dentist still accepts credit cards this way, although I mail him a personal check now (used to use the card to get the float...when inflation was high).
