Forget fraud, Société Générale and Groupe BPCE's new bank cards are about to change everything about fraud.

Part of the problem is that once your card details are stolen – whether through a phishing attack or by someone copying the digits on the back – fraudsters are free to go on a spending spree until you notice something's up.

They're getting away with millions, and it's a problem affecting over half a million people in the first half of 2016 alone.

Normally by the time you get around to actually cancelling your card, it's all too late. But what if the numbers on your card changed every hour so that, even if a fraudster copied them, they'd quickly be out of date?

That's exactly what two French banks are starting to do with their new high-tech ebank cards.

On the back of each card is a 3 digit security number which you must quote to validate any online or telephone purchase. If this number is compromised then there is nothing to prevent the card being used by anyone else. But on the new card the digits are displayed on a small LCD 7-segment display:

The three digits on the back of this card will change, every hour, for three years. And after they change, the previous three digits are essentially worthless, and that's a huge blow for criminals.

Providing that you still have the card in your possession, then whoever has access to the current security number has less than 1 hour to make use of the card. No details are given on how the card issuer and businesses keep synchronised with the current valid card number.

    I have faith in the hacking community and you know that'll be built to traditional infosec security standards so about 5 minutes after they deploy your talking cereal boxes they'll be powned and displaying 4chan memes to little old ladies. I kinda like that idea.
