In the US, often you don't have to put your pin code to use the cards. You can just sign. That helped a lot to fraud the system.

In France for instance, we have to put the pin code unless it's a contacless payment (below 50 euros). It doesn't mean there is no fraud but it's much harder i guess.

What they do here is they put a device in the ATM so when you put your card, the device scan your information and frauders can make a copy of your card. It's known as the "Marseille double" because mobsters from Marseille sort of invented that fraud.
