Issues with contact less payments.

[LeGaulois]

In my country, you need to re-enter your PIN each time you've spent 100€. That's the reason I don't like to use, maybe good for the small payments. I know with a Raspberry PI you can make something to collect the card's information from people but here you could do nothing with it since you receive a SMS code from your bank for each online transaction.
People can use card protection like this one, sometimes you can get some for free
