In France we mostly use debit cards and they are given for free from the bank. If you buy groceries, it's better to have a smaller amount of money not to bother cashiers. And if you buy big stuff, it's easier with a debit card. Going to an ATM all the time is annoying, and someone can mug you and steal your money.
I'm only listing positive things obviously, but it's to show that no one really cares about the private aspect of banknotes.
