EU law has regulated the maximum fee down to 0.2% for debit and 0.3% for credit cards since 2015, I don't know if it has further progressed since then. But regulation is clearly needed, since these "taxes" on transactions create an inefficient market and they want to encourage, not discourage card transactions. It should be down to the level already that the big stores think that card handling is cheaper than handling cash.
