In my eyes it's useless circulation of money in the best case (when recouping via kickback) and a tax on the financially illiterate or poor in the worst case. In any case it is creating a lot of expensive administrative overhead for no economic purpose whatsoever, and thus a healthy capitalistic society should want to get rid of it - which is even relatively easy to do in this case, as the European regulation demonstrates.

Does that also allow merchants to put an additional surcharge depending on the card used onto a receipt? Or has that been deemed legal in an earlier ruling? Because I always thought the big card networks had some kind of legally binding contract with merchants which prohibits the addition of surcharges that only apply to their particular payment method - contract clauses that they could only muscle through because merchants effectively didn't have the possibility to just not accept Visa or MasterCard payments, while most of their competitors accepted them.
