The EU proposed limiting transaction fees to 0.2%. I don't know whether that is ...

0.2% for debit cards, 0.3% for credit cards.

Only applies to consumer cards and only the interchange (ie. the part that the bank of your card gets). MasterCard and Visa fees are still quite substantial.

A regular merchant would now pay < 1%, so quite a bit cheaper than before.

The outcome was that they cut back on lots of loyalty programs, and not many businesses passed on the cost savings to the consumers.

So sounds like limiting the fees had an adverse effect on the consumer.
