Pretty evil! I imagine the card companies have an explicit rule that, in order to accept their cards, a merchant can't charge their users any extra fee? I wonder if some regulation were created that bans rules like that from existence whether this would change tomorrow.

Kroger stopped supporting Visa cards for a minute and I realized that's literally all I carry.

The opposite law already exists in the EU - merchants aren't allowed to charge users extra for card purchases

the intent was to dissalow discrimination cash vs card. i know eu likes that electric payments, it a lot easier to track.

but what with the fees from card a vs card b.

The EU sets limits on card interchange fees.

Suddenly all "reward cards" lost most of their rewards...

Good. They’re a regressive wealth transfer from the poor to the well off.

In the US, this was the subject of a recent class-action suit! https://www.paymentcardsettlement.com/en
