The EU regulates credit card fees caping them at 0.3% [1]. That is roughly a fifth of the fees charged in the US and roughly two orders of magnitude smaller than Apple app store fees.

I think that’s a different fee. As a merchant accepting credit card or debit card payments is going to cost you the same 2-3%. At least that’s what Stripe or local payment processors charge

Stripe charges 1.5% + €0.25 ($0.27) in the EU to accept EEA cards [1]. Stripe charges 2.9% + $0.30 for processing domestic cards in the US [2].

The reason it charges 1.4% more for accepting US cards is the US card fees (interchange fees). These fees are complicated and roughly five times more than European card fees [3].

It varies state-to-state.

And yet several places do. “Menu reflects cash prices” and “tuition payment via credit card will be subject to a 3.5% fee” are 2 I got this week.

What? Basically every store I go to adds a fee for credit transactions.

The typical way stores get around it in Canada is with a "discount" if you pay cash.
