Switzerland has interchange fees of 0.4% for consumer credit cards (by contactless, only slightly higher by chip+pin): https://www.visaeurope.ch/content/dam/VCOM/regional/ve/unite..., https://www.mastercard.com/content/dam/public/mastercardcom/.... And yet banks offer 0.33% cashback cards: https://certo-card.ch/one.

And let's not forget that cash acceptance costs an order of magnitude more than this anyway; if anything businesses should charge surcharges for accepting cash, not the other way around, and given the social constraint of no surcharges, cashback is a fair mechanism to reward efficient payment methods.

Only since Wednesday of this week due to COMCO action, so no-one knows if cashback will persist, but it will be a lot less than .33%.

In the EU, it's .5% for cash vs .3% for cards, but the situation falls back into favour for cash once fraud is accounted for.

That Visa fee table is dated July 2023?

Right, but prior to this week, the merchant account providers just raised scheme fees to compensate.
