In some situations, there is an allowance to demand a surcharge for accepting a card. It comes with very narrowly standardized rules, because it basically is supposed to be "exactly the cost to accept the card".

From what I've seen it turns into a compliance mess outside of in-person retail, because many states have regulations and gimmicks on top of it, and the system will end up kicking out a rejection code if you ask for the wrong amount, or on the wrong customer. It's obviously intended that you just bake the cost in for everyone because that avoids people blaming the card networks for higher prices.

The only time I've seen it in person was when I went to make the initial payment on an auto lease; the dealer had a sign up saying that there would be a 3% credit surcharge, which exceeded the 2% cash back I expected from Citibank, so I used a debit card instead.
