It used to be the case that the credit card companies put language in their merchant agreements language requiring the merchant to change the same price for credit and cash transactions. I'm not sure how many places they just lost the leverage to do that sort of thing and how many places enacted legislation to prevent that kind of strong-arming.
In the US, those merchant agreements were invalidated as of 2011 via the Dodd-Frank financial reform legislation.
