Use of Credit cards of any kind add an invisible charge to the cost of doing business

And if a customer uses a rewards card, the business pays even more, an extra 1-2%.  Your credit card company crows about their generosity giving you miles or points.  It doesn’t cost them a thing. The merchant pays it.

When I had a merchant account it was against the terms of service to charge any customer more for paying with a credit card (as opposed to cash or check).  Every type of card had this requirement, and it was enforced.  

Some years after that the credit card issuers lost a string of court cases and it was deemed their scheme was illegal.  So now a merchant can tack on the credit card fees if they want to, including charging more for cards that cost them more to process.
