J.G.
They go through as any Visa card would and merchants have been charged a fee since credit cards began.
So pretty much these fees have been used to allow banks to offer services that otherwise would require fees or minimum balances. The merchants complained that these high fees, like 15 to 25 cents, were being passed on to consumers that used the cards through a small markup in the price of goods.
Congress in their infinite wisdom says hey we can't have that and capped the fees at I think 5 cents. Brilliant so now all the services that were offered by the bank using that fee will now be charged or some are just charging the difference directly to the consumer when the card is used.
I think someone needs to put up a huge banner in both charmbers of congress that says there is no such thing as a free lunch!
