She has a bill changer that gives gold $1 coins (the Presidential ones). It takes credit/debit cards. "Cents" there is no profit, the state had it arranged so she doesn't have to pay that 3-4% charge. No way we would have any vendors with that crap. You talkin' about a PITA.
My wife is taking on a new account starting July 20. Pretty decent-sized account with a total of 11 vendors. She's thinking about doing credit on them, but, raising the prices a bit to offset the fees. You'd be surprised how much 4% adds up. No LA Purchase, tho.
