What South Carolina merchants need to know
South Carolina places no state-level restrictions on credit card surcharges. Merchants are free to pass processing costs to customers who pay by credit card, subject to the card network rules that apply everywhere: the fee can't exceed your actual cost of acceptance (practically capped at 3% if you accept Visa), it applies to credit cards only, and it must be disclosed before the customer pays — at the door, at the register, and on the receipt.
The bigger compliance risk in SC isn't state law — it's implementation. The most common violations we see on merchant statements are surcharges applied to debit transactions (prohibited everywhere) and flat-fee 'non-cash adjustments' that exceed the merchant's actual processing cost on small tickets. Both can get a merchant flagged by the card networks regardless of what state they're in.
The cash discount alternative
Wherever surcharge rules get complicated, dual pricing doesn't: posting a card price and offering a discount for cash is legal in all 50 states when it's structured correctly — the posted price must be the card price, with cash receiving a true discount. The economics match a surcharge; the compliance profile usually beats it.
SC merchants who serve price-sensitive customers often prefer a cash discount program because the posted price already includes the cost of acceptance — no separate fee line for customers to react to at checkout.
