The rules you must follow
Card network rules set the baseline in every state: Visa caps surcharges at 3% or your actual processing cost, whichever is lower; you must notify your processor and the card networks 30 days before you start; disclose the surcharge at the point of entry and the point of sale; show it as a separate line on the receipt; and never surcharge debit or prepaid cards.
South Dakota cap: Your cost, up to 4%.
The alternative most merchants use: dual pricing
Dual pricing (also called cash discounting) shows two prices, a card price and a lower cash price. Because it is structured as a discount for paying cash, it is legal in all 50 states, including South Dakota. See the South Dakota dual pricing guide.
