Louisiana Just Put a $500 Penalty on a Card Fee Most Small Businesses Don't Know They're Charging
Somewhere in the last few years, a lot of small businesses added a line to checkout: a "card processing fee," a flat 3%, a toggle their point-of-sale vendor turned on during a rate hike. Most owners never looked past the total number. Fewer checked whether that fee applies the same way to a debit card as it does to a credit card. That gap just got more expensive to ignore.
The rule you may have already broken
Card networks have long drawn a hard line between credit and debit. Merchants are generally allowed to add a surcharge on credit card transactions, within limits and with required disclosure. Debit cards are a different story: surcharging a debit transaction, even one run through a credit terminal or signed instead of PIN-entered, is against Visa and Mastercard's own merchant rules. That's a contract term between a business and its payment processor, not a law, so for years the only real consequence was a processor flagging the account. Most point-of-sale systems that auto-apply a blanket "card fee" don't stop to ask which kind of card the customer tapped.
Louisiana just turned that into a state law violation
Louisiana Governor Jeff Landry signed SB 254 into law as Act 751 on June 2, 2026. It takes effect August 1, 2026, meaning it's already the law in Louisiana today. The new statute bars retailers from imposing a surcharge specifically on debit card payments and backs it with real teeth: a cardholder has to give written notice first, and if the business doesn't cure the violation and reimburse the customer within 30 days, the Louisiana Attorney General can pursue a civil penalty. That's a state regulator now enforcing, directly and separately from the card networks, a rule most small businesses assumed was only a processor's problem.
North Carolina has its own bill moving
If you run a business in North Carolina, there's currently no state statute governing card surcharges either way, which is exactly the gap Louisiana just closed for itself. House Bill 13, filed in the current session, would change that here too. As summarized by the UNC School of Government's Legislative Reporting Service, the bill would cap credit card surcharges at 2% of the transaction and require clear disclosure to the customer, both online and at checkout. Versions of the bill have also addressed debit surcharges directly. It hasn't passed yet, and the exact scope has shifted between drafts, but the direction is the same one Louisiana already took: more states are deciding this needs a statute and a penalty, not just a card network's fine print.
What to actually check this week
You don't need a lawyer to do the first pass yourself. Pull up your point-of-sale settings or ask your processor directly: does the surcharge program distinguish debit from credit, or does it apply the same fee to every card swipe, tap, and insert? A lot of default configurations on common POS systems apply one flat fee to all card types unless someone goes in and turns on the debit exemption. If yours does that, you're exposed to exactly what Louisiana just started enforcing, and potentially to whatever North Carolina or another state does next.
This is the kind of thing that's easy to fix once you know to look, and easy to keep breaking if nobody's job is to check it. It's also a decent example of where a monitoring agent earns its keep: reading your processor's settings and statements on a schedule, flagging a mismatch like an all-cards surcharge, and routing it to you to confirm before anything changes. The agent reads and proposes. You approve what actually gets switched.
