THE MARGIN / Dual Pricing & Surcharging

Dual pricing signage:
what has to be posted, where, and in what size

A dual-pricing or surcharge program isn't legal because the math is right — it's legal because the customer could see the cost before they paid. Here is exactly what goes on the door, the counter, the checkout page, and the receipt, with the actual minimum sizes.

The short answer

Visa's merchant surcharging rules require disclosure at three touchpoints: a sign at every public entrance (minimum 32-point Arial or equivalent), a disclosure at every point-of-sale terminal or register (minimum 16-point Arial), and a notice on the online checkout page if you sell online (minimum 10-point Arial). Every receipt must also show the fee as its own itemized line, never folded into the total. States can add requirements on top of the network rules — New York's General Business Law § 518 requires you to post the credit-card-inclusive total price, not a cash price with a fee bolted on at the register, and caps penalties at $500 per violation. None of this is optional cosmetic detail: undisclosed fees are the single fastest way a compliant-sounding dual-pricing program turns into a chargeback wave, a network audit, or a state complaint.

Merchants get the arithmetic of dual pricing and surcharging right constantly — cap it to cost of acceptance, exclude debit, register with the networks. Then they lose the program on the part that has nothing to do with math: the sign. A fee a customer didn't see coming isn't cost recovery in the eyes of a network auditor or a state regulator — it's a hidden charge, and hidden charges are what surcharging rules exist to prevent. This piece is the signage half of the compliance picture: what has to be posted, exactly where, and in what size, sourced from the network rules and the state statutes that add to them.

The three places you must post a disclosure

Visa's merchant surcharging framework — the rulebook that binds nearly every U.S. surcharge program, since Mastercard's terms are broadly aligned — sets three mandatory disclosure points. Miss any one of them and the program is out of compliance regardless of how correctly you calculated the fee.

A fourth disclosure point sits outside the "signage" category but is just as mandatory: the receipt. We cover it separately below because it has its own formatting rule.

The signage requirement isn't paperwork — it's the thing that turns a legal fee into a legal fee a customer actually consented to.

Minimum sizes, by touchpoint

Visa's guidance gets specific about type size because "post a sign" is unenforceable without one. The figures below are the published floors — treat them as the minimum you can get away with, not a design target. Bigger, higher-contrast, and better-lit is always the safer choice.

Three practical notes that don't show up in the bare numbers:

What the receipt has to show

Every network-compliant surcharge or card-price program requires the fee to appear as its own labeled line on the transaction receipt — separate from the sale subtotal, separate from tax, and never folded silently into a single total. If a customer can't look at their printed or emailed receipt and see exactly what they were charged for paying with a card, the program fails this control regardless of what the signage looked like at checkout. This is usually the easiest piece to configure correctly in a modern POS or gateway — most terminal software supports a dedicated surcharge or "card price" line out of the box — but it's also the piece most likely to silently break after a POS software update, so it's worth spot-checking receipts periodically rather than assuming a one-time setup holds forever.

Where state law adds a second layer

The network rules above are national. State law can add restrictions on top — sometimes on the mechanics of the signage itself, not just whether surcharging is allowed at all. We cover the full state legal landscape (bans, caps, and the contested states) separately in our 2026 surcharging rules guide and state-by-state surcharge laws; the signage-specific wrinkle worth calling out here is New York.

New York General Business Law § 518 doesn't just require a disclosure sign — it requires a different posting mechanic. The statute says a seller imposing a surcharge must "clearly and conspicuously post the total price for using a credit card in such transaction, inclusive of surcharge," and that "the final sales price of any such sales transaction, inclusive of such surcharge, shall not amount to a price greater than the posted price." In practice that means a New York menu or price tag needs to show the card-inclusive number, not a base price with "+3%" appended at the register. New York also permits an alternative two-tier format — posting both the cash price and the card price side by side — which functions differently from Visa's entry-and-POS signage model and has to be layered on top of it, not swapped in for it. Violations carry a civil penalty of up to $500 per instance. (Source: N.Y. Gen. Bus. Law § 518.)

Colorado is a simpler addition: it caps the surcharge itself at 2%, below both network ceilings, but doesn't change the signage mechanic — the entry/POS/checkout/receipt structure still applies, just against a lower number. Massachusetts, Connecticut, Maine, and Puerto Rico enforce outright surcharge bans, which makes the signage question moot there — there's no legal surcharge to disclose. California and Texas both have bans on the books that federal courts have ruled unconstitutional, leaving enforcement inconsistent; if you operate in either, confirm your specific posture with counsel before you post anything, because the signage rules only matter once the underlying legality question is settled.

A worked example: a $12k/mo café going dual-pricing

Consider a single-location coffee shop doing roughly $12,000 a month in card volume, currently on a typical flat-rate processor at 2.6% + 10¢ per swipe, split about 55% debit / 45% credit at the counter, card-present only — no online ordering yet. The owner wants to move to dual pricing: a card price that reflects true cost, and a cash price that's lower. Because this location is card-present only, the signage list is short but non-negotiable: one sign at the single public entrance (32-point minimum), a disclosure at the register — likely a small counter card or a line on the POS screen (16-point minimum) — and a card-price/cash-price line on every printed receipt. There's no e-commerce checkout to worry about yet, but the moment this café adds online ordering, the 10-point checkout disclosure becomes mandatory too. On debit transactions specifically, the shop cannot apply a surcharge at all — only the credit-card portion of that 45% mix can carry a fee, which is exactly the kind of card-type detection point-of-sale software has to get right before day one.

The implementation checklist

Signage compliance is a short, concrete list — it just has to be run in order and re-checked, not treated as a one-time task.

Frequently asked questions about dual pricing signage

What size does a surcharge sign have to be?

Under Visa's merchant surcharging rules, the sign at your point of entry should use at least 32-point Arial (or an equivalent sans-serif) — no smaller than any other signage nearby. At the point of sale, the disclosure needs at least 16-point Arial. An e-commerce checkout notice needs at least 10-point Arial. Treat these as floors, not targets — bigger and more visible is always safer.

Where does dual-pricing or surcharge signage have to be posted?

At every public entrance to the business, at every point-of-sale terminal or register, on the online checkout page if you sell online, and as a separate itemized line on every receipt. A location with two doors needs a sign on both; a counter with three registers needs the disclosure visible at all three.

Do cash discount programs need the same signage as surcharge programs?

A true cash discount posts one card-inclusive price and reduces it for cash, so the signage job is different in form but not in spirit: customers still need to see, before they pay, exactly what each payment method costs. Regulators and networks judge substance over labels, so a program that looks like a surcharge with cash-discount signage does not get the pass.

What has to be on the receipt?

The card fee — surcharge or the card-vs-cash price difference — must appear as its own clearly labeled line item, separate from the sale total, not folded into a single number. This is a Visa and Mastercard requirement everywhere you can legally run the program, and it is usually the easiest control to configure in a modern POS.

Does New York require different signage than the network rules?

Yes. New York General Business Law Section 518 requires the credit-card-inclusive total price to be posted, not a cash price with a fee added at the register, and caps civil penalties at $500 per violation. That is a different posting mechanic than Visa's entry-and-POS signage, so a New York location needs both the network-compliant signage and GBL 518's posted-total-price format.

Key takeaways

  • Visa's merchant surcharging rules require disclosure at three touchpoints — entry (32pt min), point of sale (16pt min), and online checkout (10pt min) — plus a separate itemized line on every receipt.
  • Font-size minimums are floors, not targets; a technically compliant sign that's crowded out by bigger surrounding signage or hung out of eye-line still fails the intent of the rule.
  • States can layer additional requirements on top of network signage — New York's GBL § 518 requires posting the card-inclusive total price, not a base price plus fee, with penalties up to $500 per violation.
  • Signage compliance is not a one-time task — re-audit it on the same schedule you'd use for rate reviews, especially after any POS software update or store redesign.
