A merchant searching for a "POS with no processing fees" usually means one of two things: a cheaper processor, or a way to make customers pay the fee. Both exist. The second is governed by card-network rules and, in some states, by statute, and it is the one that gets merchants fined. This page reads Visa's own surcharging documents, New York's statute and the POS vendors' documentation, all on October 27, 2026. It is not legal advice; state law on surcharges has changed often.

For whom: a US merchant that wants customers to cover card costs. Not for: merchants outside the United States.

Two ways to pass on the cost

SurchargeCash discount
What the customer seesA card price built from your price plus a fee at checkoutOne posted price (the card price), or card and cash prices side by side; paying cash costs less
Cards it can apply toCredit only; debit and prepaid cannot be surchargedAny card, because there is no added fee
Visa rulesNotify your acquirer 30 days ahead; disclose at the store entrance and at the point of sale; itemize the surcharge on the receipt; no more than your cost of acceptance and never above 3%Prices must be shown as the card price or as both prices; a final card total built by adding a fee may be treated as a surcharge
State lawProhibited or regulated in some states (below)Not covered by the state list below; New York expressly allows two-tier pricing; check your state

The states

Visa's own Q&A, dated February 15, 2024, says Visa understands that Connecticut, Maine, Massachusetts, Oklahoma and Puerto Rico prohibit surcharging, and that Colorado, Minnesota, New Jersey and New York regulate it. Visa adds that this understanding may contain errors and is not legal advice, so read it as a list of places to check, not a final answer.

New York is the clearest example of regulation. General Business Law § 518 requires a seller that surcharges to clearly and conspicuously post the total price for paying by credit card, keeps the surcharge at or below what the card company charges the business, still allows two-tier cash and credit pricing, and sets a civil penalty of up to $500 per violation.

A merchant with stores in several states follows each store's state law, according to Visa: you may surcharge in one state and not in another.

What the POS does for you

POSSurcharge support, per its own documentation
SquareBuilt in for U.S. sellers (open beta); capped at 3% of the total; credit cards only, with ACH, debit, tips, offline and split-tender payments excluded; not available to businesses in Connecticut, Maine, Massachusetts or Puerto Rico; you must display surcharge notices
CloverClover configures the surcharge rate when it onboards the merchant (most U.S. merchants at 3.00%); applied only to eligible credit cards, not debit or cash; offered in U.S. states without legal restrictions
HelcimFee Saver: a 3% surcharge on in-person credit card payments on its Smart Terminal, switched on by the merchant; debit cannot be surcharged; not available in Connecticut, Colorado, Maine, Massachusetts or Oklahoma. Online, Fee Saver works as a convenience fee instead. Its base pay-as-you-go rate is interchange plus 0.40% plus a per-transaction fee in person

Our pick

Square's built-in surcharge, for a small merchant who has decided to surcharge. It enforces the 3% ceiling, skips debit and the other excluded payments automatically, and blocks the feature in the states it names, which removes the mistakes Visa fines acquirers for. You still owe the signage and, under Visa's rules, the 30-day notice to your acquirer, and you still need to check your own state.

  • Pick Clover's program instead if you are already on Clover: the rate is set by Clover at onboarding rather than by you, which keeps it within the program's rules.
  • Look at Helcim instead if your real goal is paying less: its interchange-plus pricing passes the network's cost through with a published markup, which may cost less than a flat rate depending on your card mix and ticket size (check it against a recent statement), and if you still want to surcharge, its Fee Saver does it on the Smart Terminal. Lowering the base rate needs no signage, notice or state check; Fee Saver does. See POS with no monthly fee for the full comparison.
  • Who should not surcharge: a merchant in a prohibiting state, a merchant whose customers mostly pay by debit (the surcharge cannot apply), and any business where an itemized fee at checkout would cost more goodwill than it recovers. A cash discount priced at the card price is the simpler alternative.
