A POS fee is a charge that shows up when you pay with a card at a register, terminal, or checkout screen, and it can come from your bank, the merchant, or the card network. Some POS fees are a few cents per transaction. Others run 1% to 3% of the purchase. A handful are illegal in your state. Knowing which kind you’re looking at tells you whether to shrug it off, switch payment methods, or dispute it.
Who Actually Charges the Fee
Three parties touch every card payment: the bank that issued your card, the merchant’s bank, and the payment network such as Visa or Mastercard. Each takes a small cut. The merchant usually absorbs the bulk of that cost through what’s called an interchange fee, paid to your card-issuing bank.
Merchants don’t always eat the full expense. Some pass a portion back to you as a surcharge at checkout. Your own bank may also charge you separately for certain transaction types, and that charge appears on your statement independent of the purchase price. So a “POS fee” on your account can mean two very different things: a fee the merchant added to your total, or a fee your bank quietly tacked on for the way you paid.
The POS Fees You’ll Actually See
PIN Debit Fees
When you select “debit” at a terminal and enter a PIN, the transaction routes through a different network than if you select “credit” and sign. Roughly 15% of debit card customers pay per-transaction fees on PIN-based purchases, compared to about 1% who see fees on signature-based debit transactions.1Federal Reserve Bank of Chicago. Chicago Fed Letter, No. 221, December 2005 – Debit Card Competition: Signature versus PIN If your bank is one that charges for PIN debit, pressing “credit” and signing on a debit card purchase sidesteps the fee.
Foreign Transaction Fees
Buying from a merchant outside the United States triggers a foreign transaction fee that covers currency conversion and cross-border screening. These typically run 1% to 3% of the purchase. It doesn’t matter whether you’re standing in a shop overseas or ordering from a foreign website at your kitchen table. Some banks and card issuers waive foreign transaction fees on specific card products, so it’s worth checking your card terms before a trip or a big international order.
Surcharges
A surcharge is an extra fee a merchant adds because you paid with a credit card. It can only be applied to credit card transactions, not to debit or prepaid card purchases. Visa caps surcharges at 3% of the transaction or the merchant’s actual processing cost, whichever is lower.2Visa. U.S. Merchant Surcharge Q and A The merchant has to tell you about the surcharge before you pay and list it as a separate line on your receipt.
Convenience Fees
A convenience fee applies when you use a non-standard payment channel, such as paying a utility bill online or over the phone when the biller’s default is mail or in-person. Convenience fees can apply to any payment method, not just credit cards. They may be a flat dollar amount or a percentage. Government agencies commonly charge around 2% when you pay taxes or fines by card.
Surcharge vs. Convenience Fee
People use these terms interchangeably. They aren’t the same, and the difference decides whether the charge is even legal.
A surcharge targets the payment type (credit card). A convenience fee targets the payment channel (paying online instead of in person). Surcharges are banned outright in several states, capped by network rules, and restricted to credit cards. Convenience fees carry far fewer restrictions and can attach to any form of payment.
A store that adds 3% because you paid with a Visa credit card instead of cash is charging a surcharge. A water department that adds $3.50 because you paid on its website instead of mailing a check is charging a convenience fee. Figuring out which one you’re looking at tells you whether you can push back on it.
Finding the Fee on Your Statement
Banks label these transactions with shorthand: “POS Debit,” “POS Purchase,” or an alphanumeric code followed by the merchant name. The fee itself may be baked into the transaction total, which hides it unless you match your receipt against your statement. Sometimes it posts as a separate line item a few days after the purchase.
Turning on real-time transaction alerts in your bank app is the fastest way to catch surprises. At the end of the month, scan your statement for charges that don’t match your receipts. A small mismatch usually points to either a bundled surcharge or a bank-imposed transaction fee.
What the Law Limits
Federal Disclosure Rule
Starting in May 2025, the FTC’s Rule on Unfair or Deceptive Fees requires certain businesses to display the total price upfront, more prominently than any other pricing information. When a business adds a credit card surcharge and offers no reasonable fee-free payment alternative, the surcharge has to be folded into the displayed total. When a fee-free option does exist, the surcharge still has to be disclosed clearly before payment and included in the final amount charged. Online, these disclosures must be “unavoidable” and can’t be hidden behind a hyperlink or buried in fine print.3Federal Trade Commission. The Rule on Unfair or Deceptive Fees: Frequently Asked Questions
State Surcharge Bans
Federal law doesn’t ban credit card surcharges outright, but some states do. Eleven states and Puerto Rico prohibit merchants from adding surcharges to credit card transactions: California, Colorado, Connecticut, Florida, Kansas, Maine, Massachusetts, New York, Oklahoma, and Texas.4National Conference of State Legislatures. Credit or Debit Card Surcharges Statutes If you live in one of those and a merchant tacks a credit card surcharge onto your bill, the charge likely violates state law. Card networks also require merchants to disclose any surcharge at the store entrance, at the terminal, and on the receipt. A surcharge with no prior disclosure can be reported to your card network.
Debit Interchange Cap
The Durbin Amendment, part of the Dodd-Frank Act, limits what banks with more than $10 billion in assets can charge merchants to process debit card transactions.5Federal Reserve Bank of Richmond. Did the Durbin Amendment Reduce Merchant Costs? Evidence from Survey Results Smaller banks and credit unions are exempt, which is one reason your POS fee experience can differ depending on who issued your card.6Office of the Law Revision Counsel. 15 USC 1693o-2 – Reasonable Fees and Rules for Payment Card Transactions
SNAP and EBT
Federal law prohibits interchange fees on SNAP purchases made with an EBT card.7Office of the Law Revision Counsel. 7 USC 2016 – Issuance and Use of Program Benefits Neither card networks nor banks can charge retailers a swipe fee on SNAP transactions, and the 2018 Farm Bill extended the ban to state-side processing fees. No POS fee should appear on a SNAP transaction. If one does, report it to your state SNAP office.
Disputing a POS Fee That Shouldn’t Be There
Federal Regulation E gives you the right to dispute any incorrect electronic fund transfer on your debit card, including a wrong POS fee. You have 60 days from the date your bank sends the statement showing the error to notify the bank.8Consumer Financial Protection Bureau. 1005.11 Procedures for Resolving Errors Miss that window and the bank has no obligation to investigate.
Once you report the error, the bank has 10 business days to investigate and resolve it. It can extend the investigation to 45 days, but only if it provisionally credits your account within the first 10 business days. The bank may withhold up to $50 of that provisional credit if it reasonably believes the transaction was unauthorized. After the investigation closes, the bank has to report results to you within three business days and correct any confirmed error within one business day.8Consumer Financial Protection Bureau. 1005.11 Procedures for Resolving Errors
For an improper credit card surcharge, the path is different. Contact your card issuer to start a chargeback, and separately report the merchant to the card network. Visa and Mastercard both run online complaint forms for surcharge violations.
How to Pay Fewer of These Fees
- If your bank charges per-transaction PIN debit fees, choose “credit” at the terminal on debit card purchases so the transaction routes through the signature network instead.1Federal Reserve Bank of Chicago. Chicago Fed Letter, No. 221, December 2005 – Debit Card Competition: Signature versus PIN
- Carry a card that waives foreign transaction fees if you travel or buy from overseas sellers with any regularity. The 1% to 3% adds up fast.
- Pay with cash, debit, or a prepaid card at merchants that impose credit card surcharges. Surcharges can’t legally attach to those payment types.
- Before paying a convenience fee online, check whether mail, in person, or ACH bank transfer is accepted at no cost.
- Ask your bank whether a different account tier, or meeting a minimum balance, eliminates per-transaction fees on your current account.
