On a bank statement, “POS” stands for point of sale, and it marks a purchase you made with a debit card, credit card, or digital wallet at a store, restaurant, gas pump, or online checkout. The label identifies the moment money moved from your account to a merchant in exchange for goods or services. Everything after that code — the merchant name, the amount, the date — is the bank’s record of that single purchase.
What a POS Line Item Shows
Federal rules require your bank to list certain details for each electronic fund transfer during a statement cycle: the amount, the date it was credited or debited, the type of transfer, the terminal location, and the name of the merchant involved.1eCFR. 12 CFR 1005.9 – Receipts at Electronic Terminals; Periodic Statements A POS entry pulls those fields together into one line.
The merchant name is the piece that trips people up most. It often looks nothing like the sign on the storefront. The name may be abbreviated, shortened to a parent company you don’t recognize, or shown with generic designations like “Inc.” or “Ltd.” dropped.2Consumer Financial Protection Bureau. Comment for 1026.8 – Identifying Transactions on Periodic Statements For an online or phone purchase, the location field may read “internet order” or “mail order” instead of a city.
Before you flag a POS entry as suspicious, search the merchant name online. A charge from a name you don’t recognize is often a legitimate purchase from a business whose billing name differs from its brand name.
POS vs. ACH vs. ATM on Your Statement
POS is only one of several codes you’ll see. An ACH entry is a direct transfer such as a payroll deposit or an automatic bill payment. An ATM entry is a cash withdrawal at a machine. POS is specifically a card purchase at a merchant. Knowing which is which makes it faster to scan a statement for anything that doesn’t belong.
Why a POS Charge May Show as “Pending”
When you tap or insert your card, your bank checks whether the account has enough funds or available credit, then sends an approval or decline back to the terminal. On approval, the bank places a temporary hold on the purchase amount so the same money can’t be spent elsewhere. Your available balance drops right away, even though the funds haven’t actually moved.
The actual money transfer happens later, during settlement. Merchants collect their approved transactions into a daily batch and submit them for processing, which typically results in final settlement within one to three business days. If a weekend or federal holiday falls in that window, expect a longer wait. The Federal Reserve’s settlement and wire transfer services do not operate on Saturdays, Sundays, or holidays.3Federal Reserve Banks. Fedwire Funds Service and National Settlement Service Operating Hours A Friday-night purchase may not settle until the following Tuesday or Wednesday. During that gap the charge shows as pending, and the held funds stay unavailable.
Pre-Authorization Holds Larger Than the Purchase
A few types of merchants place a hold on your account that exceeds the price of what you actually bought. Gas stations, hotels, and car rental companies are the common examples. A gas station may place a hold anywhere from $1 to over $100 when you start fueling, even if your fill-up costs far less. Hotels routinely hold an amount above the room rate to cover potential incidentals.
The hold sits against your available balance until the merchant submits the final amount, at which point the hold releases and the real charge posts. Your card issuer decides how long the hold lasts, and it can remain for up to 72 hours, sometimes longer over weekends when settlement systems aren’t running. If your balance is tight, these holds can cause declined transactions or trigger overdraft fees on other purchases that hit the account while the hold is still active.
How a POS Charge Can Trigger an Overdraft Fee
The gap between authorization and settlement is where unexpected fees appear. Your bank may approve a purchase because you had enough money at that moment, but by the time the transaction actually settles a day or two later, other charges may have pushed your balance below zero. When that happens, the bank can charge an overdraft fee on a purchase you reasonably believed was covered.4Consumer Financial Protection Bureau. Consumer Financial Protection Circular 2022-06 – Unanticipated Overdraft Fee Assessment Practices
It gets worse when several transactions settle in an unfavorable order. Say you have $100 and make a $50 debit card purchase, dropping available funds to $50. If a $120 automatic bill payment then settles first, the bank can charge an overdraft fee on the bill payment. When the original $50 purchase settles against a now-negative balance, the bank can charge a second fee, even though your balance was sufficient the moment you swiped.4Consumer Financial Protection Bureau. Consumer Financial Protection Circular 2022-06 – Unanticipated Overdraft Fee Assessment Practices
You Can Opt Out of Overdraft Coverage
Federal law gives you a way to avoid these fees for everyday debit card purchases. Your bank cannot charge an overdraft fee on a one-time debit card (POS) transaction or an ATM withdrawal unless you have specifically opted in to the bank’s overdraft service.5eCFR. 12 CFR 1005.17 – Requirements for Overdraft Services If you haven’t opted in, or if you revoke your consent, the bank simply declines POS transactions that would overdraw the account, with no fee. You can opt out by contacting your bank at any time.
One boundary to note: opting out only covers one-time debit card and ATM transactions. Recurring automatic payments and checks can still trigger overdraft fees regardless of your opt-in choice.
Spotting a POS Charge You Didn’t Make
If your debit card is lost or stolen and someone uses it for POS purchases, federal law caps your loss, but the cap depends on how fast you report the problem. The Electronic Fund Transfer Act sets three tiers.6Office of the Law Revision Counsel. 15 USC 1693 – Congressional Findings and Declaration of Purpose
- Report within 2 business days of learning of the loss or theft, and your maximum loss is $50 or the amount of unauthorized charges before you gave notice, whichever is less.
- Report after 2 business days but within 60 days of your statement, and your maximum loss rises to $500, covering the unauthorized charges that occurred after the two-day window and before notice.
- Wait more than 60 days from your statement, and you face unlimited liability for unauthorized charges that occur after the 60-day period. The bank has to show those later charges wouldn’t have happened if you had reported sooner, but the exposure has no cap.
These deadlines apply to debit card POS transactions.7eCFR. 12 CFR 1005.6 – Liability of Consumer for Unauthorized Transfers The practical takeaway is simple: read your statements, and report anything you don’t recognize within two business days of spotting it.
How to Dispute the Charge
You can start a dispute by contacting your bank either orally or in writing. Your notice must reach the bank within 60 days after the statement containing the error was sent. Include your name and account number, identify the transaction, and explain why you believe it’s wrong, with the date and amount if you have them.8eCFR. 12 CFR 1005.11 – Procedures for Resolving Errors If you call first, the bank can require you to follow up in writing within 10 business days, so ask during that first call whether written confirmation is needed and where to send it.
Once the bank has your dispute, it generally has 10 business days to investigate. If it needs more time, it must provisionally credit your account within those 10 business days so you aren’t left without the money. The bank may withhold up to $50 of that provisional credit if it reasonably believes an unauthorized transfer occurred. For most electronic fund transfers, the extended investigation maxes out at 45 days, but disputes involving POS debit card transactions get up to 90 days.8eCFR. 12 CFR 1005.11 – Procedures for Resolving Errors The provisional credit stays available to you throughout.
Credit Card POS Charges Follow Different Rules
If the POS purchase went through as a credit card charge rather than a debit, your dispute falls under the Fair Credit Billing Act. You send a written billing error notice to your card issuer within 60 days of the statement date. The issuer must acknowledge within 30 days and resolve the dispute within two billing cycles, no more than 90 days. It cannot try to collect the disputed amount or report it as delinquent during the investigation.9Office of the Law Revision Counsel. 15 USC 1666 – Correction of Billing Errors
Credit card charges also come with a stronger cap: your maximum liability for unauthorized credit card charges is $50, regardless of when you report them. That’s flatter and more forgiving than the escalating debit card tiers above.
Surcharges and Cash Back at the Register
Some merchants add a surcharge to your total when you pay with a credit card. Card networks limit how much can be added. Visa caps surcharges at 3% of the transaction or the merchant’s actual processing cost, whichever is lower.10Visa. U.S. Merchant Surcharge Q and A Merchants must post notice at the store entrance, at the checkout terminal, and on your receipt as a separate line item. Surcharges are not allowed on debit card or prepaid card transactions.
Credit card surcharges aren’t legal everywhere. As of 2025, eleven states and Puerto Rico prohibit merchants from adding surcharges to credit card transactions.11National Conference of State Legislatures. Credit or Debit Card Surcharges Statutes If you’re in one of those places, a merchant charging extra for credit card use may be violating state law.
Separately, many retailers offer cash back at the POS terminal when you pay with a debit card. Most major retailers provide the service for free, though some charge a small fee that varies with the amount of cash you request. Any fee should appear as a separate charge or be disclosed before you confirm the transaction.
