Have you ever looked at your bank statement and wondered, “Why does one charge say POS and another say ATM? Aren’t they both just payments?” You’re not alone.
A lot of people (and honestly, even some new small-business owners) get confused about the difference. The truth is, POS and ATM transactions might look similar on paper, but they work in completely different ways, and they affect your money, fees, and bank account behavior differently.
So instead of giving you a textbook definition, let’s break it down like you would explain it to a friend over coffee.
What Exactly is a POS Transaction?
A POS transaction happens when you pay someone for something. POS basically means Point of Sale, and it also connects to a POS withdrawal network, which lets customers take cash directly through supported terminals.
Think of it as “I’m buying something, and my card is handling the payment.” That’s it.
Whenever you swipe, tap, or insert your debit/credit card at a store, restaurant, gas station, food truck, salon, or online checkout, you’re doing a POS transaction.
Common examples:
- Buying groceries
- Paying at a restaurant
- Tapping your card at the gas pump
- Using Apple Pay at a clothing store
- Paying online (yes, that counts too, depending on the bank)
A POS transaction pulls money straight from your bank account or your credit line and sends it to the merchant.
Why POS Transactions Feel So Seamless
Because the merchant’s payment terminal (the POS machine) talks directly to your bank in real time.
It checks:
- Is your card valid?
- Do you have enough money?
- Has your card been reported stolen?
If everything checks out, the payment goes through in seconds.
Fees? Usually None for Customers
Most banks don’t charge you a fee for POS purchases. The business pays the processing fees, not you.
What is an ATM Transaction?
An ATM transaction is all about accessing your own cash.
POS = pay a business
ATM = take out your own money
And while a POS terminal is owned by a merchant, an ATM is basically a cash machine run by banks or private operators.
ATM transactions include:
- Withdrawing cash
- Checking your balance
- Transferring money
- Depositing cash (at some machines)
Why ATM Transactions Sometimes Have Fees
When you use an ATM that doesn’t belong to your bank, you usually get hit with:
- A fee from the ATM owner
- A fee from your own bank
- Sometimes a “convenience charge”
In short, ATMs involve more hands in your pocket.
ATMs Don’t Pay Anyone but YOU
This is one huge difference:
- A POS sends money to a merchant.
- An ATM hands money to you, and the machine operator charges you for that convenience.
POS v. ATM: The Big Picture Difference
Let’s put it plainly:
A POS transaction is you buying something.
An ATM transaction is you withdrawing your own cash.
They use different networks, different hardware, and even different fee structures.
POS Transactions Move Money Electronically
No cash involved. You pay the merchant, and it’s done.
ATM Transactions Move Physical Cash
You get actual bills in your hand. The machine simply talks to your bank to check your balance first.
How Banks See these 2 Transactions
Banks categorize them differently on statements because the systems behind them aren’t the same.
POS = Retail Purchase Network
This runs on systems like Visa, Mastercard, Discover, etc. It’s designed for sales.
ATM = Banking Network
These run on systems like:
- Cirrus
- Plus
- Star
- NYCE
These networks handle your money, not business payments.
Why Small Business Owners Should Care
Here’s something many business owners never think about:
A POS transaction helps a merchant earn money.
An ATM transaction does not.
Merchants care about:
- Processing fees
- Speed
- Chargebacks
- Tips (restaurants)
- Integration with inventory
- Daily settlements
ATMs care about:
- Surcharge fees
- Cash loading
- Fraud prevention
- Network uptime
Completely different worlds.
POS Transactions Build a Business’s Reputation
Fast, smooth checkouts = happy customers.
Slow, glitchy checkouts = angry reviews.
ATM Transactions Only Affect Your Banking Activity
Unless you own the ATM, it doesn’t affect your business at all.
Why Regular Consumers Should Care Too
Because confusing POS and ATM fees can cost you money.
POS Should Never Charge You Extra (Usually)
If you see a random POS fee from your bank, call them. It might be a:
- Pre-authorization
- Duplicate charge
- Fraud attempt
Banks remove these when reported quickly.
ATM Fees Add Up Faster than You Think
Using out-of-network ATMs every week? That’s $3 to $10 per transaction. Over a year, that’s hundreds of dollars gone for no reason.
Real-world Examples (Simple and Relatable)
Example 1: POS Transaction
You buy a sandwich for $8. You tap your card. The money leaves your account and goes to the sandwich shop. No ATM fee, no withdrawal fee.
Example 2: ATM Transaction
You withdraw $60 from a random gas station ATM.
- ATM charges $3
- Your bank charges $3
You just paid $6 to access your own $60.
Example 3: When People Mistake One for the Other
Sometimes banks list POS purchases weirdly. It may show:
“POS withdrawal” or “POS debit”
People think they used an ATM. But no, that’s simply how some banks label card purchases.

Final Thoughts
- POS = money from you → business
- ATM = money from bank → you
They’re completely different systems, even if both show up on the same bank statement.
Once you understand the basics, those confusing labels on your statement suddenly make a lot more sense. And if you’re a small business owner, understanding POS systems helps you avoid unnecessary fees and give customers a smoother checkout experience.

FAQs
1. What is the main difference between a POS and an ATM transaction?
A POS transaction happens when you pay a business for a product or service, while an ATM transaction is simply you withdrawing or managing your own cash through a banking machine.
2. Do POS transactions charge extra fees like ATMs do?
Most banks do not charge customers extra for POS purchases. ATM transactions, especially out-of-network ones, can include multiple fees from both the machine owner and your own bank.
3. Why do ATM withdrawals cost more than POS purchases?
ATM withdrawals involve third-party networks and machine operators, which means extra charges. POS transactions only move money electronically to the merchant, so the customer typically avoids additional banking fees.
4. Can online purchases be considered POS transactions?
Yes. Many banks record online card payments as POS transactions because they process through the same payment networks used by physical card terminals, even though the purchase happens digitally.
5. Why do some bank statements show “POS withdrawal” instead of purchase?
Different banks label transactions differently. “POS withdrawal” often just means a card purchase processed electronically, not an ATM cash withdrawal, which can confuse customers reading their statements.
