In retail, hospitality, and eCommerce, payments move fast understanding how they work is essential for both business owners and customers. A POS transaction is one of the most common payment interactions today. Whether you swipe a debit card at a grocery store, tap your phone at a cafe, or insert a chip card at a retail counter, you’re completing a POS transaction.
This guide explains what is POS transaction, how it works, the different types, fees, risks, and what retailers must know to stay compliant and reduce payment disputes.
What Is POS Transaction?
A POS transaction is a payment made at the “Point of Sale”, the moment when a customer pays for goods or services using a card, mobile wallet, or contactless method.
The POS system records the sale, sends the payment request to the issuer bank, and confirms whether the payment is approved.
In simple terms:
POS = the place (physical or digital) where the payment happens.
POS Transaction = the payment initiated using a card or digital payment method.
Retailers rely on POS transactions to verify funds, reduce fraud, and update inventory in real time.
Why POS Transactions Matter in Retail
For store owners, POS transactions impact:
-
Revenue accuracy
-
Inventory updates
-
Payment reconciliation
-
Fraud prevention
For customers, POS transactions offer:
-
Faster checkout
-
Safer payments than cash
-
Easy refunds and returns
-
Digital records of purchases
How a POS Transaction Works (Step-by-Step)
Every POS transaction, debit, credit, or contactless follows the same process:
1. Customer initiates payment
A card is tapped, inserted, swiped, or scanned.
2. POS terminal sends card details securely
Terminals encrypt the data to prevent theft.
3. Payment processor routes the request
It sends details to the issuing bank (customer’s bank).
4. Bank checks for funds and fraud risk
The bank verifies:
-
Available balance
-
Card validity
-
Purchase risk rating
5. Bank approves or declines
A response returns in 2–5 seconds.
6. POS prints or shows confirmation
Payment is completed, and inventory is updated.
What Is POS Transaction in Debit Card?
When someone asks what is pos transaction in debit card, it refers to a payment made using a debit card at a store checkout or online POS-enabled system. The purchase amount is deducted directly from the customer’s bank account.
Characteristics of a POS debit card transaction:
-
Money is withdrawn instantly
-
Requires PIN or contactless tap
-
Has lower fees for merchants compared to credit cards
-
Often seen as “POS DEBIT” on bank statements.
What Is a POS Debit Transaction?
A POS debit transaction means the customer paid using a debit card rather than credit. It’s logged as a direct debit from their checking account.
Example on a bank statement:
“POS DEBIT – Walmart Supercenter”
Retailers prefer POS debit transactions because settlement fees are often lower.
What Is a POS Debit Card Transaction?
This term is commonly used by banks. It means:
A customer used a debit card at a POS machine to buy something at a store, restaurant, gas station, or online.
Nothing more complex, just a debit card used at a point of sale.
What Is a POS Transaction Type?
There are several POS transaction types, including:
1. Card-Present Transaction
Where the customer physically uses their card (tap, chip, swipe).
Examples: Grocery stores, pharmacies, clothing stores.
2. Card-Not-Present POS Transaction
Online payments on POS-enabled checkout systems.
Examples: eCommerce stores, delivery apps.
3. Contactless POS Transaction
Using NFC tap:
-
Apple Pay
-
Google Pay
-
Contactless debit/credit cards
4. PIN-based POS Transaction
Customer enters a PIN to verify identity.
5. Signature-based POS Transaction
More common with credit cards.
6. EMV Chip POS Transaction
Safer chip-based transactions replacing magstripe.
What Is Domestic POS Transaction?
A domestic POS transaction is a payment made within the same country using a card issued in that country.
Example:
A customer with a Pakistani debit card buying groceries at a supermarket in Karachi.
Banks often charge lower fees for domestic POS transactions than for international transactions.
What Is ATM POS Transaction?
This term confuses many customers. An ATM POS transaction occurs when:
-
A debit card is used at a retail POS terminal
-
AND
-
The terminal uses the ATM network (like Plus, Cirrus, or Link) to process the payment.
It appears on statements as:
“ATM/POS Transaction”
This happens when the issuing bank routes the purchase through ATM rails instead of regular card rails.
What Is POS Transaction Fee?
A POS transaction fee is the charge a bank or merchant pays for processing the payment. Fees vary depending on:
-
Card type (debit vs credit)
-
Merchant category
-
Network (Visa, Mastercard, UnionPay, local networks)
-
Country regulations
Typical fee components include:
-
Interchange fee
-
Processor markup
-
Network fee
These fees ensure secure settlement between banks, processors, and networks.
What Is POS Merchant Transaction?
A POS merchant transaction is any transaction initiated at the merchant’s point of sale. The retailer’s POS machine captures:
-
Payment amount
-
Card details
-
Approval response
-
Timestamp
-
Store ID
Merchants use this data for reconciliation, refunds, and reporting.
What Is POS 90 Transaction?
A POS 90 transaction usually refers to a transaction code used in specific countries (such as India or certain bank networks). “90” identifies:
-
A purchase transaction
-
No cashback involved
-
No withdrawal
-
Direct sale at the point of purchase
Banks use these codes for reporting and compliance.
Examples of POS Transactions
1. Grocery Store Checkout
A shopper taps their debit card for a $45 purchase. The bank approves in 2 seconds. It's logged as a POS debit transaction.
2. Small Retail Boutique
A clothing store processes a chip card payment. Inventory updates instantly, and the receipt shows an EMV POS transaction.
3. Restaurant Bill Payment
A server brings a handheld POS machine. The guest inserts their card and enters a PIN.
4. Gas Station Pay-at-Pump
The customer pays without entering the store. This is also a POS merchant transaction.
5. Mobile Wallet Tap at a Café
A customer taps their phone using Apple Pay. This counts as a contactless POS transaction.

|---|---|---|
| Purpose | Purchase goods & services | Withdraw cash |
| Requires PIN | Sometimes | Always |
