POS stands for Point of Sale. In banking and retail, POS refers to both the physical location where a transaction between a buyer and a merchant is completed and the electronic terminal (POS machine) used to process card-based payments. When you swipe, dip, or tap your debit or credit card at a store, restaurant, or petrol pump to make a payment, you are conducting a POS transaction through a POS terminal.

POS Meaning and Definition
POS in banking means a system — comprising hardware and software — at a merchant location that enables customers to make payments for goods or services using debit cards, credit cards, UPI, mobile wallets, or contactless payment methods, with the transaction processed and settled electronically between the customer’s bank and the merchant’s bank.
From a banking perspective, a POS transaction occurs when a customer uses a payment instrument (card, mobile device) at a merchant’s terminal. The transaction is routed through the acquirer bank (the merchant’s bank) to the card network (Visa, Mastercard, RuPay) and then to the issuer bank (the customer’s bank), which authorises or declines the payment. The merchant’s account is credited on T+1 (the next working day after the transaction date).
In India, POS terminals are issued to merchant establishments by acquirer banks. Banks like SBI, HDFC, Axis, and Union Bank provide POS terminals to merchants free of charge, with the bank bearing the cost of procurement and maintenance. The merchant pays a Merchant Discount Rate (MDR) — a small fee charged by the acquirer bank per transaction — in exchange for the payment acceptance service.
How a POS Transaction Works — Step by Step
Step 1 — Item Selection: The customer selects goods or services and proceeds to the checkout counter where the POS terminal is installed.
Step 2 — Card Presentation: The customer swipes (magnetic stripe), inserts (EMV chip), or taps (NFC contactless) their debit or credit card on the POS machine, or scans a UPI QR code.
Step 3 — PIN Authentication: For chip and PIN transactions, the customer enters their 4 or 6-digit PIN on the POS keypad. Contactless transactions below a certain limit (typically Rs.5,000) do not require a PIN.
Step 4 — Bank Authorisation: The POS terminal sends the transaction details to the acquirer bank, which routes it through the card network to the issuer bank. The issuer bank verifies the available balance and PIN, then returns an approval or decline response within seconds.
Step 5 — Settlement: On T+1, the acquirer bank credits the net transaction amount (after deducting MDR) to the merchant’s current account. The customer’s account is debited and the transaction appears on their bank statement as a POS debit entry.
