Step-by-Step Guide: How A Credit Card Terminal Processes Payments

Simply put, here's how a credit card terminal operates:

Initiate Transaction: The customer inserts or waves their card—swiped, dipped, or tapped—on the terminal to pay.
Data Reading: The terminal reads the card information through magnetic stripe, EMV chip, or NFC contactless technology.
Data Encryption: The card information is encrypted in real time to secure it.
Authorization Request: The encrypted information is sent by the terminal through a payment gateway to the bank or processor of the credit card (such as Thrifty Payments or other credit card terminal companies).
Bank Verification: The bank checks for card information, verifies whether funds are available, and accepts or rejects the transaction.
Message Sent Back: The approval or rejection message is sent back over the same lines to the terminal.
Receipt and Confirmation: The client receives a receipt, and the merchant's system is updated to reflect the approved payment.

All this takes place in seconds, owing to advanced credit card processing equipment and credit card processing terminals optimized for speed and security.
