Introduction
Credit card processing is the backbone of modern digital payments. Whether you’re running an eCommerce store or a physical retail business, understanding how it works is essential. In this blog, we’ll break down the steps, components, providers, and future trends of credit card processing to help banking professionals and tech-savvy entrepreneurs make informed decisions.
What is Credit Card Processing?
Credit card processing refers to the steps involved in authorizing, clearing, and settling a transaction made with a credit card. It involves the movement of funds from a customer’s card account to the merchant’s bank account through secure systems.
How Credit Card Processing Works
1. Authorization
When a customer swipes, taps, or enters their card online, the transaction details are sent to the acquiring bank, which forwards them to the card network (Visa, Mastercard, etc.) and then to the issuing bank. The issuing bank checks for funds and returns an approval or decline.
2. Authentication
During this stage, fraud detection tools verify the identity of the cardholder, often using AVS (Address Verification System) or 3D Secure.
3. Clearing and Settlement
Once authorized, the transaction moves to clearing—where the transaction is confirmed—and then to settlement—where funds are transferred to the merchant’s account (usually within 1–2 business days).
