At Loyent, we believe having knowledge of how the credit card transaction process works is extremely important for small business owners since payment processing represents one of the biggest costs that merchants must confront. Below, we provide the process that takes place with every swipe.
The Credit Card Transaction Process
Step 1: The customer pays with a credit card
The customer purchases goods/services from a merchant. The transaction is ran through the credit card terminal.
Step 2: Authentication Stage
The merchant’s payment terminal captures the customer’s account information and securely sends it to the acquiring bank. The acquiring bank is the financial institution the merchant obtained their merchant account through.
Step 3: The transaction is submitted
The merchant’s acquirer asks the credit card network (Visa, Mastercard, etc.) to get an authorization from the customer’s issuing bank. The issuing bank is the financial institution the customer obtained their credit card through.
Step 4: Authorization is requested
The credit card network submits the transaction to the issuer for authorization.
Step 5: Authorization response
The issuing bank authorizes the transaction and routes an approval code back to the merchant.
Step 6: Merchant payment
The issuing bank routes the payment to the merchant’s acquirer who deposits the payment into the merchant’s account.
This entire cycle takes place within two to three seconds. That’s pretty impressive if you ask us.
