The Basics of Credit Card Processing


At its core, credit card processing involves a series of steps that enable merchants to securely accept payments from customers using credit and debit cards. Here’s a simplified overview of the process:

  1. Initiating the Transaction: When a customer makes a purchase, whether in-store or online, the transaction process begins. The customer provides their card details, including the card number, expiration date, and security code (CVV/CVC).
  2. Authorization: The merchant’s payment terminal or online payment gateway sends the transaction details to the acquiring bank for authorization. This information includes the card details, transaction amount, and merchant identification.
  3. Authentication: The acquiring bank forwards the transaction request to the appropriate card network (e.g., Visa, Mastercard) for authentication. The card network then routes the request to the cardholder’s issuing bank.
  4. Verification: The issuing bank verifies the transaction details and assesses whether the cardholder has sufficient funds or credit available to complete the purchase.
  5. Authorization Response: Based on the verification process, the issuing bank sends an authorization response back to the merchant through the card network and acquiring bank. This response indicates whether the transaction is approved or declined.
  6. Transaction Settlement: If the transaction is approved, the funds are transferred from the cardholder’s account to the merchant’s account. This settlement process typically occurs within a few business days.

Key Players in Credit Card Processing

  • Merchant: The business or entity selling goods or services and accepting card payments.
  • Acquiring Bank: Also known as the merchant bank, this financial institution processes credit card transactions on behalf of the merchant.
  • Issuing Bank: The bank or financial institution that issued the credit card to the cardholder.
  • Card Networks: Companies like Visa, Mastercard, American Express, and Discover that facilitate transactions between issuing and acquiring banks.
  • Payment Gateway: A service provider that securely transmits transaction data between the merchant’s website and the acquiring bank.
  • Payment Processor: A third-party entity that handles the technical aspects of transaction processing, often working with both merchants and acquiring banks.
