Credit Card Processing
The complete system for accepting, authorizing, and settling credit card payments.
What is Credit Card Processing?
Credit card processing encompasses all the steps required to accept card payments: capturing the card data, sending an authorization request through the card network to the issuing bank, receiving approval or decline, and settling the funds to the merchant's account. This involves multiple parties—the merchant, payment gateway, processor, card network (Visa/Mastercard), acquiring bank, and issuing bank—all coordinating in seconds to complete a transaction. Processing can occur in-person (card-present) or online/phone (card-not-present).
Why It Matters
Understanding how processing works helps you optimize costs and avoid problems. Each step adds fees and potential friction. Faster authorizations improve customer experience. Proper data capture qualifies you for lower interchange rates. Settlement timing affects your cash flow. Knowledge of the processing chain helps you troubleshoot issues and negotiate better terms.

Frequently Asked Questions
Authorization happens in 1-3 seconds. Settlement (funds reaching your account) typically takes 1-2 business days, though some processors offer same-day or next-day funding.
Declines can result from insufficient funds, fraud flags, expired cards, incorrect CVV, velocity limits, or issuer-specific rules. About 10-15% of legitimate transactions are incorrectly declined.
Authorization confirms the card is valid and has available credit. Settlement is when funds actually move from the issuing bank to the merchant account.
