What Is Credit Card Transaction Processing?

Credit card transaction processing is the behind-the-scenes system that makes it possible for businesses to accept card payments.
It involves authorizing, authenticating, and settling transactions between the cardholder, your business, and the involved banks.

Done right, it makes payments fast, easy, and secure for both you and your customers.

Key Players in Credit Card Transaction Processing

Even though it only takes a few seconds to pay with a card, there’s a lot going on behind the scenes.
Here’s who’s involved:

• Cardholder: Your customer who’s using their credit card.

• Merchant (You): Your business accepting the card payment.

• POS System: The hardware and software (like card readers and terminals) you use to accept payments.

• Payment Gateway: The secure bridge that sends payment info from your POS to your payment processor.

• Payment Processor: The company (like Stripe, Square, or a wholesale provider) that moves the payment through the system.

• Card Networks: Visa, Mastercard, American Express, Discover — the networks that set the rules and connect banks.

• Issuing Bank: The customer’s bank that gave them the credit card.

• Acquiring Bank: Your business’s bank that receives the money from the transaction.

How Does Credit Card Processing Work?

Whether it’s an in-person tap or an online checkout, the basic flow is the same:

1. Customer Initiates Payment:
   The cardholder provides their credit card details — either by swiping, tapping, inserting their card, or entering it online.

2. Data Gets Sent Securely:
   Your POS system or payment gateway captures and encrypts the payment info, sending it to the payment processor.

3. Authorization Request:
   The processor sends the info to the card network, which routes it to the issuing bank to check if the customer can pay.

4. Approval or Decline:
   The issuing bank verifies the account, checks for fraud, and either approves or declines the transaction.

5. Authorization Response:
   The response comes back through the network and processor to your POS — and you complete the sale if it’s approved.

6. Settlement:
   At the end of the day, your business submits all approved transactions for settlement.

7. Funds Transfer:
   The issuing bank sends the money (minus fees) through the network to your acquiring bank, which deposits it into your account — usually within 1–3 business days.

8. Customer Billing:
   The charge shows up on your customer’s monthly credit card bill.

What Are Credit Card Processing Costs?

Credit card processing isn’t free — but understanding the fees helps you avoid overpaying. Here's what to expect:

• Interchange Fees:
  Charged by the issuing bank — a percentage of the sale + a small flat fee.

• Assessment Fees:
  Charged by the card networks (Visa, Mastercard, etc.) — typically a tiny percentage.

• Processor Markup:
  The processor’s fee for handling the transaction. (This is where businesses often overpay.)

• Payment Gateway Fees:
  Fees for online payment gateways.

• Equipment Costs:
  For card readers, terminals, etc.

• Setup/Activation Fees:
  Sometimes processors charge a one-time setup fee.

• Monthly/Annual Fees:
  For account maintenance, statements, etc.

• Chargeback and Retrieval Fees:
  Fees if a customer disputes a charge.

• PCI Compliance Fees:
  Costs to meet security standards for protecting cardholder data.
