How Does Credit Card Processing Work?

Understanding how credit card processing works is essential for any business accepting card payments. Whether managing a brick-and-mortar store or running an online business, credit card transactions are central to modern commerce. They provide customers with the convenience of fast, secure payments while giving businesses access to a broader audience and increased sales opportunities.

However, behind the simplicity of a card swipe or tap lies a complex ecosystem involving multiple entities, including banks, card networks, and payment processors, all working in unison to ensure each transaction is seamless and secure. For businesses, especially those navigating the challenges of high-risk industries, understanding these processes isn't just beneficial—it's critical. Optimizing payment systems can reduce costs, mitigate risks, and enhance customer trust, ultimately driving business growth in an increasingly cashless world.

The Credit Card Payment Process: Step-by-Step

When a customer makes a purchase with a credit or debit card, the transaction involves multiple parties and complex workflows. Here’s how credit card processing works, step by step:

1. Payment Authorization Request

• Initiation: The process begins when the customer swipes, taps, or enters their card details via a payment gateway or terminal.
• Data Transmission: The payment gateway securely transmits transaction data to the merchant's payment processor.
• Card Network Check: The processor sends the request through a credit card network (e.g., Visa, Mastercard, Discover, or American Express) to the card-issuing bank.

2. Authentication by the Issuing Bank

• Validation: The issuing bank confirms if the cardholder’s account has sufficient funds or available credit.
• Fraud Detection: It uses advanced fraud detection tools to ensure the transaction is legitimate.
• Approval or Decline: If everything checks out, the issuing bank approves the transaction and communicates back to the processor.

3. Authorization Notification

• The merchant receives a notification of approval or decline, enabling the transaction to proceed or be halted.

4. Settlement and Funding

• Batch Submission: At the end of the business day, the merchant submits all authorized transactions for settlement.
• Interchange and Acquiring Bank: The acquiring bank, often called the merchant’s bank, processes the payment, deducting interchange fees, processing fees, and other costs before depositing the funds into the merchant's account.

Who Are the Key Players in Credit Card Processing?

Understanding the major entities involved helps clarify how credit card processing works:

• Cardholder: The customer using a credit or debit card to make a purchase.
• Merchant: The business accepting the card payment.
• Payment Gateway: A secure interface that encrypts and transmits transaction data.
• Payment Processor: A company that handles communication between the merchant, card networks, and banks.
• Issuing Bank: The financial institution that issued the customer’s credit or debit card.
• Acquiring Bank: The merchant’s bank that facilitates payment acceptance and fund deposits.
• Card Networks: Visa, Mastercard, Discover, and American Express oversee the communication protocols and set interchange fees.

What Are Credit Card Processing Fees?

Credit card processing fees consist of various charges that cover the roles of multiple players in the payment ecosystem. These include card networks, issuing banks, acquiring banks, and payment processors, each taking a share of the transaction. Factors like the type of card used, the method of the transaction (online, in-person, or card-not-present), and the merchant's industry can all influence the total fees charged.

Here’s a closer look at the main components of credit card processing fees and how they affect your business:

1. Interchange FeesInterchange fees are charged by the issuing bank to the acquiring bank for processing a transaction. These fees cover the risk, handling, and services provided by the issuing bank. The rates can vary depending on factors such as the type of card used (credit vs. debit), the transaction method (in-person vs. online), and the merchant's industry.
2. Assessment FeesAssessment fees are set by the card networks (Visa, Mastercard, Discover, etc.) and are charged for using their payment systems. These fees ensure the card networks can maintain the infrastructure to process millions of transactions daily.
3. Processor FeesThe merchant’s payment processor charges processor fees for managing the transaction flow. This includes tasks like routing payment requests to the appropriate networks and ensuring secure and accurate processing.
4. Other FeesBusinesses may encounter additional charges, such as monthly account fees for maintaining a merchant account or using a payment gateway. Chargeback fees are applied when a customer disputes a transaction, and PCI compliance fees cover the costs of adhering to data security standards to protect sensitive cardholder information.

Reducing these fees requires a strategic approach, including selecting the best credit card processor and leveraging tools like interchange optimization. PayKings specializes in helping businesses minimize these costs while ensuring reliable and secure payment processing tailored to their needs.
