Every time you swipe, tap, or enter your credit card, a lot happens in a few seconds. Processing the transaction involves security checks, banks clearing transactions, and money transfers.  

This guide covers credit card payment processing, how to choose a system and the associated fees. Selecting the right credit card payment system can save your business money. Plus, it can enhance customer satisfaction. 

What Is Credit Card Processing? 

Credit card processing is what allows businesses to accept credit card payments. It’s a step-by-step process that moves money from the customer’s bank account to your business account. 

The process is the same for in-person and online credit card payments. In stores, a point-of-sale (POS) terminal handles the transaction. Online, a payment gateway or checkout portal does the same job. Both systems secure credit card transactions, protecting business and customer information.

Credit Card Merchant Processor Key Components 

Behind every payment, a network of systems works together to keep it smooth and safe. 

The components include: 

• Cardholder (Buyer). The customer uses their credit card to make a payment. The issuing bank, which holds the cardholder’s account, then authorizes the transaction. 
• Merchant (Seller). A business or person selling a product or service that takes credit cards as a payment option. The acquiring banks or payment service providers handle payment processing.  
• Point-of-Sale (POS) System. An in-store terminal or online platform that collects payment details.  
• Payment Gateway. This is the digital bridge between the POS and the payment processor. It encrypts, secures, and sends payment data. The gateway protects sensitive cardholder information during the transaction. 
• Credit Card Processor. The processor handles payment authorization. It routes the merchant’s payment request to the correct card network and replies. The processor checks security and regulatory compliance. 
• Card Networks. Major card networks include Visa, Mastercard, American Express, and Discover. They connect payment processors with issuing banks. These networks manage transaction standards, fees, and rules. 
• The Acquiring Bank. The seller’s bank receives the funds from the buyer’s bank. 

How Does a Credit Card Transaction Work? 

Credit card transactions involve three main steps: authorization, authentication, and settlement. Here’s how they play out: 

1. Authorization: The bank verifies the card and funds available. 
2. Authentication: The system confirms the cardholder’s identity to prevent fraud. 
3. Settlement: The bank transfers funds to the merchant’s account. 

Here’s a more detailed breakdown of the steps involved in credit card payments: 

1. Initiation 

For in-person transactions, the process starts when a customer swipes, taps, or inserts their card into your POS system. For online or mobile payments, customers enter their card details into the payment fields. 

2. Data Transmission 

Your POS system or website sends the payment data to a payment gateway. The gateway encrypts the information and sends it to the processor. 

3. Authorization Request 

The processor sends a request to the card network (like Visa or Mastercard). The card network then passes it on to the customer’s issuing bank. 

4. Approval or Decline 

The issuing bank checks if the customer has enough credit or funds for the transaction. Then, it approves or declines the transaction and responds to the merchant. 

5. Authorization Response 

The POS system or website receives the response and proceeds or declines the transaction. 

6. Settlement 

The processor settles the payment with the issuing bank. They transfer funds into your merchant account. 

7. Funds Transfer 

The funds transfer usually takes the longest of all these steps. You’ll receive the funds in your business account within one to three business days.

Why Credit Card Payment Systems Matter for Small Businesses 

Using credit cards for payments simplifies processes. They speed up transactions, and customers usually expect the ease of digital payment options. 

Here is why it matters: 

Enhanced Customer Experience 

Offering payment options creates seamless shopping experiences. The easier it is to make a purchase, the more positive the impression it makes on a customer. This encourages customer loyalty. 

Increased Sales and Revenue 

Accepting credit card payments can expand your customer reach and boost purchases. It lets customers make purchases they might otherwise not. This increases sales. 

Improved Cash Flow 

Faster payments mean better cash flow. This gives you more opportunities to reinvest in your business. 

Secure and Compliant Transactions 

To accept credit card payments, you need to comply with industry standards like PCI DSS. Meeting these regulations reduces fraud and protects customer data. This also increases customer trust and your reputation.  

Competitive Advantage 

Modern payment systems meet customer expectations. They can provide an advantage over competitors who use traditional methods. 

Cost Optimization 

Choosing the right credit card processor can help businesses save money and improve profits. 

What to Know About Credit Card Payment System Fees 

Credit card processing fees vary depending on the parties involved in the transaction. Understanding these fees is essential. Comparing them can help you choose the best processing solution for your business.  

Below is an overview of fees that may encounter: 

• Interchange Fees. The cardholder’s issuing bank charges sellers interchange fees to process each transaction. The fees usually include a percentage of the transaction amount and a fixed cost. Rates vary depending on transaction type and card brand. 
• Assessment Fees. Card networks charge fees to cover the use of their payment infrastructure. These fees are usually a small percentage of the transaction amount. 
• Processor Markup. Credit card processors charge merchants fees for transaction authorization and settlement. These fees cover the communication costs with card and bank networks. They can be a flat rate, a percentage of the transaction, a set amount, or a monthly fee. 
• Payment Gateway Fees. Payment gateway fees apply to online transactions to ensure secure data transmission. They usually charge monthly or per-transaction fees. 
• Terminal and Equipment Fees. POS terminals and card readers for in-person transactions have costs. Your business can buy or lease the equipment. The terminal suppliers may charge for software updates and maintenance. 
• Setup and Activation Fees. There might be one-off costs to set up and activate the accounts. 
• Monthly and Annual Fees. Maintenance and reporting may have recurring fees. 
• Chargeback Fees. Processors charge a fee to manage the chargeback process. (This is when a customer disputes a charge.)  
• PCI Compliance Fees. This is the fee that a payment processor charges to set up data security compliance.

Here are seven tips to find the ideal credit card payment processing solution: 

1. Prioritize Security and Compliance. Keeping customer data safe is crucial. Choose a system with robust security features like tokenization and encryption.

6. Choose a Provider with Excellent Support. Reliable customer support can boost your business’s success. Knowledgeable and responsive technical support saves time and reduces stress. 
7. Look for Advanced Reporting and Analytics. A great payment processor does more than process payments. It provides insights into transaction trends, customer behavior, and revenue patterns. These analytics can help you make informed decisions and grow your business.

Frequently Asked Questions 

How long does it take for a credit card payment to process? 

Most credit card processors take 1–3 days to complete payments. This timing can vary based on the processor, the cardholder’s bank, and the type of card used. Debit card payments linked to credit networks often clear faster. Some processors offer faster services for quicker deposits into merchants’ accounts. Remember that weekends and holidays can slow down credit card payment processing times. While it seems instant at checkout, several systems verify and approve the transaction. 

What happens if a payment is processing? 

When a payment is “processing,” the system verifies the credit card order. First, the system sends the payment to the cardholder’s bank for approval. The bank checks if the card is valid, ensures enough funds are available, and looks for fraud issues. The bank approves the payment and notifies the merchant’s processor. The processor then makes the funds available for the merchant.  

Who pays for credit card processing? 

Businesses usually pay 1.5–3% in fees for credit card transactions. Fees vary by card type and agreement. Some businesses absorb the cost while others raise prices to pass it to customers.
