Processing credit cards can be a complex process, but understanding the basics can make all the difference.
You need to have a merchant account, which is a special kind of bank account that allows you to accept credit card payments.
The merchant account is linked to a payment gateway, which is the technology that actually processes the transaction.
To get started, you'll need to choose a payment processor, such as PayPal or Square, that will help you set up your merchant account and payment gateway.
Once you're set up, you'll need to obtain a credit card machine or mobile reader to process transactions.

What is Credit Card Processing?
Credit card processing is the process of authorizing, authenticating, and settling electronic transactions involving credit cards between the cardholder, the business, and their respective financial institutions.
This process allows businesses to accept credit card payments for goods or services, making it easy and convenient for both the business and the customer.
Credit card processing involves a series of steps, including selecting a merchant account, which is a specific type of bank account that allows businesses to accept payments by debit, credit, or gift card.
A merchant account is an agreement between a retailer, a merchant acquiring bank, and a payment provider for the processing of credit and debit card transactions.
To process credit cards, businesses need to select a POS system, which is the combination of hardware and software that allows brick-and-mortar merchants to capture in-person credit card payments.
A POS system can also help merchants manage their business operations, from tracking inventory to scheduling appointments to logging employee hours.
Online credit card processing solutions are different from what brick-and-mortar retailers need, and vice versa.
Here are the minimum steps to get started with payment processing:
- Select a merchant account
- Select a POS system
- Select a payment gateway
A payment gateway is necessary for online credit card processing and is linked to your business's online checkout form or shopping cart.
How Credit Card Processing Works
Credit card processing is a complex process, but it can be broken down into a few simple steps. The entire process usually takes 1-3 business days.
The first step is authorization, where the cardholder's card information is sent to the merchant bank or payment processor, which then routes the information through the card network to the issuing bank. The issuing bank checks the card details and verifies the cardholder's account status and available credit.
The card network deducts the purchase amount from the card-issuing bank before sending the transaction balance to the payment processor or acquiring bank (minus fees). The card-issuing bank deducts the amount from the customer's account before sending an invoice or statement to the cardholder (minus fees).
Here's a simplified overview of the credit card transaction process:
- Initiation: The cardholder provides their credit card information to the business.
- Data transmission: The business's POS system or payment gateway captures the transaction details and securely transmits this information to the credit card processor.
- Authorization request: The credit card processor forwards the transaction data to the appropriate card network, which then routes the authorization request to the issuing bank.
- Approval or decline: The issuing bank verifies the cardholder's account, checking for sufficient funds and any potential fraud or security issues.
- Authorization response: The credit card processor sends the authorization response—either an approval or a decline code—to the business's POS system or payment gateway.
- Settlement: The business submits the batch of all approved transactions to the credit card processor for settlement.
- Funds transfer: The card networks coordinate with the issuing banks to transfer the funds for each transaction to the acquiring bank.
- Cardholder billing: The issuing bank adds the transaction amount to the cardholder's account balance and includes it in the monthly statement.
How It Works: Quick Guide
Credit card processing is a complex system, but it can be broken down into a few simple steps. Here's a quick guide to get you started:
Credit card processing begins with the cardholder presenting their card to the merchant, whether it's online or in-person. This can be done by swiping, inserting, or tapping the card, or by entering the card details manually.
The merchant's POS system or payment gateway captures the transaction details and securely transmits this information to the credit card processor. This process usually takes only a matter of seconds.
The credit card processor forwards the transaction data to the appropriate card network, which then routes the authorization request to the issuing bank. The issuing bank verifies the cardholder's account, checking for sufficient funds and any potential fraud or security issues.
The card network debits the issuing bank for each transaction amount and credits the merchant bank. The merchant bank then deposits the transaction amount into the merchant's account, minus any processing fees.
Here's a simplified overview of the credit card processing timeline:
The entire process usually takes 1-3 business days, depending on the card network and the merchant's processing speed.
Authorization
Authorization is the critical step where the credit card issuer verifies the cardholder's account and checks for sufficient funds and potential fraud or security issues. The issuer either approves or declines the transaction and communicates this decision to the card network, which relays the information to the credit card processor.
The cardholder starts the authorization process by providing their card information through the merchant's card-reading device, which sends the information to the merchant bank or payment processor. The payment processor then routes the information through the appropriate card network to the issuing bank.
The issuing bank confirms the card details and checks the cardholder's account status and available credit before sending an approval or denial to the merchant bank. The merchant bank or payment processor then forwards the decision to the merchant's card reader.
For online and e-commerce card transactions, the authorization process may be slightly different and could require a payment gateway in addition to a payment processor. The payment gateway routes the payment information to the processor, which securely transmits the payment information via the payment processor to the issuing bank for authorization.
The payment processor, appointed by a merchant, handles credit and debit card transactions for the merchant/acquiring bank. The payment processor routes the transaction information to the card network, which sends an authorization request to the issuing bank.

Key Components and Requirements
To process credit cards, you need several key components and requirements. The cardholder, merchant, and acquiring bank are all crucial parties in the process.
The cardholder is the individual who owns the credit card and uses it to make purchases. The merchant is the business or service provider that accepts credit card payments from customers. The acquiring bank is the financial institution that has a contractual relationship with the business to accept and process credit card transactions.
The point-of-sale (POS) system is the hardware and software the business uses to accept and process credit card transactions. This includes terminals, card readers, and software applications. The payment gateway is a service that securely transmits transaction information between the business's POS system and the credit card processor.
A payment processor, or merchant services company, helps manage the transaction process with the merchants, banks, and card networks. They ensure the transfer of funds and often offer the hardware and software required to accept card transactions. Credit card networks, such as Visa, Mastercard, American Express, and Discover, are responsible for the infrastructure that allows the transmission of credit card details between the merchant bank and the issuing bank.

To process credit cards, a merchant will typically need hardware and software to capture the information needed to process a credit card transaction. This can be as simple as a compact card reader that plugs into a smartphone or a device with more features, such as a terminal, register, or an entire point-of-sale system.
Here are the key components involved in processing credit card transactions:
- Cardholder: The individual who owns the credit card and uses it to make purchases.
- Merchant: The business or service provider that accepts credit card payments from customers.
- Acquiring bank: The financial institution that has a contractual relationship with the business to accept and process credit card transactions.

- Payment processor: A merchant services company that helps manage the transaction process with the merchants, banks, and card networks.
- Card networks: The infrastructure that allows the transmission of credit card details between the merchant bank and the issuing bank.
Businesses and Fees
Credit card transaction processing costs can vary depending on the type of credit card, transaction volume, and individual payment processor.
Interchange fees are typically a percentage of the transaction amount, plus a fixed fee per transaction, and can depend on the type of card, business industry, and how the card is used in the transaction.
Assessment fees are usually a small percentage of the transaction amount and can vary depending on the card network and transaction volume.
Businesses need to understand these costs to make informed decisions and minimize payment processing expenses.
Here are the main types of credit card transaction processing costs:
- Interchange fees
- Assessment fees
- Processor markup
- Payment gateway fees
- Terminal and equipment fees
- Setup and activation fees
- Monthly and annual fees
- Chargeback and retrieval fees

Businesses
As a business owner, you're likely no stranger to the world of credit card fees. From interchange fees to processor markups, it can be overwhelming to keep track of all the different costs involved in credit card transaction processing.
Interchange fees, for example, are typically a percentage of the transaction amount, plus a fixed fee per transaction. This can vary depending on the type of card, the business's industry, and how the card is used in the transaction.
Assessment fees, on the other hand, are charged by card networks for the use of their payment infrastructure. These fees are usually a small percentage of the transaction amount and can vary depending on the card network and the transaction volume.
Businesses may also need to consider payment gateway fees, which can be a monthly fee or a per-transaction fee for online transactions. Additionally, terminal and equipment fees can cover the cost of purchasing or leasing POS terminals, card readers, and other equipment.
A different take: Electronic Transaction for Payment Explanation
Here are some common credit card transaction processing costs that businesses should be aware of:
- Interchange fees: typically a percentage of the transaction amount, plus a fixed fee per transaction
- Assessment fees: a small percentage of the transaction amount, varying by card network and transaction volume
- Payment gateway fees: a monthly fee or a per-transaction fee for online transactions
- Terminal and equipment fees: covering the cost of purchasing or leasing POS terminals, card readers, and other equipment
- Setup and activation fees: a one-time fee for setting up the merchant account and activating the processing service
- Monthly and annual fees: account maintenance, reporting, and access to additional features or services
- Chargeback and retrieval fees: charged for the chargeback process and retrieval of transaction documentation
- PCI compliance fees: ensuring the security of cardholder data and compliance with the Payment Card Industry Data Security Standard (PCI DSS)
By understanding these costs, businesses can make informed decisions and minimize their payment processing expenses.
Fees Cost
Fees can add up quickly, and understanding what you're paying for is key to managing your business expenses. Credit card processing fees are a significant cost for many businesses.
Interchange fees, set by the card networks, are typically the largest portion of processing fees, ranging from 1.5% to 3.5% of the transaction amount. This fee goes to the issuing bank.
Payment processor fees, on the other hand, go to the payment processor, which may be the merchant bank or a third-party processor. Merchants can also pay additional fees based on the payment processor they use and the services provided.
For example, some payment processors charge a fee for PCI compliance, while others don't. This can add up quickly, so it's essential to understand what you're paying for and how to manage these costs.
Here's a breakdown of the typical credit card processing fees:
Choosing a Company for Your Business

Carefully compare processing costs for different providers to find the most cost-effective solution for your business. This will help you minimize your credit card transaction processing costs.
Interchange fees, assessment fees, processor markup, payment gateway fees, and terminal and equipment fees are all types of costs you'll need to consider when choosing a credit card processing company. Each of these fees can vary depending on the type of card, transaction volume, and provider.
To minimize your costs, negotiate rates and fees with potential providers. This can help you get a better deal and reduce your expenses.
Here are some key factors to consider when choosing a credit card processing company:
- Interchange fees: Look for providers that offer low interchange fees, which can range from 1-3% of the transaction amount, plus a fixed fee per transaction.
- Assessment fees: Check if the provider charges assessment fees, which are usually a small percentage of the transaction amount.
- Processor markup: Compare the processor markup fees of different providers, which can be a percentage of the transaction amount, a per-transaction fee, or a monthly fee.
- Payment gateway fees: Consider the payment gateway fees, which can be a monthly fee or a per-transaction fee.
- Terminal and equipment fees: Factor in the costs of purchasing or leasing POS terminals, card readers, or other equipment.
- Setup and activation fees: Check if the provider charges a one-time fee for setting up the merchant account and activating the processing service.
- Monthly and annual fees: Look for providers that offer competitive monthly and annual fees for account maintenance, reporting, and access to additional features or services.
By carefully evaluating these factors and negotiating rates and fees, you can choose a credit card processing company that meets your business needs and minimizes your costs.
Payment Processing Steps
Payment processing involves several key steps, but it all starts with authorization. When a customer makes a payment, the merchant's point of sale terminal or payment gateway tokenizes and encrypts the payment information before sending it to the payment processor.
The payment processor then routes the data to the customer's card-issuing bank through the card association's network. The card-issuing bank verifies the customer's identity and checks if they have sufficient funds to cover the sale.
If the transaction is approved, the merchant has technically made a sale, but the money isn't deposited into their account yet. This is because the transaction needs to go through the settlement process.
Here are the key steps involved in payment settlement:
- The payment processor deposits the transaction amount in the merchant's acquiring bank (minus any fees).
- The card network deducts the purchase amount from the card-issuing bank before sending this transaction balance to the payment processor or acquiring bank (minus fees).
- The card-issuing bank deducts the amount from the customer's account before sending an invoice or statement to the cardholder (minus fees).
The settlement period typically takes one to two business days, with most transactions being batched together on a daily basis to reduce processing costs.
Step 1: Payment Auth
Payment Auth is the first step in the payment processing journey, and it's where the magic happens. The merchant's point-of-sale terminal or payment gateway tokenizes and encrypts the payment information, like a credit or debit card number, before sending it to the payment processor.
This encrypted data is then routed to the customer's card-issuing bank through the card association's network. Think of it like a secure mailroom, where sensitive information is protected and delivered to the right destination.

The card-issuing bank verifies the customer's identity and checks if they have enough funds to cover the sale. This is like a quick background check to ensure the transaction is legitimate.
Here's a breakdown of the key players involved in payment authorization:
- The merchant's POS terminal or payment gateway
- The payment processor
- The card association's network
- The customer's card-issuing bank
If the transaction is approved, the merchant has technically made a sale, but the money isn't deposited into their account just yet. That's because the transaction needs to go through another step – settlement.
Step 2: Payment Settlement Process
The payment settlement process is a crucial step in the payment processing journey. It's what happens after a transaction has been authorized, and the merchant needs to receive the funds.
The merchant's POS terminal or payment gateway sends the approval to the payment processor, which then deposits the transaction amount in the merchant's acquiring bank minus any fees. This settlement period typically takes one or two business days.
Most transactions are batched together on a daily basis instead of going through the settlement process in real-time. Batching helps to reduce total processing costs, especially among merchants that generate hundreds or thousands of sales every day.
The card network deducts the purchase amount from the card-issuing bank before sending this transaction balance to the payment processor or acquiring bank minus fees. This ensures that the merchant receives the correct amount.
Here's a breakdown of the payment settlement process:
It usually takes one to three business days for the settlement process to be completed. During this time, the merchant can expect to receive the funds in their account.
