How Does Credit Card Processing Work?

Credit card payments have become essential for modern commerce, used in nearly every facet of daily life. Whether shopping online, dining at a restaurant, or paying for services, the ease of using a card and the various credit card perks offered are appealing. But have you ever wondered what happens when a credit card transaction occurs?

Understanding how credit card processing works is vital for business owners and consumers. This guide breaks down the intricate system of transactions, approvals, and transfers that allow payments to happen quickly and securely, providing clarity on each step from authorization to settlement.

What is Credit Card Processing?

Credit card processing is when a cardholder initiates a payment, and the funds transfer to the merchant’s account. It involves multiple entities working together to ensure the transaction is authorized, secure, and completed.

When a customer purchases using a credit card, a complex process begins between the merchant, the payment processor, the card network, and the issuing bank. This system verifies the card details, checks for sufficient funds, and ensures the transaction is legitimate before the funds go to the merchant. Although this process happens in a matter of seconds, it involves several steps designed to protect the consumer and the business.

Key Players in Credit Card Processing

Several key players work behind the scenes to ensure the seamless processing of credit card transactions. Each of these entities plays a vital role in facilitating and securing payments:

1. Cardholder: The customer who purchases using a credit card issued by their bank. They initiate the transaction by presenting their card details to the merchant.

2. Merchant: The business or vendor that accepts credit card payments for goods or services. The merchant must have a system, like a point-of-sale (POS) terminal or an online payment gateway, to process these transactions.

3. Payment Processor: The company responsible for handling the transaction between the merchant and the card networks. The payment processor ensures that the cardholder's information is transmitted securely and verifies the transaction details with the card issuer.

4. Card Networks: Also known as card schemes (e.g., Visa, Mastercard, American Express), these networks facilitate communication between the issuing bank and the acquiring bank. They set the rules and standards for processing transactions and handle the routing of payment data.

5. Issuing Bank: The financial institution that issues the credit card to the cardholder. When a transaction is initiated, the issuing bank is responsible for verifying details, checking for available credit, and approving or declining the transaction.

6. Acquiring Bank: The acquiring bank manages the merchant’s account and processes the credit card payments. Once the transaction is authorized, the acquiring bank collects the funds from the issuing bank and deposits them.

How Credit Card Payments Work

Credit card payments may seem simple, but behind every transaction is a detailed process involving multiple steps and entities from when a customer uses their credit card, seeing purchases as pending transactions, and the merchant receives the funds.

Authorization

The payment process starts when a customer provides a credit card for a product or service in-store or online. The merchant’s system, such as a point-of-sale (POS) terminal or an online payment gateway, captures the card details and sends them to the payment processor.

The payment processor forwards the transaction information to a card network like Visa or MasterCard, which then communicates with the cardholder’s issuing bank. The issuing bank verifies the information, checks for available funds or credit, and evaluates the transaction for potential fraud.

Authentication

In some cases, particularly for online transactions, the issuing bank may require additional authentication to confirm the legitimacy of the purchase. This step could involve two-factor authentication, such as entering a one-time code sent to the cardholder via SMS or email.

Authentication adds a layer of security to help prevent fraudulent activities. It ensures that the person using the card is the authorized cardholder, protecting both the consumer and the merchant.

Capture

The authorized amount is set aside from the cardholder’s credit limit or available funds. While the merchant has received approval for the payment, the funds have not yet reached their account.

For in-person transactions, capture happens immediately. Capture may occur later for online purchases or delayed fulfillment, such as when the merchant ships the product. It ensures the funds are reserved but not officially transferred until the goods or services are delivered.

Clearing and Settlement

Once the payment is captured, the merchant submits all their authorized transactions in a batch to their acquiring bank, usually at the end of the business day. The acquiring bank forwards the payment data to the card networks, which then communicate with the cardholder’s issuing bank.

The issuing bank transfers the funds to the acquiring bank, which deposits the amount into the merchant’s account. This process is called clearing and settlement. The actual funds transfer, known as settlement, typically takes 1 to 3 business days.

Funding

The final step in the credit card payment process is funding. The acquiring bank deposits the funds, minus processing fees, into the merchant’s account. The merchant has the payment, and the credit card transaction is officially completed.

Credit Card Processing Fees and Pricing Structures

Credit card processing fees can significantly impact a business’s bottom line, so understanding how these fees work is crucial for managing costs. Merchants pay several types of fees for the ability to accept credit card payments, and these fees vary depending on the pricing structure agreed upon with their payment processor.

Common Credit Card Processing Fees

• Interchange Fees: Interchange fees are the largest component of credit card processing costs set by the card networks. These fees are paid to the cardholder’s issuing bank and cover the cost of transferring funds from the cardholder to the merchant. Interchange fees vary depending on the type of card used, the transaction type, and the merchant’s industry.

• Assessment Fees: Assessment fees are charged by the card networks for the use of their payment infrastructure. These are usually a small percentage of the transaction value and are the same across all processors. The assessment fee is in addition to the interchange fee.

• Processor Markup: Payment processors charge a markup for handling the transaction. This markup can vary greatly depending on the processor and the type of pricing structure used. It can be a flat fee per transaction or a percentage of the transaction value.

• Monthly Fees: Many payment processors charge a monthly service fee to cover administrative costs. It can include access to customer support, account management, and other services.

• Gateway Fees: A gateway fee may incur for businesses that process payments online. This fee covers the cost of using a payment gateway, which securely transmits payment information between the merchant and the processor for online transactions.

• PCI Compliance Fees: To ensure secure transactions, merchants must comply with the Payment Card Industry Data Security Standard (PCI DSS). Some processors charge a monthly or annual fee to help merchants maintain PCI compliance.

Credit Card Processing Pricing Structures

• Flat-Rate Pricing: With flat-rate pricing, the merchant pays a single rate for all transactions, regardless of the card type or transaction method. Flat-rate pricing is simple and predictable but may not be the most cost-effective option for businesses with high transaction volumes.

• Interchange-Plus Pricing: Interchange-plus pricing is one of the most transparent and cost-effective pricing models. Merchants pay the interchange fee set by the card networks, plus a fixed markup from the processor.

• Tiered Pricing: In tiered pricing, transactions are grouped into different categories, such as qualified, mid-qualified, and non-qualified transactions. Qualified transactions are usually the least expensive (e.g., swiped debit cards), while non-qualified transactions (e.g., keyed-in or international cards) incur higher fees. While tiered pricing may appear straightforward, it can be less transparent, as merchants may not know which transactions fall into which tiers until they see the statement.

• Subscription Pricing: Subscription pricing involves paying a monthly fee for access to the processor’s services, plus a small per-transaction fee (e.g., $0.05 per transaction). This structure is ideal for businesses with high transaction volumes, as it minimizes the percentage-based fees, allowing them to save on processing costs.

Choosing the Right Processing Structure

Selecting the right pricing structure depends on several factors, including transaction volume, average transaction size, and the types of credit cards customers use. Businesses with high volumes and larger transaction amounts may benefit from interchange-plus or subscription pricing. In contrast, smaller businesses or those with lower sales volumes might find flat-rate pricing more predictable and easier to manage.

Choosing a Credit Card Processing System

Selecting the right credit card processing system is a crucial decision for any business, as it directly impacts customer experience, transaction security, and overall operational costs. With various options available, businesses can consider several key factors when choosing a credit card processor that aligns with their needs and goals. Here are some important considerations to help guide the decision-making process:

1. Transaction Types and Business Model: Ensure the processor supports the transactions you handle, such as in-person, online, or mobile. Consider any specific needs like recurring billing, invoicing, or multi-channel payments.

2. Fees and Pricing Structures: Evaluate pricing models such as flat-rate, interchange-plus, tiered, or subscription pricing. Compare transaction fees, monthly fees, and hidden charges like setup, PCI compliance, or cancellation fees.

3. Integration with Existing Systems: The processing system should integrate with your existing POS, accounting, inventory management, or e-commerce platform to ensure seamless operations and reduce manual errors.

4. Security and PCI Compliance: Choose a PCI DSS-compliant processor offering features like encryption, tokenization, and fraud protection tools to safeguard sensitive data and prevent fraud.

5. Customer Support and Reliability: Opt for a processor that provides 24/7 customer support via phone, email, or chat, and has a proven track record of minimal downtime and transaction errors.

6. Scalability and Growth Potential: Choose a processor that can grow with your business, offering support for new payment methods and accommodating higher transaction volumes without compromising performance.

7. Additional Features and Value-Added Services: Some processors offer extra services like analytics, sales reports, loyalty programs, or gift card options. These can add value and enhance customer engagement beyond basic payment processing.

8. Reputation and Reviews: Research reviews and customer feedback to ensure the processor has a strong reputation for reliability, transparency, and excellent customer service. A well-established company is more likely to provide consistent support.

What Happens When the Transaction is Declined?

A declined credit card transaction is frustrating for the merchant and the customer. When a customer attempts to make a purchase, the merchant's payment processor sends the transaction details to the card network, which then checks with the issuing bank. If the transaction is declined because of insufficient funds, suspicious activity, or incorrect card details, the bank informs the card network, which notifies the processor and the merchant.

Upon receiving the decline notification, the merchant should promptly inform the customer about the issue. They can offer to retry the transaction, ask for verification of card details, or suggest alternate payment methods. If customers believe the decline is in error, they should contact their issuing bank for clarification and check their card details for accuracy.

Frequent declines can negatively impact a merchant’s business by harming customer experience and potentially leading to chargebacks. Merchants should track decline rates to identify patterns and improve payment processing strategies.

Credit Card Processing for Foreign Transactions

Processing credit card transactions across borders involves unique considerations for businesses and customers. Understanding these dynamics is essential for creating a seamless payment experience.

For Businesses

When a customer uses a credit card from another country, the transaction is considered a foreign transaction, requiring currency conversion to the merchant's local currency. Businesses should select payment processors that support multi-currency transactions to enhance customer experience and improve conversion rates.

It's essential to be aware of fees associated with foreign transactions, including currency conversion and international transaction fees, as these can impact profit margins. Additionally, implementing fraud detection measures like the Address Verification Service (AVS) and ensuring compliance with payment network regulations are critical for protecting customer data and reducing fraud risk.

For Customers

Customers can benefit from the ability to pay in their currency, which simplifies the purchasing process. Find merchants with clear currency options and various payment methods, such as digital wallets. Understand potential fees, such as foreign transaction fees, imposed by their credit card issuer, to make informed purchasing decisions.

In case of a declined transaction or fraud alert, customers can contact their issuing bank for clarification, ensuring a smoother shopping experience.
