What is Card Processing?
Card processing refers to the series of steps involved in authorizing, clearing, and settling credit and debit card transactions. It involves multiple parties, including the cardholder, the merchant, the acquiring bank, the issuing bank, and the card network. The process begins when a cardholder presents their card for payment and ends when the merchant receives the funds in their account.
Key Players in Card Processing
- Cardholder: The individual who owns and uses the credit or debit card.
- Merchant: The business that accepts card payments for goods or services.
- Acquiring Bank (Merchant Bank): The financial institution that provides the merchant with the ability to accept card payments. They handle the processing of transactions on behalf of the merchant.
- Issuing Bank: The financial institution that issues the credit or debit card to the cardholder.
- Card Network (e.g., Visa, Mastercard, American Express, Discover): These networks act as intermediaries between the acquiring and issuing banks, facilitating the transaction and setting the rules and standards for card payments.
- Payment Gateway: A technology that connects the merchant’s website or point-of-sale (POS) system to the acquiring bank. It securely transmits transaction data.
- Payment Processor: A company that handles the technical aspects of processing card payments, such as authorization, clearing, and settlement. Often, the acquiring bank also acts as the payment processor.
The Card Processing Workflow
The card processing workflow can be broken down into several key steps:
-
Authorization:
- The cardholder presents their card to the merchant for payment, either physically or online.
- The merchant’s POS system or payment gateway transmits the transaction information (card number, expiration date, amount) to the acquiring bank.
- The acquiring bank sends the authorization request to the card network.
- The card network routes the request to the issuing bank.
- The issuing bank verifies the cardholder’s account balance and available credit.
- If sufficient funds are available, the issuing bank approves the transaction and sends an authorization code back through the card network to the acquiring bank and then to the merchant.
- If the transaction is declined, the issuing bank sends a decline code, and the merchant is notified.
-
Batching:
- Throughout the day, the merchant accumulates authorized transactions in a batch.
- At the end of the day or at a predetermined time, the merchant submits the batch to the acquiring bank for settlement.
-
Clearing:
- The acquiring bank sends the transaction details to the card network.
- The card network clears the transaction by debiting the issuing bank and crediting the acquiring bank.
-
Settlement:
- The issuing bank transfers the funds to the card network.
- The card network transfers the funds to the acquiring bank.
- The acquiring bank deposits the funds into the merchant’s account, minus any fees.
Types of Card Processing Systems
Card processing systems can be categorized based on the payment environment:
- Point-of-Sale (POS) Systems: These systems are used in brick-and-mortar stores and restaurants. They typically involve a physical terminal that reads the card information, either through a magnetic stripe, chip (EMV), or contactless (NFC) technology.
- Online Payment Gateways: These systems are used for e-commerce transactions. They provide a secure interface for customers to enter their card information online. Examples include PayPal, Stripe, and Authorize.net.
- Mobile Payment Systems: These systems allow merchants to accept payments using mobile devices, such as smartphones or tablets. They often involve a card reader that connects to the device.
- Virtual Terminals: These systems allow merchants to manually enter card information into a web-based interface. They are often used for phone orders or mail orders.
Security Measures in Card Processing
Security is paramount in card processing to protect cardholder data and prevent fraud. Several security measures are in place:
- PCI DSS Compliance: The Payment Card Industry Data Security Standard (PCI DSS) is a set of security standards designed to protect cardholder data. Merchants and service providers that handle card payments must comply with PCI DSS.
- Encryption: Encryption is used to protect cardholder data during transmission and storage. Data is converted into an unreadable format, making it difficult for unauthorized individuals to access.
- Tokenization: Tokenization replaces sensitive cardholder data with a unique, randomly generated token. The token can be used to process transactions without exposing the actual card number.
- Address Verification System (AVS): AVS verifies the cardholder’s billing address against the address on file with the issuing bank. This helps to prevent fraud by ensuring that the person using the card is the legitimate cardholder.
- Card Verification Value (CVV): The CVV is a three- or four-digit security code printed on the back of the card. It is used to verify that the person using the card has physical possession of the card.
- 3D Secure Authentication: 3D Secure (e.g., Verified by Visa, Mastercard SecureCode) adds an extra layer of security to online transactions by requiring the cardholder to authenticate themselves with the issuing bank.
- Fraud Monitoring: Payment processors and acquiring banks use fraud monitoring systems to detect and prevent fraudulent transactions. These systems analyze transaction data for suspicious patterns and flag potentially fraudulent transactions.
Fees Associated with Card Processing
Merchants are typically charged fees for card processing services. These fees can vary depending on the type of card, the transaction volume, and the merchant’s agreement with the acquiring bank. Common types of fees include:
- Interchange Fees: These fees are paid to the issuing bank for each transaction. They are typically a percentage of the transaction amount plus a fixed fee. Interchange fees are set by the card networks.
- Assessment Fees: These fees are paid to the card networks for the use of their network. They are typically a small percentage of the transaction amount.
- Processing Fees: These fees are charged by the acquiring bank or payment processor for processing the transaction. They can be a percentage of the transaction amount, a fixed fee per transaction, or a combination of both.
- Statement Fees: Some acquiring banks charge a monthly fee for providing statements.
- Chargeback Fees: These fees are charged when a cardholder disputes a transaction and the merchant is required to refund the money.
- PCI Compliance Fees: Some acquiring banks charge a fee for helping merchants comply with PCI DSS.
Choosing a Card Processing System
When choosing a card processing system, merchants should consider the following factors:
- Pricing: Compare the fees charged by different providers. Look for transparent pricing with no hidden fees.
- Security: Ensure that the provider has robust security measures in place to protect cardholder data.
- Integration: Choose a system that integrates seamlessly with your existing POS system or e-commerce platform.
- Customer Support: Look for a provider that offers excellent customer support.
- Reporting: Choose a system that provides detailed reporting on your transactions.
- Contract Terms: Carefully review the contract terms before signing up for a card processing service.
Future Trends in Card Processing
