As a consumer, credit card transactions seem deceivingly simple. You swipe the card or click the pay button, and a few seconds later, you get an order confirmation. What goes on behind the curtain, however, is quite a bit more complex. Read on to learn more about the key participants in credit card transactions and each stage of this process.

The Key Participants

Even though credit card transactions are processed within seconds, the number of parties that participate in this process is surprisingly large. They include:

• Cardholder: Individual who uses a credit card to initiate a transaction
• Merchant: Business or service provider that accepts credit card payments
• Point-of-sale (POS) system: Hardware the merchant uses to process payments
• Payment gateway: Service that transmits transaction data to the payment processor
• Payment processor: Company that authorizes and authenticates transactions
• Card network: Association that routes transactions between banks
• Issuing bank: Institution that issued the credit card to the cardholder
• Acquiring bank: Institution that processes the transaction for the merchant

The Anatomy of a Credit Card Transaction

Each credit card transaction consists of five distinct stages. These are:

1. Authorization

Once the cardholder initiates the transaction, the merchant’s POS system or payment gateway transmits this data to the payment processor. The processor sends the data to the appropriate card network, which forwards it to the issuing bank for authorization. Once the issuer verifies the cardholder’s account balance and fraud risk, they’ll approve or decline the transaction.

2. Authentication

To prevent fraud, there are several security measures incorporated into each transaction:

• EMV chip technology: Provides dynamic encryption for each transaction
• 3D Secure authentication: Another verification step for online transactions
• PCI DSS compliance: Ensures the merchants adhere to the PCI DSS standards
• Tokenization: Converts sensitive transaction data into unique tokens

3. Clearing and Settlement

At the end of the business day, the merchant will submit each authorized transaction to their acquiring bank for further processing. The bank routes the transactions to card networks, which forward them to the issuing banks. The issuing bank deducts the correct amount from the cardholder’s balance, and this amount eventually gets to the merchant’s account.

4. Dispute Resolution

If a cardholder disputes a transaction, they may contact the issuing bank to dispute the charge. The issuing bank will investigate the matter, temporarily crediting the cardholder. Once the merchant is notified about this, they’ll be able to provide evidence to refute the dispute. If the dispute is resolved in the cardholder’s favor, the merchant will absorb the charge.

5. Reconciliation

Finally, merchants and banks will reconcile their transactions and generate the relevant reports:

• Settlement reports: Reviewing settled transactions
• Chargeback reports: Tracking disputed transactions and their resolution status
• Fraud detection reports: Using AI systems to analyze suspicious transactions
