The Process of Card Authorization and Capture

Card authorization and capture is a crucial step in the payment process for merchants and customers alike. It ensures that the customer's payment information is valid and that the merchant can securely process the payment. In this article, we will delve into the details of how card authorization and capture work, from start to finish.

Authorization

The first step in the card authorization and capture process is authorization. When a customer initiates a payment, either online or in-store, their payment information is sent to the payment gateway. The payment gateway acts as a middleman between the merchant's system and the acquiring bank, which is the bank that processes the payment.

The payment gateway securely transmits the customer's payment information, including the card number, expiration date, and CVV, to the acquiring bank. The acquiring bank then sends this information to the card network, such as Visa, Mastercard, or American Express.

The card network receives the authorization request and performs a series of security checks, including verifying the validity of the card, the availability of funds, and the presence of any fraud alerts. Once the card network approves the authorization request, it sends an authorization code back to the acquiring bank.

The acquiring bank then forwards the authorization code to the payment gateway, which relays it to the merchant's system. The merchant's system can now proceed with the capture process.

Capture

After receiving the authorization code, the merchant's system can initiate the capture process. This process involves the settlement of funds from the customer's account to the merchant's account.

The merchant's system submits a capture request to the payment gateway, along with the authorization code and the desired amount to capture. The payment gateway, in turn, sends the capture request to the acquiring bank.

The acquiring bank processes the capture request and initiates the transfer of funds from the customer's account to the merchant's account. The acquiring bank also deducts its fees from the captured amount. Once the capture is successful, the acquiring bank sends a confirmation back to the payment gateway.

The payment gateway relays the capture confirmation to the merchant's system, indicating that the payment has been successfully processed. At this point, the transaction is considered complete, and the merchant can proceed with fulfilling the customer's order.

Void and Refund

In some cases, the merchant may need to void or refund a transaction. A void is typically performed when the merchant needs to cancel an authorization before the capture process occurs. This can happen if the customer changes their mind about the purchase or if there are any issues with the order.

A refund, on the other hand, is performed after the capture process has completed. A refund can be initiated if the customer requests to return the purchased item or if there was an error in the transaction. The merchant's system sends a refund request to the payment gateway, which then forwards it to the acquiring bank for processing.

The acquiring bank processes the refund request and initiates the transfer of funds from the merchant's account back to the customer's account. Once the refund is successful, the acquiring bank sends a confirmation back to the payment gateway, which relays it to the merchant's system.

Conclusion

Card authorization and capture are crucial steps in the payment process, ensuring the security and validity of transactions. By understanding the process, both merchants and customers can have confidence in the payment system and enjoy a seamless purchasing experience.
