The online payment process involves several key steps that work together seamlessly. First, the customer enters their payment details at checkout, which are securely encrypted and transmitted to the payment gateway. The gateway forwards this information to the cardholder’s issuing bank for authorization. The bank checks the customer’s available funds or credit and performs fraud prevention checks. If the transaction is approved, the bank sends an authorization code back to the gateway, confirming the payment. The merchant then processes the order and prepares the goods or services for delivery. Meanwhile, the payment is transferred from the cardholder’s bank to the merchant’s acquiring bank, which processes the payment. Finally, the acquiring bank deposits the funds into the merchant’s account, completing the transaction. This process typically occurs in a matter of seconds, ensuring a quick, secure, and efficient experience for both the customer and merchant.
