Working of Payment Gateway
Though it may sound simple but actually the entire working of a payment gateway comprises of multiple complex steps; a brief of which is given below:
Visitor places the order on the website and it is sent to the merchant's web server in encrypted format. This is usually done via SSL (Secure Socket Layer) encryption. The transactions details are then forwarded to the concerned Payment Gateway. The transaction information is then passed on to the merchants acquiring bank by the Payment Gateway.
Merchants acquiring bank then forwards the transaction information to the issuing bank (one that issued the credit card to the customer). Then the card issuing bank sends a response back to the Payment Gateway. The response includes information that whether the payment has been approved or declined. In case of declination the reason is also sent in the response. The response is then forwarded by the Payment Gateway to the merchant's server. At merchants server the response is encrypted again and is relayed back to the customer. This allows the customer to know that whether the order has been placed successfully or not.
The entire process typically takes less than 5 seconds. At the end of the bank day (or settlement period), the acquiring bank (or card issuing bank) deposits the total of the approved funds in to the merchant's nominated account
