A payment gateway is an e-commerce application that enables payments for modern retail and several types of sales by transferring information between payment portals. It is a wise and an efficient replacement to cash transactions. The benefit of this virtual paying method is that the sensitive information is encrypted. For example, credit or debit card number, pin code, etc. This ensures safe as well as easy exchange of information between the customers and the merchant. Through this, the customers and vendors stay connected to each other as well as their respective banks.
