There is a lot to consider when starting an eCommerce website. After building the site and implementing a shopping cart where users can store the products they want to buy, you will need to figure out a way to accept payment and confirm the order. This is where a payment gateway becomes a must. This article will explain what a payment gateway is and the steps it will take to process payments from potential customers.
The payment gateway is a service that solves the complex and technical process of encryption and verification of the customer's payment card and the subsequent transfer of funds from the customer to the merchant. The payment gateway works in the background of the website and the user will never interact with it directly.
Instead, the user will generally be redirected to the checkout page, where the merchant can request the relevant data regarding the customer's name, address and payment card details.
