Payment Gateway – What is it?

A payment gateway represents a software app or service that manages credit cards and other transaction forms for e-commerce retailers and businesses in the same manner as a POS system does for a physical store.

A payment gateway’s primary mission is to handle credit card information of online customers dropping to your e-commerce store.

To guarantee that credit cards and other payment methods are safe and that the transaction between both the retailer and the client is effective, the application must be able to secure payment information.

Although the theory might be simple, some of the processes aren’t. The payment processing program must be able to send transaction details for authorization to the correct source and then transmit the request back to the store.

That’s how the store knows whether the transaction is approved or denied.

The main reason you need a payment gateway

If you have a current website or you are planning to have one in the future that will accept online payments, you will definitely need a payment gateway. One explanation is that all online credit card transactions are actually being done through payment gateways. There are no other viable options. Moreover, in order to authorize the orders of your customers and to obtain your money, you must have one. You will also need one if you intend to receive payments using a mobile device.
