| What is Payment Gateway : An Insight into the Lifeblood of Internet Money Transfers |
A payment gateway But what is a payment gateway? What makes it such a significant part of the e-commerce system? What is its functioning and how businesses select the appropriate one? It is a clear and complete response to all those questions and many more, in this blog post.
What is a Payment Gateway?
A payment gateway is an online facility that authenticates and accepts payments between an organization and a customer. It is the digital intermediary between the payment account of the buyer (e.g. credit card or digital wallet) and the bank account of the seller.
It is sort of a computerized point-of-sale terminal on the internet. But, in the e-commerce world it is slightly more complicated and very safe, and consists of a number of steps and systems that communicate with each other, in real-time.
The main idea is that once a customer made a purchase online, the payment gateway securely encrypts the information and sends the transaction to the bank requesting authorization thus approving or rejecting the payment when it takes place in a few seconds, which is a basic explanation in simple terms.
Why is a Payment Gateway Important?
A payment gateway cannot be ignored by any business that wishes to sell products or services online. Here’s why:

| Why is a Payment Gateway Important? |
Security: Payment gateways make sure that all the information of the transaction is encrypted and securely sent so that a user is not affected by fraud and theft of information.
Ease of use: Customers can pay in several ways- credit/debit cards, net banking, wallets, UPI or even using crypto, and this happens through a single interface.
Speed: The transactions occur in real-time, enhancing the user experience and cutting down cart abandonment rates.
Scalability: A high-quality gateway should be able to support hundreds or thousands of transactions per second, and therefore such a gateway could be used by both small startups and big businesses.
How Does a Payment Gateway Work?
Although the whole process of the transaction might look easy on the surface, it actually takes a great number of steps backstage:
Customer Checkout: A customer selects a product, puts them into the cart and proceed to the checkout page.
Submission of Payment Details: The customer provides their payment details- like card details or they will choose a wallet/UPI.
Encoding: The payment gateway encodes the sensitive information to safeguard it in the course of transmission.
Transaction Requested: The gateway sends this message to the acquiring bank (merchant bank).
Card Network Communication: The acquiring bank sends the contact to the applicable card network (such as Visa or MasterCard).
Authorization of Issuer: The card network sends the request to the issuing bank (bank of the customer) to permit or reject the transaction.
Answer: The answer (accepted/refused) is returned to the gateway through the same channel.
Completion: Once the approval has been accepted the merchant is confirmed and the product/service is delivered.
And it all goes on in real-time, sometimes within 2 3 seconds!
