1. What is a Payment Gateway?

A payment gateway is a technology that allows online transactions by securely transmitting payment information between the customer, merchant and a bank. It acts as a digital version of the point-of-sale (POS) terminal found in bricks-and-mortar shops. Payment gateways ensure transactions are safely processed efficiently, and in real-time.

The main functions of a payment gateway comprise:

Authorizing payments.
Securely encrypting sensitive data such as credit card information.
Ensuring compliance with financial regulations.

2. How Payment Gateways Work

Payment gateways operate under the hood to ensure seamless transactions. This is a step-by-step guide on what they do:

The customer initiates a transaction: A customer selects a product or service and then proceeds to the payment page on a website or mobile app.
The Payment Information is entered: The customer provides the details of their payment like credit card information or opts to use an alternative way to pay, like a digital wallet.
Secure and Encryption: The payment processor encrypts the customer’s details to guard against fraud and securely transmits the information to the bank that pays for the transaction.
Authorization Request The bank that is acquiring sends the payment request to the issuing bank of the customer to obtain the authorization.
Answer from Issuing Bank: The issuing bank approves or declines the transaction based on the state of the account of the customer or funds in the account, as well as other factors.
Transaction Finalization The payment gateway transmits its response directly to the vendor. If approved, the transaction has been completed and funds are transferred to account of the merchant.

This entire process typically happens within seconds, ensuring a seamless experience for both the customer and the merchant.
