Introduction to Payment Gateways

What is a Payment Gateway?

A payment gateway is a service that processes credit card payments for online and offline businesses. It acts as an intermediary between the customer and the merchant, ensuring secure transactions.

Note: Payment gateways are essential for e-commerce websites to facilitate secure online payments.

How Payment Gateways Work

Payment gateways work by securely capturing and transmitting payment information from the customer to the payment processor.

Step-by-Step Process:

  • Customer selects products and proceeds to checkout.
  • Customer enters payment details on the checkout page.
  • The payment gateway encrypts the data and sends it to the payment processor.
  • The payment processor communicates with the bank to authorize the transaction.
  • The response is sent back through the gateway to the merchant.
  • The merchant completes the order based on the transaction response.
