Top Payment Gateways
June 4, 2021


If you are planning to start an exciting business and want to make it a customer-centric brand, you would definitely face challenges while finding the best Payment Gateway to integrate into your mobile app.

On the other hand, if you are unhappy with the already integrated payment gateway into your app, and want to drive a change without compromising on quality and overall performance, then this post will definitely help you out with the same. Let’s initially understand what a payment gateway is.

Payment Gateway: What is that?

A payment Gateway is software that collects payment from the customers and transfers it to the recipient. A payment gateway validates customer’s card data securely, checks that money is there, and ultimately facilitates merchants to get the money.

These gateways are acting as an interface among merchant apps/websites and purchasers. It encrypts customer’s confidential card details by assuring that data passed with maximum security from customers to the bank through merchants.

What is the Role of a Payment Gateway?

Besides the key role of authenticating different transactions, a PG performs additional major tasks.

  • With high security, it stores all the confidential details of customers for future transactions.
  • Accept multiple methods for online payments.
  • Streams different transactions in complete safety.
  • Preserves a steady channel without any interruptions to send funds from the bank accounts of the cardholder to the receiver.
  • Streamline the payment process to pay effortlessly.

How Do Payment Gateway Functions?

Customers will be transferred to a secure payment page while checking out. Various steps take place throughout the transaction process.

  • A user/customer initiates a payment after submitting an order.
  • Vendors transfer order information to Payment Gateways.
  • Then a transaction is forwarded to the issuing bank or the 3D secure page to demand transaction authentication.
  • After successful authentication, a transaction is approved or rejected by the bank or card (Visa, Master, Maestro, American Express) based on the availability of funds in the account.
  • Payment Gateway notifies merchants of the same by sending an SMS accordingly.
  • The bank then fixes the fund with Payment Gateway, and Payment Gateway fixes the fund to the vendors.
