Types of Payment Gateways

Digital transactions have enabled people to have a fantastic and effortless journey towards cashless transactions. The merchants always strive to make the whole experience a secure, flexible, and accessible one. And, payment gateways have played a significant role in keeping the transaction safe and ensuring customer satisfaction.

There are different types of payment gateways.

Self-Hosted Payment Gateway Integration

It is the most effortless payment method. A self-hosted payment gateway enables the customers to pay for the service or goods without leaving the site. Furthermore, this payment gateway intervention allows the merchants to accept the online payment from the customers on the site itself. Here the payment can be self-hosted by the merchant who controls the entire checkout process. However, since the merchant entirely controls this whole process, this implies that he even has to take extensive safety measures to protect his customer’s card or transaction details.

API or Non-Hosted Payment Gateway Integration

This payment gateway enables customers to carry out their payment directly on the checkout page by entering their transaction details. The process conducts the transaction using API. This payment gateway is similar to the self-hosted method, where merchants have complete control over the payment page user interface. However, there is no redirection involved. Therefore, it is a non-hosted payment gateway and gives the customers a one-page checkout experience.

Payment Gateway Integration or Payment After Redirection

This method redirects users to a page where they can further proceed with the payment by entering the required details of debit card, credit card, UPI, net banking, and even wallets. Here, the gateway acts as a third party as the customer has to leave the merchant’s site to proceed with the payment. It is the most common type of payment gateway method used by most startups and companies. The only disadvantage here is that the merchant has no control over the entire process and has no management or influence on the customer experience during the transaction process.

 When it comes to the functions of payment gateways, different payment gateways work differently. Therefore, when choosing the convenient payment method, it is better to consider the following factors:

  • Details about any transaction fees. Suppose there is a transition fee associated with the payment gateway, then the specific payment gateway charges a small fee for further processing the transaction. 
  • The sign-up process of the payment gateway, if it promises a secured transaction.
  • Always read the terms and conditions of the payment gateway to determine the type of services it provides and supports for selling. 

Components in Future Payment Gateways

With the extreme development and inventions in the science and technology sector, biometric authentication has advanced dramatically. Biometric data is considered more reliable and safer. Moreover, because the biometric data of each person is unique, there is no possibility of imitation. As such, it is vital to integrate it as a payment gateway safety measure in the future.

Artificial Intelligence

In the future, incorporating artificial intelligence in the services provided by payment gateways will offer more convenience in the process.


Incorporating blockchain technology in payment gateways will make it highly safe and secure. Moreover, identity-based blockchain uses an immutable ledger to store information and cross-verify collected data of the transactions, thus decentralizing data collection. Doing this reduces the risk of a security breach and further enhances the reliability and efficiency of payment gateways.

Voice transaction

As the emergence of voice technology has been influencing the customer’s attitude, merchants or retailers are now incorporating voice commerce in their company, enabling them to communicate with the customers using voice technology. It may further enhance the customer’s experience while carrying out a transaction with the retailer or the company.


As for the future of payment gateways, there is no doubt that it will be at any disadvantage of its growth. The growth of the eCommerce industry has allowed merchants to expand their startups and services over the digital network.

It has also paved the foundation for future advancements and growth in payment gateways. Payment gateway services, with evolving epoch, are expected to advance more than the present scenario, making them an integral part of any company’s success in the future.
