How does a payment gateway work? What is the mechanism?


An internet connection is a must for processing any amount using a payment gateway. A buyer puts up the selected item in the shopping cart and places the buy now option. You get navigated to the page where you need to fill up the basic credit card and other details in the form.

The payment gateway processes the information and sends it across to the respective bank. After proper verification, as soon as the bank approves the payment, the amount gets debited from the customer’s account and credits into the seller's account.

There are certain things that you need to consider before you proceed for payment gateway integration.

Seller Account Types:

A seller account is an account where the money is transferred once the customer pays. A seller has two account options to choose from, first is a dedicated account and the second is an aggregated merchant account.

A dedicated account gives the seller complete control over the financial activities. It is a devoted account that allows you to correct any financial errors in the entry and allow you to claim a chargeback. Needless to say, this account type is more expensive and time-consuming.

On the other hand, aggregated merchant accounts hold the funds of multiple sellers. It is a faster and better approach because it releases the funds usually within 24 hours. It is less expensive but at the same time, less secure than the dedicated account type.

The Products you want to sell:

The products you want to sell on the app have a lot to deal with the decision of mobile app payment gateway integration. The reason being, physical goods payment processing is different from digital goods payment processing.

The payment approach for physical goods is easy and approachable, but with digital products, it is a different story. Android and iOS platforms do not allow merchants to use third-party eCommerce payment services. Payment gateway integration in iOS and Android apps is platform-specific. The transaction is performed using the respective individual’s platform-specific account which further connects with the payment gateway.

Security Compliances:

Usually, almost all the payment gateways available provide a security certificate that ensures the users’ data security. However, before selecting the gateway for your application, check the PCI DSS compliance certificate issued by the payment gateway officials.

To receive the security compliance certificate, you need to design the app that meets the PCI DSS standards. This is to ensure that you meet the required standards of protecting sensitive credit card/debit card information. The officials will review and audit the system and the organization. If found compliant, the certificate will be issued to you.
