Sarvatra UPI app provides a white-label PSP Mobile Application on iOS and Android platforms.

It supports all UPI transactions and virtual address management.

The mobile application server is the front-end web server that accepts requests from mobile devices, forwards them to the UPI switch, and passes back the responses received from the switch.

It is separate from the UPI switch so that it can be deployed in the demilitarised zone of the bank’s internet firewall.

It works on standard web servers like Tomcat, WebLogic, JBoss, etc.
The objective of NPCI’s Bharat Bill Payment System (BBPS) is to implement an integrated bill payment system in the country that offers interoperable and accessible bill payment services to customers through a network of agents, enabling multiple payment modes, and providing instant confirmation of receipt of payment.
