Example 1:Seamless in-app payment within the same mobile of the user.
Ashok is a student and uses a video application (MyStar) that allows buying on-demand movie on his
Android phone.
He banks with DiBank (PSP in this case)and uses their mobile application for Android that has implemented UPI features.
In MyStar app, Ashok wants to watch a movie for Re.25.
MyStar application creates the UPI payment link as per this spec and launches the Android intent with all necessary parameters populated in the URL.
Since DiBank PSP app is registered to listen to UPI link/intent, it starts the app and takes Ashok straight to pay screen with all values pre-populated from the link/intent.
Ashok verifies the info on screen and click pay to complete the payment
