Its a support to digital India, Introducing digital or cashless India.
This app is very responsive and design is good mean easy to use.
The feature I like is the speed of transactions:
First of all to use this app you need an active bank account with mobile number linked to it and the bank should support UPI based payments. Paying through the app pretty simple just enter the mobile number or the aadhar number of recipient and then enter amount and pin and thats it. its done money sent successfully and the same second of time the money is deposited in the recipients account.
Using this app in every possible areas and its very helpful.
