The introduction of the UPI system is one of the best things today, and this App by the government claims to be very secure, so far that seems to be true for me as I have been a very very frequent user of it.
The concept of the application is very nice, I can literally do cashless transaction with this, since I am so busy this days I dont have the time to visit banks now and then, so a lot of work starts to pile up, so without the need of going to bank this app can handle all the tasks like sending and receiving money to anyone, anytime and from anywhere to any bank hence its very useful and secure.
The best thing apart from being secure is that the design and layout of this application is very simple, with minimal graphics, so its light weight and easy to use, honestly I am not a fan of bulky gimmicks as they could be trouble some during important work, so this app is very neat.
There are three different ways by which money could be sent, directly by UPI ID, Phone number, or by selecting bank details etc, theres option to save the contact for future purpose as well, one more thing I liked is the timer option which allows the user to send money to a particular contact regularly on timely intervals. Also you I am able to check the balance in my account with ease, and for security it has double passwords, one in the beginning and one during the transaction so its very secure.
The usefulness of this app is great, as it has made cashless transaction a lot easier and simpler for me, so I would definitely recommend this.
