What is UPI?

UPI stands for Unified Payments Interface, which is like a magic digital wallet that lets people in India send money to each other instantly using just their phone [2]. It's similar to how you might hand money to a friend, except everything happens through your phone and the money moves between bank accounts in seconds [2].

Why was it created?

Before UPI, sending money to someone in India was slow and complicated, kind of like waiting in a long line at a store [2]. The Indian government created UPI in 2016 to make payments super fast and easy for everyone, even people without fancy bank apps [2].

How do you use it?

You download an app on your phone, link it to your bank account, and then you can send money to anyone else using UPI by just typing in their special UPI address (like a username) [2]. It works instantly, day or night, which is much faster than old-fashioned bank transfers [2].

What makes it special?

UPI is so popular in India because it's free or very cheap to use, works on any phone, and you don't need to remember complicated bank details—just a simple address [2]. Millions of people in India use it every single day instead of carrying cash around [2].
