Let's understand more about the UPI facility
What is UPI?
Unified Payments Interface or UPI is a system that powers multiple bank accounts into a single mobile application (of any participating bank), merging several banking features, seamless fund routing & merchant payments into one hood. UPI lets your mobile phones function as a debit card, and you can use it to do real-time bank to bank transfers. All you need is a UPI id and the PIN to make financial transactions within minutes.

UPI was initiated by the National Payment Corporation of India (NPCI). The Reserve Bank of India (RBI) and the Indian Banks Association (IBA) were part of its initiation. The NPCI also initiated IMPS, or Immediate Payment Services, but the UPI is a more advanced version of this IMPS.

How does UPI work?
Just a few years ago, transferring money to a bank account used to be a complicated process. However, UPI has made the process easy and smooth. Now, you don't need too many details to send money; all you need is the receiver's UPI id or the mobile number registered with the UPI id.
Setting up a UPI id is simple and requires one to follow a few simple steps. First of all, install an app that supports the UPI services, and then provide the required details of your bank account. You will receive an OTP on the mobile number linked to your bank account. Once it is verified, you will be asked to create a PIN. Don't share the PIN with anyone. Once the process of creating the UPI id is completed, you will be able to view your UPI id, which is in the format of "(mobile number)@(the app)".
