A unique UPI ID is created by using your phone CV number that is linked to your bank account.
This ID is just like an ordinary email ID. For example if your mobile number is 123456789 and you have a bank account with the Punjab National Bank, your UPI id may be123456789@PNB.
To send money from any party, all the sender has to do is open the banking app installed in his or her phone, go to ‘Send money’ section, and facilitate transactions through UPI mode. In the recipient details, the sender needs to add id of the recipient (for example123456789@PNB).
The money gets transferred instantly to the bank account of the recipient once approved by the sender.
