What is UPI for my bank account?

UPI, or Unified Payments Interface, is a mobile payment system developed by the National Payments Corporation of India (NPCI) that allows users to securely transfer money between bank accounts using a smartphone application. Your UPI ID is an address that identifies you on this system, often in the format of a name, mobile number, or email part, followed by "@bank" or "@paytm" if using Paytm's services, linking directly to your registered bank account for seamless transactions.
