UPI is a payment interface, not a value that requires a mathematical calculation. It is a real-time system developed by the NPCI for instant money transfers between bank accounts. Instead of calculating a value, users perform transactions by:
- Entering the recipient's UPI ID or mobile number.
- Scanning a Bharat QR code.
- Inputting the specific transaction amount in Indian Rupees.
- Authorizing the payment using a secure UPI PIN.
There are no additional charges for standard peer-to-peer transactions.
