UPI (Unified Payments Interface)

What is UPI?

Unified Payments Interface (UPI) is a real-time payment system developed by the National Payments Corporation of India (NPCI) that enables instant money transfers between bank accounts using a mobile device. UPI works 24×7, including on holidays, and supports features like bill payments, QR-based transactions, and merchant collections.

How UPI Works

  • Link multiple bank accounts to a single mobile app (like PhonePe, Google Pay, Paytm, etc.)
  • Use a Virtual Payment Address (VPA) instead of IFSC/account number
  • Transfer funds instantly across banks
  • Authenticate payments via UPI PIN
  • Make payments using UPI QR codes or collect requests

It uses IMPS infrastructure, ensuring real-time settlements.
