A UPI app is a mobile application that uses the Unified Payments Interface (UPI) system to facilitate instant, real-time fund transfers between bank accounts. Regulated by the Reserve Bank of India (RBI) and developed by the NPCI, these apps allow users to:
- Link multiple bank accounts to a single platform.
- Send and receive money instantly using a UPI ID, mobile number, or QR code.
- Pay utility bills and make merchant payments 24/7.
- Secure transactions using two-factor authentication and a secure UPI PIN.
