Unified Payment Interface (UPI)

Unified Payment Interface (UPI) is a revolutionary real-time payment system developed by the National Payments Corporation of India (NPCI) and regulated by the Reserve Bank of India (RBI). It enables seamless and instant fund transfers between bank accounts using a mobile device. UPI has gained immense popularity in India due to its simplicity, speed, and convenience.

Key Features of UPI:

  1. Instant Transfer: Funds are transferred in real-time, 24/7, including weekends and holidays.
  2. Interoperability: Facilitates transactions between accounts of different banks.
  3. Single Identifier: Users can perform transactions using a Virtual Payment Address (VPA), mobile number, or QR code, avoiding the need to share sensitive bank details.
  4. Small and Large Transactions: Supports micro-payments as well as larger transfers, depending on daily limits.
  5. Multiple Accounts: A single UPI app can link multiple bank accounts for easier management.
  6. Low Cost: UPI transactions are either free or charge minimal fees, making it cost-effective.

How UPI Works:

  1. Registration:
    • Download a UPI-enabled app (e.g., Google Pay, PhonePe, Paytm, or BHIM).
    • Link your bank account to the app using the mobile number registered with your bank.
    • Set up a Virtual Payment Address (VPA) and a UPI PIN.
  2. Transaction Process:
    • To send money: Enter the recipient’s VPA, mobile number, or scan their QR code. Specify the amount and confirm with your UPI PIN.
    • To receive money: Share your VPA or generate a QR code.
  3. Validation:
    • The system validates the details and processes the transaction instantly.
