Let us find out what is UPI in this article.

What is UPI Payment? (UPI Full Form and Meaning)

UPI means Unified Payment Interface. It is an application that runs on internet-enabled smartphones. Developed by the National Payments Corporation of India, UPI is a real-time, single-window payment application. In simple words, UPI means a payment interface that allows you to transfer funds from one bank account to another bank account in real-time. With UPI, you do not need to collect or share your sensitive bank information such as your account number, IFSC, bank branch and bank name every time you wish to transfer money. At present, almost all banks in the country are a part of the UPI network.

You can use the UPI platform to transfer money to your family members, friends, colleagues, acquaintances, or practically anyone with a UPI ID. The system directly transfers money to their bank account. Similarly, you can receive funds in your bank account by simply sharing your UPI ID. UPI essentially allows you to transfer funds safely, securely, and seamlessly without revealing any bank-specific information.

How Does UPI Work?

UPI (Unified Payments Interface) links multiple banks on a single platform for instant fund transfers.  Users create a UPI ID (virtual payment address) instead of sharing bank details.

Transaction flow:

  • Enter recipient’s UPI ID, mobile number, or scan QR code.
  • Authenticate using UPI PIN.
  • Sender’s bank sends the request via NPCI to the recipient’s bank.
  • Recipient’s bank approves, and money is credited instantly.

UPI uses end-to-end encryption and two-factor authentication for security. It Works 24x7 for peer-to-peer, merchant, and bill payments via the IMPS network.

What is UPI PIN?

A UPI PIN is a 4- or 6-digit personal identification number that authenticates transactions through the UPI platform. It acts like a password, ensuring that only the account holder can approve payments. Every UPI transaction requires entering your UPI PIN, which keeps your funds secure even if someone gains access to your mobile device.

How to Generate or Reset a UPI PIN?

Generating or resetting a UPI PIN is simple and can be done via your UPI-enabled banking app:

Step 1: Open your bank’s UPI app and select the account you want to link.

Step 2: Choose the option to generate or reset your UPI PIN.

Step 3; Enter your debit card details, including the expiry date.

Step 4: Set a new 4- or 6-digit UPI PIN and confirm it.

Step 5: Your UPI PIN is now ready for secure transactions.

How to Find My UPI ID?

To find your UPI ID, follow these simple steps:

Step 1: Open your UPI-enabled banking app.

Step 2: Go to the UPI or profile section.

Step 3: Locate your UPI ID / Virtual Payment Address (VPA).
