What is UPI ID - Meaning, Full Form and Transaction Limit

What Is UPI?

The UPI full form is Unified Payment Interface. It is a system that integrates various bank accounts, efficient fund routing, and merchant payments into a single mobile application of any bank that takes part in the integration. Additionally, it supports "Peer to Peer" collect requests, which can be planned and paid for according to the need and convenience of the user. One can do all this without providing the IFSC code or account numbers. The Rupay payment feature of the UPI acts as a platform for multiple banks to interconnect and transfer funds seamlessly. 

How Is UPI Unique

  • Enables Real-Time Money Transfer

The most distinguishing feature of UPI payments is that it enables the real-time transfer of funds around the clock. Users can use UPI apps anytime to cater to their payment needs, unlike NEFT or bank deposits and withdrawals. 

  • No Hassle Money Transfer

A smartphone with a UPI app, a stable internet connection, and a bank account are all needed to send and receive funds. Users can send money across different accounts using this interface and access their own multiple accounts through a single app on their smartphones. 

  • Two Factor Authentication

UPI offers two-factor authentication (2FA), which adds an extra layer of protection by incorporating biometrics, security tokens, and one-time passwords, as opposed to single-factor authentication, which requires users to submit only one element, generally a password or PIN. 

  • VPA Support

A UPI app's Virtual Payment Address (VPA) is a special ID you need to complete payments. This VPA serves as additional protection because it does not require you to provide additional personal or bank information. The user's bank information will only need to be entered occasionally, except at the time of linking the user's bank account to the UPI app.

  • Good Substitute For Cash

It is a very helpful substitute for the inconveniences of Cash on Delivery or rushing to an ATM to get cash to make payments. Moreover, users can pay the exact amount, which alleviates the problem of getting and giving change.

  • Keep track of Splitting Bills With Friends

It's not just a solution for hassle-free payment but also has a feature to add expenses, split your bills among your friends, and share it with them within the app itself.

How Does UPI work?

UPI primarily functions on a smartphone and a bank account with a UPI-member bank. With these two essentials in hand, you need to create your UPI ID and PIN to start transferring and receiving. You should register your smartphone's SIM linked with your bank account. 

UPI identifies the bank account you have linked to the UPI account, which will send or withdraw money for transactions. A 4-digit PIN or Personal Identification Number is to be set by the user to authorize the money transaction that is to take place. The account holder may select this PIN. Here is a stepwise guide to set up your UPI. 

  1. Download any UPI payment app like GooglePay, PhonePe, BHIM, or Paytm from the App Store (iPhone users) or PlayStore (Android users). 
  2. Create a virtual ID that will serve as the unique ID to transfer and receive payments. 
  3. Set your UPI-PIN, which will be your phone's unlock pin by default.
  4. Verify your bank details by entering and linking the OTP generated to the app.
  5. You will now be able to set up your Virtual Payment Address. 
  6. Set your mPIN, which will be asked before processing each transaction.

Once your account is set up, you can now make payments to others either by entering the virtual payment address (VPA) of the receiver, account number and IFSC code, registered phone number, or QR code as per the availability and need.
