Unified Payments Interface History

The Unified Payment Interface or UPI is India's fast and secure digital payment system. Launched in 2016 by the National Payments Corporation of India (NPCI), a government-backed institution set up to unify and simplify digital payments across the country. Initiation of the UPI probably worked around 2012, when the idea was to minimize cash usage and ensure that digital payments were easy and inclusive for all, including for people without any bank access.

Before UPI, banking and payments were slower and less integrated. The RBI (Reserve Bank of India) and the NPCI came together to design a platform for instant money transfers directly from bank accounts to bank accounts, via smartphones, without long procedures to furnish account details. UPI functions as a layer on pre-existing Immediate Payment Service (IMPS) and provides for unique ID allocations to users on a UPI-ID basis.

Major banks commenced issuing UPI-enabled apps to their customers in 2016. Since then, UPI has grown with remarkable speed and become the most popular payment method in India. By 2025, with over 19 billion transactions per month, India will become a global leader in real-time digital payments. UPI allowed people to transfer money instantly at any time, make payments to merchants, and manage multiple bank accounts from a single platform. It is not only simplified but also secured and democratized digital payments in India.  UPI is an inspiration to payment innovations across the globe and has altered India's path to becoming a cashless economy.

How Does UPI Work?

With UPI, a digital money transfer system, linking your bank account to a mobile app creates the facility of transferring money instantly at any time. Here is the working procedure in short steps:

Registration of a User: Download any UPI-enabled application (like PhonePe, Google Pay, Paytm) and link your current bank account. Create a unique UPI ID (like yourname@bank) and set a secure UPI PIN for authorization.

Initiating a Transaction: Enter the UPI ID or mobile number of the person you are sending money to, or scan the QR code of that person. Then, enter the amount you want to send.

Authentication: You pay the amount by providing your UPI PIN. This PIN protects your account and verifies that it is you indeed.

Processing the Payment: The app sends the request to the UPI system, which contacts your bank and the recipient's bank simultaneously. It checks whether there are sufficient balances and completes the transfer.

Instant Confirmation: Money is immediately transferred from the sender's account to the receiver's account, with notification to both confirming the transaction.

UPI allows you to make peer-to-peer transfers and merchant payments in real time without the need to share personal bank account details with other users. It is available at any hour of the day and works seamlessly over multiple banks and UPI apps, which makes digital payments easy and secure.

UPI Daily Transaction Limits

The government and banks set limits on UPI transactions for user safety. UPI has set daily limits to ensure safe and secure transactions for all users. These limits help protect your money and prevent fraud. If you reach the limit, you can transact again after the 24-hour cycle resets.

Limit Type Amount (in INR)
Daily transaction limit Usually ₹1,00,000 per day per user
Per transaction limit Around ₹10,000 to ₹1,00,000 (varies)
Max transactions/day Usually up to 20 transactions per day
Special higher limits Up to ₹5 lakh for education, health, and tax payments
