In recent years, the Unified Payments Interface (UPI) has emerged as a game-changer in the world of fintech. UPI is a real-time mobile payment system in India that enables users to transfer funds instantly between different bank accounts. It has not only transformed the way people transact but has also paved the way for the internationalization of digital payments. In this blog, we will delve into the details of UPI, its impact on the fintech industry, the top players in the field, and the global expansion of UPI.

Understanding UPI


Unified Payments Interface (UPI) was launched by the National Payments Corporation of India (NPCI) in 2016. It is a payment infrastructure that allows individuals to link multiple bank accounts and make payments using a single mobile app. UPI operates on a safe and secure platform, providing users with a seamless and convenient payment experience.

UPI Specifications and Transaction Limits

UPI is based on the concept of a virtual payment address (VPA), which is a unique identifier that can be linked to any bank account. A VPA can be in the form of a mobile number, an email address, or a custom name, such as john@bank. To make a UPI payment, one only needs to enter the VPA of the recipient, without having to share any bank details or card information.

UPI also supports various payment modes, such as scanning a QR code, entering a UPI ID, or using other options provided by different UPI apps. UPI apps are the applications that facilitate UPI transactions, such as PhonePe, Google Pay, Paytm, Amazon Pay, and many others. These apps are interoperable, meaning that one can use any UPI app to pay for any other UPI app.

The UPI transaction limit refers to the maximum amount of money that can be transferred in a single UPI transaction. As of now, the UPI transaction limit is set at Rs. 1 lakh per transaction for most UPI apps. However, some banks and UPI apps may have different transaction limits.

The UPI transaction limit per day is also determined by NPCI and the banks. The NPCI has set a limit of 20 transactions per day for normal UPI transactions, and a limit of Rs. 5 lakhs per day for peer-to-merchant transactions (such as bill payments and merchant transactions). However, these limits may vary depending on the bank and the UPI app.

Revolutionizing Fintech


Seamless Transactions

UPI has eliminated the need for traditional methods like cash or cards, offering a more convenient and secure mode of payment. Users can make payments with just a few taps on their smartphones, reducing the hassle associated with traditional banking.

Financial Inclusion

One of UPI’s key strengths lies in its ability to bring financial services to the masses. Even individuals without a traditional bank account can access digital transactions through UPI, fostering financial inclusion and bridging the gap between urban and rural areas.


UPI operates on an open architecture, allowing interoperability between different banks and financial institutions. This has created a level playing field, encouraging healthy competition among players in the fintech space.
