A decade after its public launch, the Unified Payments Interface (UPI) has evolved from a new digital payment mechanism into one of the most important pillars of India’s digital economy. From small payments at neighbourhood shops to bank transfers and international remittances, UPI has transformed how millions of Indians transact.
Developed by the National Payments Corporation of India (NPCI), UPI was designed as an interoperable, simple and secure platform that could bring multiple banking services onto a single interface.
It was piloted in April 2016 with 21 member banks and opened to the public on August 25, 2016.
The scale of UPI’s expansion over the past decade has been remarkable.
Annual transaction volume increased from around 1.78 crore transactions in FY 2016-17 to more than 24,162 crore transactions in FY 2025-26 — nearly a 13,000-fold increase.
Transaction value rose from approximately ₹0.07 lakh crore to around ₹314 lakh crore during the same period.
The growth has continued in 2026. In July, UPI processed 2,365.8 crore transactions worth ₹29.87 lakh crore, with 741 banks live on the platform.
UPI has continuously expanded beyond basic bank-to-bank transfers.
The BHIM app, launched in December 2016, provided users with a dedicated interface for UPI payments. Dynamic QR payments followed in 2017, simplifying merchant transactions.
UPI 2.0, introduced in 2018, added features such as invoice notifications, signed intent and QR payments, recurring mandates and overdraft account linking.
In 2019, UPI became an alternative payment mechanism for retail investors participating in IPOs. The platform crossed one billion transactions in a single month in October 2019.
Subsequent innovations included UPI AutoPay, UPI 123PAY and UPI Lite, helping extend digital payments to more users and different transaction requirements.
One of UPI’s major strengths has been its ability to expand access.
UPI 123PAY enabled feature-phone users to make digital payments using options including interactive voice response, missed calls and proximity-based sound payments.
UPI Lite was introduced for smaller-value transactions, reducing the need to enter a PIN for every payment.
In 2024, UPI Circle added another dimension by allowing a primary user to authorise secondary users to make payments within predefined limits.
The RBI has also increased transaction limits for certain categories. The UPI tax-payment limit was raised from ₹1 lakh to ₹5 lakh per transaction, while the UPI 123PAY limit increased to ₹10,000. The UPI Lite wallet limit was raised to ₹5,000, with the per-transaction limit increased to ₹1,000.
The platform has increasingly become an entry point for other financial services.
Credit cards were integrated with UPI, while Credit Line on UPI, introduced in 2023, allowed eligible users to link pre-sanctioned bank credit lines as a funding source.
Authentication has also evolved, with on-device fingerprint and face-unlock options introduced in 2025, alongside Aadhaar-based face authentication for UPI PIN onboarding.
UPI’s reach is no longer limited to India.
The platform is now operational in 11 foreign countries, including Bhutan, Nepal, Singapore, the UAE, France, Sri Lanka, Mauritius, Qatar, Cambodia, Greece and the Maldives.
Recent developments have further expanded its international footprint. Cambodia joined the network in June 2026, while UPI-based cross-border remittances became operational between India and Greece.
On July 30, India and the Maldives also launched cross-border remittances between UPI and the Maldives’ instant payment system, Favara.
The expansion is helping create new channels for international payments and remittances.
UPI’s domestic scale has also given India a significant position in the global real-time payments ecosystem.
According to the Ministry of Finance, UPI accounted for approximately 49% of global real-time payment transaction volume in 2024. The figure was also highlighted by the International Monetary Fund in its June 2025 report on retail digital payments.
A major advantage of UPI is its interoperable architecture. Users can operate multiple bank accounts through a single application, while merchants can accept payments without requiring customers to use the same bank or payment service.
UPI’s first decade has been defined by rapid adoption, continuous innovation and international expansion.
What began with 21 banks has developed into an ecosystem involving hundreds of banks, millions of users and merchants, and an expanding range of financial services.
The next phase will likely focus on extending accessibility while maintaining security, interoperability and reliability.
For India, UPI’s journey is therefore more than the story of a payment platform. It demonstrates how digital public infrastructure built around interoperability can reshape everyday economic activity — from a small neighbourhood purchase to cross-border financial transactions.
