In the last two decades, India has quietly engineered one of the most transformative digital revolutions in the world - through the creation of its Digital Public Infrastructure (DPI), anchored by Aadhaar and Unified Payments Interface (UPI). This milestone has redefined how citizens interact with the state, access services, and participate in the economy.
Launched in 2009, Aadhaar is the world’s largest biometric ID system, assigning a unique 12-digit identity number to over 1.3 billion residents. It uses fingerprint and iris scans to verify identity, enabling secure and inclusive access to government services. Aadhaar became the backbone of India’s digital identity framework, facilitating direct benefit transfers, mobile SIM verification, and financial inclusion.
Building on this foundation, India introduced UPI in 2016 - a real-time payment system developed by the National Payments Corporation of India (NPCI). UPI allows users to instantly transfer money between bank accounts using mobile phones, without needing account numbers or IFSC codes. What makes UPI revolutionary is its interoperability across banks and apps, and its simplicity: a few taps on a smartphone can complete a transaction.
Together, Aadhaar and UPI have created a seamless, scalable, and secure digital ecosystem. This DPI has enabled India to leapfrog traditional infrastructure challenges and bring millions into the formal economy. For example, during the COVID-19 pandemic, the government used Aadhaar-linked bank accounts to deliver emergency cash transfers to vulnerable populations - quickly and efficiently.
The impact of UPI has been staggering. In 2024 alone, UPI processed over 100 billion transactions, with a total value exceeding ₹150 trillion. It has become the preferred mode of payment for everything from street vendors to e-commerce giants. India’s digital payment volume now surpasses that of the United States and China, making it a global leader in fintech innovation.
This DPI model has also inspired other nations. Countries like Indonesia, Morocco, and the Philippines are exploring similar frameworks, and India is actively sharing its expertise through initiatives like the India Stack and Modular Open Source Identity Platform (MOSIP).
What sets India’s DPI apart is its public-good orientation. Unlike private platforms, Aadhaar and UPI are open, inclusive, and designed to serve every citizen. They have democratized access to services, reduced corruption, and empowered individuals - especially in rural and underserved areas.
India’s digital infrastructure revolution is not just a technological achievement; it is a social and economic transformation. It reflects the country’s ability to innovate at scale, solve complex problems, and build systems that are both robust and equitable.
As India continues to expand its DPI with initiatives like ONDC (Open Network for Digital Commerce) and DigiLocker, the Aadhaar-UPI milestone stands as a testament to what visionary policy, technological ingenuity, and inclusive design can achieve.
India didn’t just digitize - it reimagined the digital future. And in doing so, it gave the world a blueprint for inclusive digital development.
