India has emerged as a global pioneer in building digital public infrastructure that empowers citizens, boosts transparency, and drives economic growth.
The suite of tools, collectively known as India Stack, is transforming governance and public service delivery while offering a model for other countries.
At the core of this transformation lies Aadhaar, the world’s largest biometric digital identity system, which provides over 1.38 billion residents with a unique ID.
Aadhaar serves as the foundation for accessing services ranging from banking to healthcare.
The Unified Payments Interface (UPI), built on this identity layer, has revolutionised digital payments by enabling seamless, low-cost money transfers.
Alongside, platforms like DigiLocker enable secure digital storage of official documents, and CoWIN showcased how India Stack can scale for public health efforts, managing one of the world’s largest vaccination drives.
India Stack’s success is rooted in its principles of openness, scalability, and interoperability.
Open APIs allow private developers to innovate freely, leading to a vibrant fintech and digital services ecosystem.
Modular architecture ensures the system handles massive volumes, while interoperability avoids siloed data and enables unified experiences across services.
India’s digital infrastructure supports enormous volumes.
UPI now processes over 14 billion transactions per month, valued at around $2.4 trillion annually.
Experts forecast that by 2027, UPI could handle 1 billion transactions daily, covering 90% of digital retail payments in India.
Systems like the Ayushman Bharat Digital Mission connect thousands of health facilities, while the Direct Benefit Transfer (DBT) system, powered by Aadhaar, has saved the government nearly $24 billion by removing fraudulent beneficiaries from welfare schemes.
India has focused on inclusive digital access across its diverse population. DigiLocker, used by over 270 million people, supports multiple languages.
The CoWIN portal, available in regional languages, ensured broad accessibility during the COVID-19 pandemic.
Offline verification for Aadhaar, rural connectivity initiatives like BharatNet, and over 500,000 Common Service Centres (CSCs) have extended digital access and training to rural and remote areas.
As digital systems expand, India has prioritised data protection. The Digital Personal Data Protection Act enforces strict regulations, with penalties up to ₹250 crore ($30 million) for violations.
Aadhaar uses encryption and biometric hashing to protect user data, and systems require explicit consent for data sharing.
Public grievance mechanisms, such as UIDAI’s Aadhaar portal, allow citizens to resolve issues quickly, enhancing trust.
