Aadhaar
A Time repor from 2018 notes that India’s Aadhaar program is the "world’s largest biometric ID system". "When the program launched in 2009, India set out to achieve a world-first: giving every citizen a unique, biometrically-verifiable identification number. Those biometrics (iris scans and fingerprint records) would be linked to a person’s Aadhaar number, which would in turn be used in all interactions with the state—weeding out fraud, making taxation more efficient, and ultimately saving money, the government said...Today, 1.2 billion Indians—including over 99% of the adult population—are enrolled."

Writing in 2018 Siddharthya Roy explains: "The Aadhaar project was conceived and implemented by leading names in the Indian software industry. Nilekani for example, was the CEO of Indian IT and outsourcing giant Infosys. Most of the present members of the private companies that work with Aadhaar data are active members of the National Association of Software and Services Companies (NASSCOM) — India’s premier trade body for IT and outsourcing firms. The project also has big multinational corporations like Ernst and Young, Accenture, and the Safran Group working on it." [2]
