Aadhaar, India’s unique identification system, has revolutionised how citizens access services, making processes more streamlined and transparent. Aadhaar is a 12-digit number issued by the Unique Identification Authority of India (UIDAI) on behalf of the Government of India to identify individuals. It can be used anywhere in India for identification and address verification. Within the Aadhaar ecosystem, several indicators such as Aadhaar Generated, Aadhaar Updated, e-KYC Done, and Authentication Done play crucial roles in determining the system’s efficiency and effectiveness. These indicators are vital not only for the functioning of Aadhaar but also for businesses and government agencies leveraging the system. Aadhaar is the largest biometric-based identification system in the world and a crucial component of the “Digital India” initiative. It can be verified online by a mobile OTP or a biometric utilising the Aadhaar authentication program. Once verified, Aadhaar can be used to validate income tax returns and identify recipients of subsidies, perks, and services. Additionally, it can be used to verify identity for employment, travel, and services like mobile SIM cards, bank accounts, and gas connections. Aadhaar can be downloaded from the UIDAI website or ordered by mail through India Post. In September 2018, the Supreme Court affirmed the Aadhaar system’s legitimacy, but it also declared that obtaining a cellphone number, bank account, or education does not require it. Privacy concerns have also caused several civil liberties organisations to oppose the project.
