The project is called Aadhaar, and on it's surface it doesn't seem to be that bad, its a government ID that contains biometric and demographic data and doesn't seem to contain much more than what is requested of people at the US boarder, or what is contained on most national ID cards in jurisdictions where those exist, and at least the Aadhaar is voluntary, that is the government cannot deny service if someone chooses not to possess an Aadhaar ID. Reading the Wikipedia article also gives hope that the project isn't as bad as it might be.

"On 24 March 2014, the Supreme Court restrained the central government and the UIDAI from sharing data with any third party or agency, whether government or private, without the consent of the Aadhaar-holder in writing." [0]

"On 26 September 2018, the Supreme Court ruled that Section 57 of the Aadhaar Act was unconstitutional, meaning that private entities cannot compel their customers to provide their Aadhaar number as a condition of service to verify their identity, specifically citing requiring it for bank accounts, school admissions, and mobile phone service as examples of unlawful use cases" [0]

I still wouldn't want to have this kind of a system pushed on me, but then I would prefer if the ID chip was removed from my passport...
