National ID card -Aadhaar card

The Supreme Court has ruled that Aadhaar card should be only linked with the PAN card, for filing income tax and for government subsidies( for the poor). Previously, the Aadhaar card was linked to all bank accounts and to all phones. Even to book tickets on trains or book hotels to stay; or getting admissions in schools or to write an entrance exam for higher studies. Now that is not so. But the fact Aadhaar card is used to note income tax etc is itself a big deal. Now the state can look at your income tax and this was not needed as PAN card itself was doing it. And soon getting driving license and for getting passports one would need Aadhaar. Again government can oversee the activities of the individual, more than it should.
For the poor people who were dependent on government subsidies, Aadhaar card would be useful, But internet fails much of rural areas and delays subsidies. At those times, subsidies cannot be delayed due to technical problems.People depended on MGNREGA for basic needs Aadhaar is useful. Previously, "family ration card" was enough to get subsidized necessities; it was not foolproof,.
After six months the Aadhaar data must be deleted(except in court cases) Is it deleted? And who will oversee that it is deleted.
The fact that data of Indian citizens is collected by taking image of individual's iris patterns, and fingerprints is itself very intrusive. Previously before the coming of Aadhaar, only criminals were fingerprinted and now everyone is reduced to a criminal. These are important issues which have been ignored in implementation of the Aadhaar scheme.
