Centre's flagship Aadhaar card scheme is Constitutionally valid, the Supreme Court said on Wednesday. A 5-judge Constitution bench headed by Chief Justice Dipak Misra banned a number of things that Aadhaar card had become necessary for. SC says nothing in Aadhaar Act violates right to privacy of individual. SC said benefits under the Aadhaar scheme should be in the form of welfare schemes and it cannot be made compulsory for services such as bank accounts, mobile connections or school admissions. Aadhaar card number, which is linked to a person's face, iris and finger prints, is used to help plug theft and leakages in the country's massive welfare programme.
