Dear FN, If you are a law abiding citizen and you pay income tax / file a tax return (required now the moment your income crosses 5 lakhs), then you have to compulsorily have a PAN card. PAN is linked to Aadhar Card. Banks/ insurance companies insist on Aadhar linkage. So there you go, the Government has you by your short and curlies.
Even if you don't come in the tax bracket, you are probably drawing subsidised rations so Aadhar is necessary. Even for students and teachers Aadhar is compulsory. BIG BROTHER IS WATCHING YOU! Tony de Sa
