No, it wont. It will however allow the government an unprecedented level of monitoring over their citizens, as if CCTV wasnt enough. It will not stop terrorism, it will not stop illegal immigrants entering the country and then going into hiding.
Whats more worrying that the cards themselves are the ignorant (sorry, but that's the best word) people that don't give a monkeys about freedom and civil liberties and buy into the governement spiel of "itll stop the bad guys from blowing you up and the other lot from filling up the country".
Bull****, for gods sake, wake up, this is nothing more than a tool to track the people.
