In that particular case, that is so, but it would not necessarily require an ID card to make the link with a mobile phone. In other words, there are other ways of achieving that.
About a third of terrorists use multiple forms of identity, so the Government have claimed that ID cards would help in tracking down terrorists. Once again, that is a false and a dangerous argument. Nothing in what the Government have suggested would prevent international terrorists from coming into this country with false documents—what are known as seed documents—and registering under a different name for an ID card with their biometrics on it. Indeed, that highlights the danger of ID cards providing a false sense of security. Unless an international system is put in place, and countries such as Afghanistan and Saudi Arabia all signed up to the same form of biometrics, there is no reason to assume that individuals could be stopped from moving around with different identities in different countries.
