Speaking at the Heathrow launch Wednesday, immigration minister Liam Byrne said biometric screening will make it "much harder for people to get into the country illegally." He dismissed civil liberties concerns about the increasing collection and use of biometric data.
He said: "If you have got nothing to hide, what are you worried about? You are not only securing borders, but helping people save time when they are traveling. This kind of technology will be popular."
