This is just a one-way door to prevent people from walking the wrong way into the sterile area. Today, human beings have to sit there and watch people walk past all day -- what a boring and demeaning job!!! This is NOT a new security measure, it's the same old measure implemented in a different way. I think people are freaking out about the fact that the system detains you for a split second in the process. There are better solutions out there. For example, all of the train turnstiles in Japan are set to default-open. If they detect someone going through without paying, they close extremely rapidly as soon as you cross the front threshold. That should do the trick, although I guess it wouldn't stop someone from passing contraband across the gap.
