Wired:

Instead of having a human poke around in your bag, the machine scans it for a variety of threats in just a few seconds.

You hold your ticket up to the machine, and it assigns you a pod. Close the door and walk around to the other side. In the time it takes you to get over there, the machine scans the bag for a range of threats.

There are some obvious issues with the embedded company video but those are easily remedied. It would be great to see these kinds of systems in place rather than the awful TSA procedures many of us have to go through now.
