This is an interesting security control point for an airport. In addition to the usual human checker, there is a row of electronic checking gates.

They are *much* easier and quicker. All boarding passes printed at this airport include a ‘QR’ (scanning) code. Just walk up to a gate, hold your pass over the scanning window for a couple of seconds, and the gate opens…

… and you’re done.

More airports should do it this way.

I found myself observing this gate from the airline lounge that I have been sitting in to wait for my flight (which overlooks it).

One thing that was interesting to me, in terms of human psychology, is that at times a long line forms for the single human, leaving the electronic gates almost empty (as depicted in this photo).

At other times, the opposite becomes true, as people ‘start a movement’ via the electronic gates and the human then has nothing to do.
(all he *does* do is hand-scan the boarding pass and wave you through – just like the gates do).
