This is good but I believe Amsterdam Schiphol airport does it as good, if not better. The conveyor belts at security are manned with staff to give advice or answer questions and curved so that 3 people can place their items on at a time (kinda like a blackjack table curved around the dealer). The millimetre wave scanner takes only a second and staff are prompt and courteous.

Perhaps most importantly though, they had 4 or 5 sets up and running at the same time. The overall process took me about 15 seconds of waiting and maybe 2 minutes once I got to the belt (I had a lot of stuff to unpack).
