My favorite so far was the baggage scanning/check system at VTE(Vientiane, Laos). It's surprisingly modern. Bags go through a giant X-Ray machine, not unlike the bomb-sniffing ones that were SUPPOSED to be in all US airports last fall,
and then at the other end, the bag hits a push-plate which triggers this automatic strapper to zip plastic strapping around your bag and seal it right in front of you.

Then you pick your bag up, walk it over to the check-in desk, they look at it, see that it's sealed and just toss it on the belt. When I got to BKK, my bag was still sealed and
stayed so until I got to my hotel.

WAY better than the TSA.
