I put a very annoying jingle bell on my bag (or one of those jingly cat bells). The sound is distinctive, so if anyone moves my bag I hear it immediately. Just remember to attach it while in line at security and to tuck it in something soft afterwards so you don't annoy yourself

Something with multiple bells so the thief can't just cover one bell in his hand, or a bunch of http://www.westcoastpetsupply.com/2/...ls-Large-3-pk/.

I love the Hong Kong Airport's system that is so simple yet effective: Everything goes in the grey bins (except for larger carryons), purses, laptops, etc Your coins, watches and keys go in a smaller grey bin when you go through the metal detector and it is right next to you! So you get to keep your eyes on your stuff the entire time. They do not try and rush you through. Each large bin that holds your stuff has an alphabet assigned to it that corresponds to your lane and an individual bin number. You are handed a large white laminated sign that you hold along with your passport and boarding pass when you walk through. They do not let anyone touch a bin unless you have the correct big white sign.

If you get pulled aside for a secondary, they ask you to bring all your bins along with you to an area on the side that has a divider so no one can pick your pocket or your bin while your attention is on the agent.
