I'd like a passport holder that sets off an alarm on my phone eveytime its more than 2 meters away. You'd only have it active when you are travelling. Might help relieve some of the paranoia I have about loosing it. I Say passport holder because I'm not sure if you could physically affix if to the passport without upsetting border control.
