I am wondering if anyone has tried the location tracking device "LugLoc." You stick it in your luggage and it uses GSM towers to triangulate its location. There is another device called "Trakdot." I found one post from 2 years ago. Trakdot takes a slightly different approach but similar idea.
I understand that the best this could do would be able to tell me if the bag is in the airport I am at or... at some other airport... or somewhere else. It won't pinpoint the exact location down to a few meters.
Anyone used a luggage tracker? Or thoughts on the idea?
