Great idea these tracking mechanisms, but I can’t help but get all James Bond-ish about it... if this tag produces a signal, then it can be tracked by anybody. I don’t see how this stops a thief... eventually hackers will make a device that can search for signals on the same frequency and then know right where the tracking tag is and pull it, and throw it in the river.
I’m not a pessimist, just being realistic here... not sure how these items protect anyone from having anything of value from being stolen.
For now, i know how much i hate wearing my phone when i go out for a run, so i can see myself wearing one of these tags so if i don’t make it home, someone could actually come looking for me and find me.
Realistic sort of implies keeping things real; which you are far from doing as you don't understand the technology at all.
It's not a cellular device with a GPS, so they don't work as you think in the case were you would wear one; and you have some sort of fear of "hackers" listening to signals, where the important thing is rather lack of signal (or signal in combination with movement unrelated to the owner's movement), which would alert the owner of an initiated theft (so you can run to your things, yell thief, or follow the thief while on the phone with the police).
