the strange thing is apart from some military tracker most of them have a manufacturer/type scribed on them
chance of you having one is virtually zero
(although i say that, but we crash cars on purpose from time to time for the blackbox development, and one of the cars we got from the scrap yard had one of our own blackbox/tracker already in it!...)
as for tracker only answering to a ping, well, they might check once a day, but can't be listening all the time, it would take to much power and would need to be connected to a car battery. my 2004 bmw 1 series is like that, the tracker is radio, activating on a broadcast, then emitting a ping, not gps/gsm lol a bit like the animal tags feels so prehistoric now!
someone tried to scan the barcode, and i bet it is the same as the number displayed, which returns nothing when googling it
if you decide to break it open, be very careful. if it has a lithium battery inside, it could blow in your face/start a fire. (see e-cig explosions)
if we don't manage to find what it is, maybe a vet/dentist might be kind enough to x-ray it for a small fee and curiosity to see what's inside
<troll>if you do nothing illegal why does it bother you </troll> btw, leave the toilet door open while you're in there lol
