Is this one of those things like the GPS trackers they just sort of plant on your shit by trespassing, and if you find them they typically come to collect them because their cover is blown anyway and they are expensive?
Or is this one of those things that you need to like… actively do things with? From the pics it looks like an active-use device but idk shit about 2004 tech so… (I was an adult, but barely conscious of things)
