From ABC News:
In one high-tech thriller after another, the hero attaches a tiny tracking device on the villain and follows him as blinking dot on a computer screen.
In real life, this kind of technology would be great for tracking pets or kids, even packages or luggage — anything that tends to wander.
But it doesn’t really exist.
There are GPS devices, of course, but strap a half-pound GPS collar to a dog and you’ll realize it’s far from “Mission Impossible.” GPS-enabled cell phones are becoming more common, but they have problems, like accuracy indoors, and they aren’t cheap.
A Utah company, S5 Wireless, is looking to bring reality closer to the movies, with small, cheap chips that can be powered by a single battery for up two years and tracked indoors and outside, over long distances.
