Tracking Devices
Up until recently, I assumed that tracking devices were the stuff of fantasy. After all, I was raised on cold war era movies like most of my generation was. The tracking device was something that James Bond would use to locate the villain. It seemed like such a high-tech apparatus at the time. In a time when computers were large and wimpy, spy devices were practically microscopic and extremely powerful. Obviously, it was hard to believe that such a thing was possible in my lifetime.
Nevertheless, nowadays GPS tracking devices are commonplace. There are many different ways to design a tracking device, and the different ones on the market all serve different purposes.
