You've seen them in movies: tracking devices so small they can be put inside a tooth or embedded under the skin. In reality, tracking devices--for the general public at least--are not that tiny, but they can be pretty diminutive.
Lightning GPS introduced a small tracking device on Wednesday called the Spark Nano. Of course, you'll need to take the "Nano" notion with a big grain of salt. The device is actually about the size of a 9-Volt battery--you know, the big one that's used in a smoke detector. The Spark Nano is, however, rugged and waterproof.
Its size means you can easily install the Spark Nano on the object that needs tracking; you can clip it on a person's belt or put it inside your kids' backpack to keep tab of their whereabouts. The Spark Nano also features a panic button that the wearer can use to alert people if he or she is in danger. The alert would show exactly where the person wearing the tracking device was located.
For people at home, the Spark Nano can be tracked in real time via a Web site, either with a computer or via a smartphone. It can also be set to periodically send e-mails and text messages indicating the location of the tracked object.
The Spark Nano has a built-in rechargeable battery that can power the device for five continuous days with a full charge. It sports "Safety Zone" Technology that alerts you when the tracked object arrives at a target or exits a predefined area.
The new GPS tracking device is available now and costs $299.95. It also requires a service plan that starts at another $45 a month.
