You just spilled the beans. Now we have to kill you.
Why not just a transmitter in a wristwatch??? The nicer looking the watch, the better.... Even if the wearer does get it taken from him, the bad guys arent just going to throw a nice looking watch on the side of the road... they'll wear it... keep it as a trophy... Keep it till they can sell it... meanwhile, its telling the goodguys where the snakepit is...
Motorola has introduced a new miniature Global Positioning System (GPS) chip called the FS Oncore module that is not only full featured, but small enough to fit just about anywhere. At only 200 square millimeters it is designed to enhance virtually any mobile device.
Power consumption is also a respectable 70 mW, and includes the ability to go into a standby mode. With support for autonomous and assisted GPS modes it is not only well suited to cellphones, but could provide positioning information for a PDA or assist with asset tracking. There are many other applications that could greatly benefit from GPS in such a small package, but at the same time this brings up other concerns.
It is handy to have GPS capabilities on every mobile device, but it can also be used to provide information about everywhere we go, kind of an electronic leash. You have to wonder how long it will be before someone decides it is a good idea to implant tiny GPS devices in humans. I don't mean to sound like a conspiracy theorist, but along with all of the great applications a product like this can provide we need to be certain it is used properly.
