There is a saying that “it takes a thief to catch a thief”. This is because to know the modus operandi of a presumptive thief is to know when, where and how that person operates. What better way than to put a ‘tag’ that will follow every movement of that person to gather evidence in order to implicate that person. Hiding a global positioning system (GPS) on a person’s vehicle is one means of collecting information with a view to later prosecution of the driver of the vehicle where a criminal act is committed.

In the aftermath of the terrorist attacks on New York and Washington, finding people and bodies in the rubble was of utmost importance. This task was directed at finding location bearing devices incorporated in commonplace instruments such as mobile phones, personal digital assistants (PDAs) and electronic pagers. By polling these devices electronically using a system of triangulation points it was thought that persons and bodies could be found. Polling is simply sending electronic impulses to receivers to ascertain where these devices are located. However, and sadly, such devices have a limited range and may have no effect if buried in more than a meter of rubble. Also, some such devices incorporate global positioning systems (GPS) and these require access to the sky and to the constellation of satellites orbiting the Earth. Even the sniffer dogs gave up this mammoth task.
