From a safety device for the elderly to a roadside assistance solution, and everywhere in between, the only limit to these devices is your imagination! These GPS Devices provide a unique platform for a variety of interest groups and purposes; from Kid Tracking, lone-worker protection, elderly tracking, or personal safety. You can request the position of the device and show it on a computer screen or mobile tracker. You can automate tracking and location based on various conditions: create a geo fence around a person or location by enabling an alarm on a barrier crossing or barrier entry. http://www.gpsnanny.com/rs/reginao/products.html
