GPS technology (Global Positioning System) is being increasingly used, in fact, the vast majority of smart phones come with a built in GPS which allows users to locate addresses in applications like Google Maps.
A device smaller than a cell phone or pager is capable of receiving information in real time via satellite, it can be used with children or people who need especial attention, such as Alzheimer’s patients. This device was introduced by the Location World company in Ecuador, which specializes in tracking systems.
Alvaro Merchan, World Location company official, explained that the locator technology allows users to create virtual fences that send an alert when the device enters or leaves the previously determined area. This alert is not sent to the locator’s direct user, but to the person who contracted the service. Users also have the opportunity to see the history of the routes taken by the carrier of the device.
To access this system from a cell phone, a service of mobile operators in the country must be hired.
