The GPS Technology

Ever got worried about losing your valuable items like wallet, keys car or even jewelry? Not again! Advancement of technology has enabled many companies like pod among others to develop trackers which can help you track your lost or stolen items through the use of Gps technology. What is Gps? Gps stands for global position system. However not all trackers are the same in functionality, through the use of one in an effective way can help us explore and understand how trackers works. There are several types of trackers which we will explore some of them and how they work and giving some advantages and disadvantages of using either of them. They include GPS tracker for wallet, WI-FI Bluetooth, and RFID.

Global positioning system- GPS is made up of a tag which is in the device to be secured. The tag works by communicating to satellite to ask for its location; several satellites will work together to find the place of the tag and send its location coordinates to a server, the server determines the position of the tag and transmits the location detail to you in your personal device.
GPS trackers have an advantage over the other trackers since they don’t involve tag and personal device these enable them to have a wide area of coverage, unlike others trackers. Tags in GPS tracker know its geographical location and will update the owner on the other end by broadcasting their location in real time and send the area to your personal device in case you lost your keys, wallets or a car.
However, GPS trackers have a disadvantage of their own since they use internet network and satellite they can be obstructed by tall building and bad weathers which may cut off the GPS signal. The tag also has to do all the bulk work alone this significantly, and these trackers need to be recharged after every two or three days.

RFID Stands for radio frequency identification. Its consist of two parts a reader and a tag. The reader uses radio wave to request information from the tag. It then interprets the signal it has received in return. RFID is made up of several tags; the work of the tag is to sit in the device quietly. Once the reader pings the tag. The tags send some signal to the reader (usually a unique identifies) which is stored in its cheap. Once the reader has received the unique code from processing it to determine the distance by calculating the delay in the return signal and confirming that it is the correct tag. This will allow you to play games of “hot and cold” and get the location of your lost gadget.
The simplicity of RFID makes it have some advantage. Since most information is processed by the reader, the tags are generally so small and use almost no energy some company believes that RFID battery can last up to ten years without need of being replaced.

All trackers have a tag which sends detail(unique code) to either the reader for RFID or server for GPS and help track the location of your lost gadget
