Smart trackers consist of a tracking mechanism which is clubbed with a GPS transmitter that can be latched onto the end product. The smart tracker is connected to a parent device via wireless. The parent device is configured in such a way that the tracker sends real-time location alerts to this parent device and the parent device can be used to decipher the signal and detect the real-time location.
It can be used to track vehicles by fixing it on the outer part of the vehicle. A minimal version of the smart tracker can also be used to track the whereabouts of pet dogs and other animals by mounting it onto the collars or other wearable merchandise. These may also come in the form of small keychains which can be easily carried around or affixed to luggage to help keep a track of it as well. Smart wallets are another addition to this stream of smart trackers which automate a trigger once the wallet is reported lost and send the current location to the parent device, which helps in serving as the information to track down the lost wallet. This helps in enhancing the security by using tracking technology.
