It must be made clear that a microchip itself does not track your pet. Microchips are primarily used for identification purposes, but with PetScanner, when scanning a microchip, the device allows a pet to be located using the GPS position of the phone that is connected to the device.11 Oct 2018
What does a dog microchip tell you?
Each microchip contains a registration number and the phone number of the registry for the particular brand of chip. A handheld scanner reads the radio frequency of the chip and displays this information. An animal shelter or vet clinic that finds your pet can contact the registry to get your name and phone number.
