How can I use an animal chip reader app to identify and track lost pets?

To use an animal chip reader app to identify and track lost pets, first download the app on your smartphone. Then, scan the microchip implanted in your pet using the app. The app will display the unique ID number associated with the chip. You can use this ID number to contact the microchip registry and retrieve the owner's contact information. Additionally, the app may have a feature to track the location of the pet using GPS technology.
