How does a microchip work? Is it like a GPS?

A microchip implant is an identifying integrated circuit placed under the skin of an animal. The microchip, about the size of a grain of rice, is administered similarly to a vaccine using a syringe, and uses passive RFID (Radio Frequency Identification) technology. Animal shelters, animal control officers and veterinarians routinely look for microchips to return lost pets quickly to their owners, avoiding expenses for housing, food, medical care and euthanasia. Many shelters place microchips in all adopted animals. Each Save This Life microchip number is searchable in popular search engines like Google. When someone finds a pet and searches the microchip number, they are able to privately contact the pet owner with a text message and an email. The pet owner receives a GPS map powered by Google Maps™ of where the person who found their pet is actually located. Microchips are not a GPS system, the online recovery system uses geo-tracking to locate the user when they send an alert.
