Microchips are a permanent way of identifying your pet. A very tiny computerized microchip is placed below the skin in a standardized area based on the type of animal. There is no working or moving part, so the chip can't stop working. The chip is encased in biocompatible material so there is no tissue rejection or reaction. The animals are also identified with a tag alerting to the fact that they have a microchip implant. If a pet gets lost, animal shelters, humane societies, and veterinarians have scanners that read the number on the chip. Lost animals are routinely scanned for a microchip. When the slim microchip is implanted, the owner is given the pet's unique ID number to register their pet with an international pet database.
