The microchip is a tiny computer chip, about the size of a grain of rice, programmed with an identification number. Once an animal is injected with a chip, it can be identified throughout its life. A special scanner is used to send a radio signal to the chip to read the identification number. The number is displayed on the scanner, and the person reading the scanner can contact a national registry to find out who the pet belongs to.
The microchips are enclosed in biocompatible glass and small enough to fit into a hypodermic needle, making injecting them as easy as giving a vaccine.
Microchips are permanent and can’t be lost, altered, or destroyed. Pet owners have been reunited with chipped pets that have been missing for years or that have traveled thousands of miles.
After your pet is chipped, you will be given information about how to contact the national registry to update your information. Remember to do this whenever you change your address or phone number.
