A microchip is a Radio Frequency Identification Device (RFID) device that can transmit stored information. A microchip is about the size of a grain of rice and is injected under your pet’s skin. It can be done during a normal consultation or at the same time as a surgical procedure such as speying or castration. The embedded microchip contains a code that is unique to your pet and is the most effective form of permanent identification. This code is placed onto a national computer database, so it is particularly useful in the return of lost pets. Microchips can also assist where the ownership of an animal is in dispute. In some states of Australia microchipping of pets is now compulsory.
If a pet is ever lost and handed in at a veterinary clinic or animal shelter a microchip scanner is passed over the animal to reveal the unique code. The vet or animal shelter can then refer to the database to identify the name, address and phone number of the owner, so they can be reunited.
