A microchip is a very small electronic device, about the same size as a grain of rice, that is implanted under your pet’s skin.
Every chip has a unique 15-digit number stored within it, on circuitry this is encased in a protective shell made of glass or biopolymer. This casing helps to prevent the microchip from causing a reaction or moving around, which can make it difficult to read.
Microchips are designed to last the lifetime of your pet. The microchip is read from close range using a special scanner.
