I decided to look into pet microchipping after reading an article about a modern detective who tracked down a married couple who committed fraud then left their home country to avoid the authorities. The detective succeeded where others failed in tracking them down after learning that their expensive dog was chipped. The dog had a unique medical condition requiring specific drugs. He tracked the pet initially via its medical requirements to a veterinary clinic in another county and then upon learning of the pets next visit – with a carer not the owners – they then accessed the animals microchip and were able to ascertain the owners new address leading to arrest.
How does the technology work?
Essentially a microchip the size of a grain of rice coated in a protective layer is injected under the skin of the animal at the back of the neck. Utilising passive radio-frequency identification (RFID) technology that conforms to international standards, the chip can be read by a hand-held scanner generating the power required by the chip to send back a unique 15-digit number. This number can then be fed into various pet databases to access the owner’s details. The start of the number usually indicates the country of origin followed by the microchip manufacturer.
Since the 6th of April 2016, all dogs in the UK must be microchipped, and from the 10th of June 2024 all cats in the UK must also be microchipped. Dogs and cats in the UK found without a chip can lead to a fine for the registered owner.
Those with access to the databases such as vets are not permitted to divulge information about the owner to anyone but the registered owner.
Scanners can be purchased freely as the microchips only store the unique ID number. The real data is stored in the pet databases and generally consist of the pet’s name, the owner’s name, address, and contact details.
Products such as automated dog and cat flaps can contain scanners that can read the microchips as the pet approaches so that only authorised pets may enter or leave the property.
