A new innovation introduced by scientists in Hong Kong has transformed the way pets are identified and protected. The city has introduced digital identity cards for pets, aimed at reuniting lost animals with their owners with increased efficiency.

It stores the vital details of the pet: name, breed, microchip number, vaccination records, and the owner’s contact information. If someone finds a lost pet, all they will have to do is tap on the card with a smartphone and instantly access that pet’s profile and contact the owner.
It presents an addition to the Hong Kong microchip and dog licensing system, making it easier and faster to identify and recover lost animals. The solution will not only enhance responsible pet ownership but also augment animal welfare via transparency and traceability.

PiD Is Not a Government-Approved Identity Card
Other pet owners go so far as to have photos or special designs on the cards, making them a kind of symbolic “HKID card” for their dogs and cats.
The PiD card is not an official government-issued ID, but the trend it represents one of integrating technology into daily pet care makes Hong Kong one of the first cities in the world to use smart tech for the sake of safety and connectedness for pets.
