Pet tags are small identification tags attached to a pet's collar. They typically display important information such as the pet's name, the owner's contact number, and sometimes the pet's medical needs. These tags help ensure that lost pets can be quickly returned to their owners. In addition to basic identification, pet tags can also include microchip information or a QR code that links to a pet profile. This additional data can provide more details about the pet, such as their breed or vaccination history, making it easier for shelters and veterinarians to assist in case of emergencies.
