SMART TAG microchips help you locate your lost animals by using small tracking implants. A veterinarian or trained vet tech simply injects a microchip beneath the surface of your pet's skin between the shoulder blades. No anesthetic is required. The process is similar to a routine shot, takes only seconds, and your pet will not react any more than to any vaccination. The microchip has an anti-migration coating and has no internal energy source. The microchip is read by passing a microchip scanner over the pet's shoulder blades. Each of the 25 units contain a 15 gauge, sterile, one-time-use syringe applicator containing pre-loaded microchip with matching metal SMART TAG ID tag and 10 labels in sterile packaging. There are no registration fees, annual fees, update fees or transfer fees. Register your pet by creating your profile and add up to 2 emergency contact phone numbers, breed, size, color, photos, and vet Information. Unlimited free updates to your pet/owner profile. If your registered pet is reported as lost, SMART TAG instantly broadcasts a nationwide lost pet amber alert to all the shelter and rescue organizations in a 50-mile radius of the pet's last known location. We also provide 24/7, US-Based Live support, Instant Lost Pet Posters and more.
