Keep your pet safe with an NFC & QR smart tag that stores their complete profile — name, breed, vet info, vaccinations, and your contact details. If your pet is ever lost, anyone who finds them can scan the tag and reach you instantly.
Store your pet's name, species, breed, color, weight, microchip ID, temperament, feeding instructions, and special needs — all on one scannable tag.
Keep vaccination dates and vet details on your pet's tag. Instantly shareable at boarding facilities, dog parks, or with pet sitters.
Activate lost mode and every scan sends you a real-time notification with the scanner's location. Coordinate directly with the finder through built-in messaging.
When someone finds your pet, they scan the tag and can message you directly — no phone numbers exchanged, no apps needed. You reply from your dashboard.

Yes. Share the Mrk with them and they can update your pet's details, add vaccination reminders and see where the tag has been scanned — useful when whoever had the dog at the park is the person who knows where it went missing. You choose per person whether they can edit or only view, and only you as the owner can offer a reward or unclaim the tag. SmartMrk+ lets you share each Mrk with more people — see the pricing page for the current numbers.
SmartMrk tags complement microchips. While microchips require a special scanner at a vet or shelter, a SmartMrk tag can be scanned by anyone with a smartphone. Together, they give your pet the best chance of being returned if lost.
SmartMrk pet tags work for dogs, cats, rabbits, birds, reptiles, and any pet that wears a collar or harness. The tag attaches to any standard collar ring.
