Stores the finder-page link
The owner app writes the activated profile link to the passive NFC tag. There is no battery, charging, or Bluetooth pairing.
How PetDentify works
PetDentify is a passive NFC pet ID tag. A finder taps it with a compatible phone, opens your pet’s current finder page, and chooses the owner or an enabled Safety Circle contact to call.
The mechanism, without the mystery
It does not store a live location or broadcast a signal. It gives a compatible phone a link to the finder page tied to your pet.
The owner app writes the activated profile link to the passive NFC tag. There is no battery, charging, or Bluetooth pairing.
An unlocked NFC-enabled phone reads the tag at close range. The finder needs a browser and internet connection, but no PetDentify app.
The finder sees the pet’s name and photo, a Call owner action, and any enabled Safety Circle contacts with their own Call actions. A tap does not automatically call or notify anyone.
Why the page stays useful: saved profile changes appear on the dynamic finder page without rewriting the physical tag.
For the person who finds your pet
The finder experience is intentionally short because the person helping may be stressed, outside, or in a hurry.
Hold an unlocked NFC-enabled phone near the tag and open the notification.
Use the name and photo on the finder page to make sure the profile matches the pet.
Call the owner first or choose an enabled Safety Circle backup contact if the owner is unavailable.
The physical tag does not print a phone number, but anyone with the finder-page link can see the pet information and contact actions the owner enables. Add only consenting Safety Circle contacts and keep those choices current.
For pet owners
The owner app creates the profile and writes its link to the tag. Finders use the public browser page—not the owner app.
Add the pet’s name and a clear photo, then review the profile information you want available.
Add consenting Safety Circle contacts only if you want the finder to have backup people to call.
Choose Write to Tag and hold the NFC tag near the phone until the app reports success.
Open the page from the tag, confirm the name, photo, and call choices, then attach the tag securely to the collar or harness.
What it needs—and what it is not
PetDentify creates a direct finder-to-contact path. It does not guarantee recovery and should complement—not replace—a registered microchip.
Most modern iOS and Android phones support NFC. The phone must be unlocked, and NFC may need to be enabled.
NFC opens the link; a browser and internet connection load the current finder-page information.
The passive tag has no battery and does not broadcast or provide live location tracking.
A shelter or veterinarian can scan a registered microchip when a finder’s phone cannot read or load the tag.
