One tap and every lost dog finds its way home.

DogTag is an NFC chip for the collar that opens your pet's profile on any phone — no app to install — and emails you a Google Maps link the moment someone shares where your pet is.

Works on iPhone XS+ and virtually all Android phones · Finders choose what to share — nothing is ever captured without their knowledge.

How DogTag works

🏷️
STEP 1

The chip holds a link — nothing else

Each collar chip is encoded with one short URL like https://www.nfcpet.net/t/AB12CD34. No names, phone numbers or emails are stored on the tag itself: anyone can read an NFC chip's raw contents with a free app, so DogTag keeps personal data off the chip and behind the web page instead.

📱
STEP 2

A finder taps — any phone, no app

iPhone (XS and newer) and Android both read the chip natively and open the pet's profile: photo, name, medical notes, and big call / text buttons for the owner.

STEP 3

The owner gets an email with a map

If the finder taps “Send report”, the pet's GPS position, an optional photo and a message are emailed instantly to the responsible address registered for that chip. The phone shows its normal permission prompt first — sharing is always the finder's choice.

🔒 Why nothing happens “silently” — by design

Customers sometimes ask whether a tag can secretly photograph the person who scans it or quietly pull their location. It can't — and any product claiming it does would be lying or breaking the law:

  • NFC chips are passive storage — a scan opens a link; it can't run code on the phone.
  • Android 9+ blocks camera access for background apps and Android 12+ lights an indicator whenever any camera is used; iOS is even stricter. Browsers require a visible permission prompt for camera and location.
  • Covertly capturing someone's photo or location is non-consensual surveillance — unlawful under the CFAA (US), the Computer Misuse Act (UK) and equivalents worldwide.

DogTag's consent-first flow is what real pet-recovery platforms do — and it converts better too: finders help when the experience is transparent.

Built for NFC Connection's workflow

  • ✅ Bulk-friendly: register tags, then write each URL to a chip with any NFC writer (NFC Tools, MacroDroid — full walkthrough in the NFC guide).
  • ✅ Owner dashboard: magic-link sign-in — every finder report (map, photo, message), inline editing, test emails, chip URL copy.
  • ✅ Updateable: the chip only stores a link, so details can change any time without re-encoding collars.
  • ✅ Email delivery: PHP mail() out of the box on this host, or Resend for higher volume.
