QR engraved on a pet medallion. Password-locked while the pet's home; one tap exposes owner contacts, and the scan itself alerts the owner by email and webhook.
Owners flip the QR between a private placeholder and a public 'lost pet' page from the EQR panel. A scan sends an alert email to the address on the code and fires a signed webhook carrying the time and the country the tag was scanned from — wire that webhook into your own SMS gateway if you want a text. No tracker hardware, no battery to charge.
Free tier includes 1 standard QR code. Upgrade to the paid Eternal tier for blockchain permanence and the recovery key.
