QR engraved on a pet medallion. Password-locked while the pet's home; one tap exposes owner contacts and pings the owner with a geo-scan SMS the moment somebody finds them.
Owners flip the QR between a private placeholder and a public 'lost pet' page from the EQR panel. Scans fire a webhook with rough geolocation so the owner gets an SMS the moment a stranger picks up their dog. No tracker hardware, no battery to charge.
Free tier includes 1 permanent QR and the recovery key — upgrade the slot with the exact modules this case uses whenever you need them.
