QR collar tags: what they do that a microchip can't
4 min read
A microchip works only once the animal reaches a vet or shelter. A QR tag works at the moment a neighbour picks your dog up off the street, which is hours earlier.
How a QR tag works
The tag carries a printed code linking to your pet's online profile. A finder points their phone camera at it and lands on a page with your pet's photo, name, any medical needs, and a way to contact you.
No app install, no account, no scanner. That low friction is why finders actually use them.
What to put on the profile
Pet name, a current photo, temperament ('friendly, will follow food'), any medication or allergies, and your preferred contact route. Keep your home address off it.
On Pet Social the QR tag opens a private in-app chat, so a finder can reach you instantly while your phone number stays private.
Keeping it usable
Print or engrave on a durable tag, keep it flat rather than curled, and replace it when the surface scratches. Test the scan yourself every few months.
Run a QR tag alongside the chip and a plain engraved tag — three layers, each covering the others' blind spots.
Frequently asked questions
Do QR tags need a subscription?
Pet Social's printable tag is free with your pet's profile. Some commercial tags charge annually — check before you buy.
What if the finder has no signal?
Keep an engraved tag as backup. A phone number or a name plus suburb still works offline.
