Microchip vs QR pet tag: what's the difference?

A microchip and a QR pet tag both help reunite lost pets with their owners — but they do it in completely different ways, and they're read by different people in different situations. This page lays out what each one actually does, where each one shines, and why most owners end up using both.

What a microchip does

  • It is a small RFID chip implanted under the skin by a veterinarian. Once placed, it stays for the life of the pet.
  • It is read by a specialized RFID scanner. A regular phone cannot read it. Vets, shelters, and animal-control officers carry these scanners.
  • The chip itself stores an ID number. The owner's contact information lives in a separate microchip registry that the owner has to keep up to date.
  • It is read in a clinical or shelter setting — by someone whose job includes scanning. It is not used by a member of the public who finds your pet on the street.
  • In many jurisdictions, microchipping is required by law for certain pets. It is the legal-and-clinical backstop layer of pet identification.

What a QR pet tag does

  • It is a visible tag worn on the collar with a QR code on it. A finder can see it the moment they approach your pet.
  • It is read by any modern smartphone camera. No app, no specialized scanner, no training needed.
  • It links to a digital pet profile the owner controls. The owner edits the profile any time without buying a new tag.
  • It is privacy-controlled. The owner chooses which fields are visible to a finder; defaults are designed to share just enough.
  • It has no battery, no GPS, and no transmitter. The tag does nothing on its own — it works only when a person scans it.

Why most owners benefit from both

A microchip and a QR pet tag are not substitutes; they're layers. They're read by different people in different moments, and each one fills a gap the other has.

  • A regular person who finds your pet on the street can't read a microchip — but they can scan a QR pet tag.
  • If your pet ends up at a shelter without a collar, a microchip is what reunites you — the QR tag is gone.
  • The QR tag is editable, public-facing, and immediate. The microchip is permanent, registry-backed, and clinical.
  • Together, they cover the two most common pet-found scenarios: a stranger reaches you fast, or a clinic reaches you eventually.

Common questions

If my pet has a microchip, do I still need a QR pet tag?

A microchip helps when a vet or shelter is involved. A QR pet tag helps when a regular person finds your pet first — which is often what happens. Most owners use both.

Can a stranger read a microchip with their phone?

No. Microchips use RFID and require a specialized scanner. Phones can't read them.

Is a QR pet tag a replacement for a microchip?

No. A QR pet tag is a finder-side tool worn on the collar. A microchip is a permanent backstop under the skin. They do different jobs.

What happens if my pet loses the collar?

Collars come off. That's exactly why a microchip backstop matters. The two tools cover each other's gaps.

Do I have to update both if I move?

Yes. Update your microchip registry through the registry's website, and update your Driyu profile from your account. The QR tag itself doesn't need to be replaced — only the profile content.

Can I see my pet's location from a QR pet tag?

No. There is no GPS, no battery, and no transmitter in a QR pet tag. The tag is a finder tool, not a tracking device.
