Comparison
QR tag vs microchip: what's the difference?
Microchips and QR tags cover different parts of pet identification, so they are usually used together.
| Criterion | QR tag | Microchip |
|---|---|---|
| How it is attached | Worn on the collar | Implanted under the skin by a vet |
| Who can read it | Anyone with a phone | Someone with a chip scanner (usually clinics, shelters) |
| Shows owner contact | Immediately on scan, as the owner allows | Shows only a chip number; needs a lookup in the registry where it was registered |
| Can fall off | Yes | No, it is permanent |
| Updating details | Edit in the app | Update in the chip registry |
| Medical procedure | No | Yes (implant) |
A microchip is permanent ID that cannot be lost; a QR tag lets a finder reach you right away without a scanner. Using both improves the chance of getting your pet back.
