It's one of the most common questions new pet parents ask: if my pet is microchipped, do I still need a tag? The short answer is yes — because they solve two different problems.
What a microchip does
A microchip is a permanent, implanted ID about the size of a grain of rice. It's excellent for proving ownership and is read by vets and shelters using a special scanner. But it has limits: it can only be read by someone with a scanner, the registry details are often out of date, and a member of the public who finds your pet can't access it at all.
What an NFC tag does
An NFC tag lives on the collar where everyone can see it. Anyone with a smartphone — which is almost everyone — can tap it and reach you immediately. It's the difference between a system designed for institutions and one designed for the neighbour who finds your dog two streets away.
Side by side
- Who can read it: Microchip — vets and shelters only. NFC tag — anyone with a phone.
- Speed: Microchip — requires a visit and a scan. NFC tag — instant tap-to-call.
- Staying current: Microchip — depends on registry updates. NFC tag — you edit your profile anytime.
- Visibility: Microchip — hidden. NFC tag — visible deterrent and invitation to help.
The smart answer: use both
A microchip is your permanent backup and proof of ownership. An NFC tag is your first line of defence — the fast, public, always-current way for anyone to bring your pet home. Together they cover every scenario. A Thingness tag complements your microchip rather than replacing it.
