In brief
- Identification by microchip or tattoo is mandatory in France: the medallion does not replace it.
- A microchip can only be read with a scanner (vet, pound).
- An engraved tag can be read by eye, but cannot be changed.
- The QR medallion can be read with any smartphone and updated at any time.
Microchip, engraved tag, connected medallion: they are often confused, yet they do not serve the same purpose at the same moment, or for the same people.

The microchip: official identification
In France, identifying dogs and cats by microchip or tattoo is mandatory. It links the pet to its owner in the national I-CAD register. Its limitation: it can only be read with a scanner, which vets and pounds have. The person who finds your dog in the street cannot read it.
The engraved tag: readable, but fixed
A tag engraved with your number can be read by eye, by anyone. But space is limited, and if you change your number, you have to get a new one made.
The QR/NFC medallion: readable by anyone, up to date
The medallion can be read with any smartphone and opens a profile that you can change at any time: several contacts, useful information, lost mode. How it works is explained in how a QR/NFC medallion works.

Also remember to keep your contact details up to date on I-CAD: it is through this register that a vet or a pound will find you.
