The detail that matters

It's not a GPS.
But it tells you where it's been seen.

Whoever finds your pet holds their phone to the tag and, with one tap, alerts you. If they share their location, you get an alert and a map with the spot where they saw it, even in another city. And if you turn it on, we also let you know about every scan.

  • Scan location on the map

    From the phone that scans it, if that person agrees to share it.

  • Real-time push notification

    It reaches you before the person has finished reading the passport.

  • Direct contact with whoever scans

    Call and message button without sharing your private number.

  • Complete scan history

    Every read is logged in their digital passport.

More than a collar

What gets unlocked with a scan.

The collar is the key. Behind it lies a complete ecosystem that protects your pet, connects with vets and builds a little social network among the neighbourhood's furry friends.

Safety

S.O.S. mode Activated.

If your pet gets lost, you turn on S.O.S mode from your dashboard. The public page shows a red "Lost pet" banner; your phone number only appears if you turn it on. Whoever scans the tag can alert you with one tap, with their location if they share it.

SOS · active for 14 min
Identity

Digital passport permanent.

Every pet has a passport number that never changes, and every tag a unique MZ- code. Photo, name, breed, age and microchip. Edit it whenever you like without reprinting anything, and link several tags to the same pet.

Health

Medical record universal.

Any vet in the Mizuu network scans the collar and accesses the full history: vaccines, allergies, weight, previous treatments. They can add new events instantly. A second opinion without requesting reports or making copies.

Community

A social network among pets.

When another owner visits your pet's passport, they can send theirs as a “buddy” of yours. You build a network of furry friends who cross paths at the park, on the beach or in the lift. Arrange walks together straight from the app.

How it works

Three steps. No cables.

01

Link the collar

Hold the collar to your phone. The first time, it takes you to Mizuu to associate it with your pet's passport. Thirty seconds.

02

They wear it

Resistant to water, mud and rough play. No battery to charge, no app to update. It works for the whole life of the collar.

03

If they're found

Whoever scans it can alert you with one tap (it reaches you instantly), with their location if they share it, and leave you a message without seeing your details. If you turn it on, we alert you on every scan. In S.O.S mode, a warning banner is shown too.

Frequently asked questions

What people ask us.

How do I receive the location when someone scans it?+
Whoever finds your pet taps "Alert the owner" and their browser asks for location permission. If they allow it, you get an alert with a map of the spot; if not, you still get the alert and, if they leave their contact, a message. If you turn on "Alert me on every scan" in Papers, we also let you know when someone scans it without tapping.
Does it work with iPhone?+
Yes. Any iPhone XS or later (iOS 14+) reads NFC natively. Hold the top of the phone to the collar, a notification appears, and tapping it opens the passport. No need to install anything.
And if I lose my pet?+
You turn on S.O.S mode from your dashboard. The public page shows a red "Lost pet" banner and whoever scans the tag can alert you with one tap, with their location if they share it, or leave you a message with their contact details. Your phone number is only shown if you turn it on for the S.O.S; your email and address, never.
Is it water-resistant?+
Yes, it handles rain, mud and everyday splashes. It has no waterproof certification, so if your pet swims often, dry it afterwards and check now and then that the ring is properly closed.
Does it replace the microchip?+
No: it complements it. The microchip is the identification required by law (Spanish Law 7/2023) and is read by a vet or shelter with a specific reader. The Mizuu NFC tag can be read by any neighbour who finds your pet, right there, with their phone, which is when reunions usually happen.
And if I lose or break the collar?+
If it fails, we replace it free of charge: you have the 3-year legal guarantee. If you lose it, buy a new one and link it to your pet in under a minute; the old one is unlinked and your pet’s digital passport stays intact.
Are there monthly fees?+
No. You pay once (19,90 €) and it lasts the whole life of the collar. No subscriptions, no renewals, no surprises. The digital passport page and all features (scans, alerts, veterinary history) are included forever.
