Everything about the PetID
The PetID is the smart tag on your dog's or cat's collar. Whoever finds the runaway scans it with their phone camera and sees everything that matters right now: name, temperament, quirks, your emergency notes. At that same moment you have the message on your phone and know where your dog or cat is. No app, no detour via the shelter. Here's how it works, why the PetID exists and what's inside it.

Why the PetID exists
And a neighbour who wanted to help — but didn't know how.
The cat is sitting on his patio, friendly, clearly missed by someone. The neighbour would call straight away — but call whom? Only a vet or animal shelter can read the microchip, with a scanner. The engraved tag shows a number from two house moves ago. So he does what everyone does: takes a photo for the neighbourhood group. And hopes.
Meanwhile you're walking the streets, printing flyers, phoning round the shelters. And all the while your cat is two gardens away on a stranger's sofa — with someone who this whole time needed just one thing: a way to reach you.
Hassle beats good intentions.
The PetID gives the neighbour that way: one scan, one message — and you know about each other.
„The world is full of neighbours who want to help. We make it easy for them.“
— Das SilentLink-Prinzip
The difference
The same open garden gate, two evenings — decided by what's on the collar.
Without the PetID
Hours to days
Your dog spends the night at the shelter. You spend it on the phone.
With the PetID
≈ 5 min
The moment of panic turns into a short walk.
How quickly a runaway comes home is decided by the way to reach you — not by luck.
The technology behind it
Three stops lie between the finder and your phone. None needs an app, none needs a scanner — and none needs the cat to be caught first.
Step 01
The ordinary phone camera opens a lean page with the profile you've set up: name, species, temperament and quirks — right through to emergency notes such as allergies or medication. The finder knows straight away how to approach your pet and what to watch out for.
Step 02
The finder picks between two reports: "Animal found", when it's safe with them, or "Animal spotted", when it moves on. Even a sighting gets you further — you know where to search. They share their location with one tap along with it.
Step 03
The message reaches you via WhatsApp, email or optionally SMS — with the find location as an address and map link. Replies travel back through SilentLink, and if it needs to be quick, the finder can call you directly — relayed through SilentLink, on the Premium plan. And you set off.
Your number stays invisible throughout — the relay runs encrypted via SilentLink.
Scan ≈ 00:02 min · "found" or "spotted" · find location by GPS
Location isn't reachability
GPS trackers for the collar are useful — as long as the battery is alive. But on the very night it matters, it's either charged or it isn't. Add to that subscription costs and a housing that's quickly too bulky for cats and small dogs. And even when the dot on the map is right: it doesn't tell the person currently stroking the runaway how to reach you.
The PetID has no battery, nothing to charge, nothing to maintain — it works on day one and on day one thousand. And it starts where a missing animal usually already is: with a person who wants to help. They scan, see your profile with your notes and report the find location. That's why many owners run two tracks — a tracker for searching, the PetID for being found.
Try it yourself
Point your phone camera at the code — you'll see exactly the page a finder sees after scanning: Luna's profile, two report options, one button. No download, no account.

Privacy as architecture
An engraving shows the same snapshot forever — often the one from two moves ago. The PetID's profile you maintain in the dashboard: temperament, quirks, emergency notes. The finder always sees the current version; the relay runs encrypted through SilentLink.

Understanding, not fine print
The questions we get asked most — answered the way we'd answer a friend.
The PetID is a smart pet tag with a QR code from SilentLink, built for the collar of dogs and cats. A finder scans it with their ordinary phone camera, sees the profile with name, temperament and your notes — and you get the report in seconds via WhatsApp, SMS or email. No battery, no app, nothing to charge.
No — it complements it. The microchip is the permanent identification, but only a vet or shelter can read it with a scanner. The PetID can be read by anyone with a smartphone: the neighbour, the passer-by out walking, the jogger. The chip proves who belongs to whom — the PetID makes sure it never has to come to the shelter in the first place.
The engraving shows your phone number to anyone who reads it — forever, even when it long since leads nowhere after a house move or a change of phone. The PetID flips that around: the finder reaches you instantly but never sees your data. And what they do see, you keep updated in the dashboard — instead of having a new tag engraved.
The two answer different questions. The tracker shows you a position — as long as the battery is alive and the subscription is running. The PetID needs no power and gives the person who found your dog or cat a direct line to you — with the find location by GPS. Many owners use both: a tracker for searching, the PetID for being found.
The profile you've set up — name, species, temperament, quirks and your emergency notes — and two reports: "Animal found" or "Animal spotted". Tap, write a quick note, send; no ads, no account, no app. You can view the page in the live demo — with demo dog Luna.
Yes: when sending, the finder shares their location with one tap — the find location then appears as an address with a map link right in your notification. Even a "spotted" report with a location helps enormously with the search.
Yes. The PetID is built for the collar and deliberately small and light — owners report that it barely stands out on the collar. And because it runs without a battery, there's nothing to charge and nothing to fail at the wrong moment.
Like every SilentLink ID, the PetID costs a one-off €24.99. After that the Starter plan is free forever, including WhatsApp notifications; Premium (€19.99/year or €2.49/month) is optional — all the details in the plan comparison. One plan covers all your IDs, from the collar to the car.

The next step
