About this product
A SeQR pet tag works like a normal collar tag, except thereโs no phone number on it. Whoever finds your dog or cat points their phone camera at the code, and a page opens with your petโs name and your note, a message box, and a button to share where they are. You reply straight away. Your number and address don't appear on the tag.
Itโs small and light enough for a cat or a toy breed, and tough enough for a big dog that plays rough. It sits quietly on the collar: no metal-on-metal jingle, no scratched-off engraving. The code is sealed under acrylic, so it stays readable through rain, mud and years of rubbing against the ring.
Itโs the same tag we sell for keys, on a steel split key ring that fits any collar or harness ring. Put the first one on the collar, the second on the harness, and the rest wherever youโd hate to lose something: your keys, the leash, the carrier. Every tag has its own code and sits in one free account, where you name each one so you know which was scanned.

Most pet tags hand your phone number to whoever reads them.
An engraved tag works because anyone can read it. Thatโs also the problem: your number, and sometimes your address, is on show to every stranger your pet meets. It jingles against the ring and the engraving wears smooth in a few years. A microchip keeps your details private, but only a vet or a shelter can read it.
A tag on the collar does nothing on the walk
Most dogs wear a harness outside and a collar at home. Tag both, and your pet is covered whichever one they slipped out in.
Microchips need a scanner
A chip only helps once your pet reaches a vet or a shelter. The neighbour who finds them in the street canโt read it.
A phone number only works if you pick up
8 in 10 Americans donโt answer calls from unknown numbers (Pew Research Center), and many phones silence them automatically. SeQR sends the finderโs message to your texts, email and phone, so you see it.
SeQR is the private way to tag a collar, and a harness
Two tags for the pet, two for your keys, one account. Small, quiet and light enough for a cat. Whoever finds your pet scans the tag and messages you, and you see it by text, email and push alert. They don't see your name, number or address.
One tag, many places
Pet tags and keychain tags are the same tag. Every one has its own code and its own name in one free account, so four tags look like this:
- Biscuitcollar
- Biscuitharness
- House keyskey hook
- Car keysHonda
Rename any tag, change any note, see which one was scanned.
-
Collar and harness
Where the first pair goes. Quiet, light enough for a cat, and your pet is covered at home and on the walk.
-
Your keys
The same tag as our keychain pack. The split ring goes straight on your keys, and nothing on it says which door it opens.
-
Leash and carrier
Everything that leaves the house with the dog. A stranger at the airport finds the carrier, not the collar.
-
Two pets
Each tag has its own code and its own name, like โBiscuitโ and โLunaโ.
-
The next collar
Cat collars are designed to come off. A tag isnโt assigned to anything until you scan it, so the spare one waits in the drawer.
-
Familyโs bags and gear
A backpack, a lunch bag, a bike. If it has a ring or a zipper pull, it can wear a tag.
How it works
If you can take a photo with your phone, you can use SeQR.
-
Step 1
Clip it to the collar and scan it once
Attach the tag to your petโs collar and point your phoneโs camera at the code. Add your petโs name and a short note, like โFriendly, but nervous around traffic.โ
-
Step 2
Someone finds your pet
They scan the tag with any phone camera. A page opens with your note, a message box and a button to share where they are. No app, no account.
-
Step 3
You see it, wherever you are
We alert you right away by text, email and push notification, so you see it even if your phone silences unknown callers. Your number and address stay hidden; you decide what to share and where to meet.

A real SeQR demo tag
Try it before you buy
Point your phone's camera at this code. The page that opens is exactly what a finder sees when they scan one of your tags.
- Open the camera on your phone
- Point it at the code
- Tap the link that appears
It's a demo tag that belongs to us at SeQR, so go ahead and send a message. You'll see it arrive without anyone seeing your number.
What a finder sees, and what they don't
They see
- Your petโs name and the note you wrote
- A box to send you a message
- A button to share where they found your pet, if they choose
They don't see
- Your name
- Your phone number
- Your email
- Your home address
We do not sell or share your information.

Customer Reviews
Good size
The pet tags are very easy to set up, small and give great peace of mind in the event our pet gets away from us.
We had an issue with the delivery of our item and needed to contact customer service and had the best experience ever. The owner made sure our tags were delivered to us right away and worked with us to get a back up order. We had excellent communication from the company. FIRST RATE SERVICE!
easy to use-can store all the data I need--a great idea that was well executed
Questions and answers
Why two tags?
Because your pet wears more than one thing. A tag on the collar does nothing on the walk if they go out in a harness, and a catโs breakaway collar is designed to come off. Tag the collar and the harness, then put the next two on your keys. Each tag has its own code and its own name in your account.
How do I customize my tag? Do I need to send my details when I order?
No. Thereโs nothing to fill in when you order: every tag arrives blank and ready to set up, and you personalize it yourself once it arrives. Give it a name, like โBiscuitโs collarโ, write the note a finder will see, and choose how youโd like to be alerted. You can change any of it later, as often as you like.
How do I activate my tag?
Open your phoneโs camera, point it at the code and tap the link that appears. Setup takes about 30 seconds in your phoneโs browser. Use the camera app that came with your phone, not a third-party QR scanner app, so the setup page opens correctly. You donโt need an app, but if youโd like one, the SeQR app is at install.page/seqr. It isnโt in the Apple App Store or Google Play, so install it from that link.
Can I put one on my keys or a bag?
Yes, and thatโs what the 4-tag pack is for. Pet tags and keychain tags are the same tag; the steel split key ring goes on your keys, a zipper pull or a leash handle. Two for the pet, two for your keys.
What if I donโt answer calls from numbers I donโt know?
Youโre not alone: 8 in 10 Americans say they donโt answer calls from unknown numbers (Pew Research Center, 2020). Thatโs why SeQR doesnโt rely on a phone call. The finder sends a message, and you get it by text, email and push notification, whichever you turn on. You reply when you see it, and your number stays private.
Can I buy just one?
The pair is the only size. Nearly everyone needs the second tag within a month, for a harness, a new collar or a second pet, and two together cost less than buying one at a time.
Will it fit my dogโs or catโs collar?
Yes. The steel split key ring fits any standard collar or harness ring, including a catโs breakaway collar. The tag is light enough for a cat or a toy breed, tough enough for big dogs that play rough, and it doesnโt jingle against the ring.
How well does it hold up?
Very well. The code is sealed under acrylic rather than stamped on the surface, so it doesnโt scratch or wear smooth the way engraving does, and it shrugs off rain, mud and years of rubbing against the collar ring. If one ever stops scanning within the first year, we replace it.
Does my pet need a microchip too?
A microchip is still worth having, since vets and shelters scan for it. The SeQR tag covers the moment a neighbour or passer-by finds your pet and wants to reach you on the spot.
What does the finder see?
Your petโs name, the note you wrote, a message box and a button to share where they are. They don't see your name, number or address. Each tag shows its own name and note, so the collar tag and the harness tag can say different things.
Can I add things like โneeds medicationโ or a sitterโs details?
Yes. The note is yours to write and change anytime: your petโs name, that theyโre nervous with strangers, that they need medication, or who to contact while youโre away.
How will I know if someone scans it?
Youโll get a message by email, text or phone notification, whichever you choose. You can reply right away, and the person who scanned it doesn't see your contact details.
Do I or the finder need an app?
No. You set up your tag in your phoneโs web browser, and the finderโs camera simply opens a web page with a message box. Nobody has to download anything. If youโd like an app anyway, ours is at install.page/seqr (it isnโt in the App Store or Google Play).
What does SeQR do with my information?
Your contact details are only used to deliver messages from people who scan your tags. We do not sell or share your information.
What if my phone number or email changes?
Nothing to replace. Update your details in your SeQR account and every tag you own follows. The code on the tag stays the same.
Does it work outside the US?
Yes, anywhere with internet. Scanning the tag opens a web page, so the finder doesnโt need to make an international call or have a US number.
Is there a monthly fee?
No. You pay once for the tags, and messaging is included for life.
