How it works
Three steps. No pen, no paper, no waiting.
Until now the fastest way to reach a car owner was a note under the wiper — hoping it doesn't blow away, and hoping they come back before the tow truck does.
Stick it on anything
Windshield, keyring, suitcase handle, laptop lid. Any QR reader can open it — the Ottomon app makes it one tap.
Get notified instantly
Someone scans, picks a message, and you get a real-time alert. Reply if you want to — or don't. Your identity stays yours.
Use cases
Built for the moments you wish someone could just tell you.
Every one of these used to end with a ticket, a tow, or a lost item. Now it ends with a notification.
Blocking a driveway
"Your car is blocking the way." Sent in seconds, before anyone calls a tow.
About to be towed
Street cleaning, wrong zone, blocked hydrant — you hear about it in time to move.
Ticket incoming
A warning from a stranger costs nothing. A parking ticket does not.
Lights left on
Jump-start avoided. Battery saved. One scan from a passing stranger.
Meter expiring
Get a nudge before the enforcement officer gets there.
Lost luggage
Tag your suitcase and the finder can reach you without knowing who you are.
Lost keys
Whoever picks them up can reach you immediately — no keychain address tag needed.
Lost laptop
Tag the lid. A coffee shop, a cab, an airport lounge — someone can let you know.
Privacy first
Be reachable. Not exposed.
You should never have to write your phone number on your windshield to be a good samaritan's neighbour. Ottomon was designed so you never have to.

Communication
Pre-written when speed matters. Open when it doesn't.
For vehicles, scanners can send one-tap canned messages — fast to send, impossible to abuse. Once both sides choose to talk, a private thread opens.
- No phone numbers, emails, or addresses are ever exchanged
- Owners choose whether custom messages are allowed
- Threads can be blocked, muted, or deleted at any time

FAQ
Questions, answered.
Does the scanner see my name or phone number?
No. That's the entire point. A scanner sees the object type (for example, "Vehicle") and, if you choose, a display name you set yourself. Your email, phone number, and address are never exposed through the tag.
Do they need the Ottomon app to scan my tag?
No. Any standard QR code reader will open the tag page. Installing the Ottomon app just makes it faster and lets the scanner track replies in one place.
What stops someone from spamming me?
For vehicles, scanners can only send pre-written messages by default. Rate limiting applies per tag and per device, and you can block a thread or turn off custom messages entirely at any time.
Can I take a tag out of circulation?
Yes. Deactivate or delete any tag from your dashboard and it stops resolving immediately. If you sold the car, reassign the tag to a new object instead.
What happens to my messages?
Messages live in a private thread visible only to you and the scanner. You control the retention window, and you can delete a thread whenever you want. Account deletion removes your data.
Is it really free?
Generating and printing digital ottotags is free, with no cap on how many you create. Premium physical tags are sold at cost-plus as an optional convenience.
When does Ottomon launch?
Early access is rolling out in stages. Join the waitlist and you'll get an invite as soon as tags are available in your region.
