QR sticker for your car — reachable without sharing your number
Leaving your phone number on the dashboard used to be the only way to be reachable. It's also a standing invitation to spam, scam calls, and anyone who walks past. A ContaQ Live QR sticker gives you the same reachability with none of the exposure.
What a car QR sticker does
The sticker carries a code that's unique to your vehicle. If someone needs to tell you something — you're blocking them, your lights are on, a window is open — they scan it with their phone camera and get a simple page to call or message you.
The contact is relayed through ContaQ Live, so your real number is never shown, and neither is theirs. It's privacy on both sides.
How to set it up
- Join the waitlist at contaq.live and get your invite.
- Install the ContaQ Live app and add your vehicle (number plate and basic details).
- Generate your QR code — it's specific to that car.
- Print the sticker and place it on the vehicle.
Set it up once; the car stays reachable every time you park.
Where to place it
- Side window — easy to scan from the pavement.
- Lower windscreen — visible but out of the driver's eyeline.
- Rear glass — good for cars often parked in tight rows.
Pick a spot that's readable from outside, protected from rain, and doesn't sit in your field of view while driving.
Why not just write your number on the dash?
- Anyone who walks past can copy your number.
- It exposes you to spam, marketing calls, and misuse.
- You can't turn it off or change it without a new note.
- It's visible even when you'd rather stay private.
With ContaQ Live, you can be reached when someone actually needs you — and nobody collects your number in the process.
Frequently asked questions
How does a QR sticker for a car work?
It's unique to your vehicle. Anyone who scans it can call or message you through ContaQ Live, and your real number is never shown.
Does the other person need an app?
No. They just scan with their phone camera. Only you need the app to register the vehicle and generate the sticker.
Where should I put it on my car?
Side window, lower windscreen, or rear glass — visible from outside, without being in the driver's line of sight.
