Car QR code tags: what they are and how they work in India
A car QR code tag is a sticker or tag with a QR code that you fix to your vehicle. When someone scans it, they can reach you about the car — a blocked driveway, a small accident, a tow warning, a lost pet — without ever seeing your phone number. This page explains how it works, where to put it, and how it is different from FASTag and the number plate.
What is a car QR code?
A car QR code is simply a QR code — the square, scannable pattern — printed on a sticker, card, keychain or metal tag and attached to a vehicle. Point a phone camera at it and it opens a web page tied to that specific vehicle. What that page shows is up to the owner. With a caraadhar tag, the page is a private contact screen: a visitor can call, message on WhatsApp, or raise an emergency alert, and the actual phone number of the owner is never revealed.
The important part is that nothing personal is stored in the code itself. It holds a random web address and nothing else. Your phone number, emergency contact and vehicle details sit in your account, each with its own privacy switch, so you can change or hide any of them without ever reprinting the sticker.
How a caraadhar car QR code works
- 01
Fix the QR code tag to the vehicle
A sticker on the windscreen or rear window, a card in the dashboard, a keychain on the bike, or a small tag on a pet's collar.
- 02
Link your phone number once
Register the tag to your number over a call, or do it yourself from the Activate a tag page. An OTP confirms it is really you.
- 03
Fill in what you want shown
Vehicle name and model, an emergency contact, a note. Every field has its own privacy switch — show it, or keep it hidden.
- 04
Anyone can now scan it
A phone camera opens the vehicle's private page. The visitor can call, message on WhatsApp, or raise an emergency alert — your number never appears.
Where people put a car QR code sticker
- Inside the windscreen, bottom corner, facing out
- Rear windscreen for cars that get blocked in tight lanes
- Dashboard as a card, for when the glass is tinted
- Bike or scooter — keychain tag or a sticker on the mudguard
- Helmet, for two-wheeler riders
- Pet collar, so a found dog or cat gets home
Why not just leave your number on the dashboard?
A phone number written on a slip of paper works — and it hands your number to every person who walks past the car, to be copied, saved or misused. A car QR code puts a screen between you and the stranger. They get a way to reach you; you get to decide what they see and can switch calling off entirely and take messages only. If you sell the vehicle or change your number, you edit a form instead of scraping off a sticker.
Car QR code vs FASTag vs number plate
Number plate
Legally required, publicly visible, and not something you control. A car QR code does not replace it.
FASTag
An RFID sticker scanned by toll plazas to charge toll. It is about payments, is read by fixed scanners, and cannot be used by a passer-by.
Car QR code tag (caraadhar)
Read by any phone camera. It is about being reachable in an emergency while keeping your number private. Owner-controlled and editable any time.
Common questions
What is a car QR code?
A car QR code is a QR code printed on a sticker, card or tag and fixed to a vehicle. Scanning it with a phone opens a web page linked to that vehicle. With caraadhar, that page lets a stranger contact the owner in an emergency without seeing the owner's phone number.
Is a car QR code the same as FASTag?
No. FASTag is an RFID sticker read by toll-plaza scanners to deduct toll automatically. A caraadhar car QR code is read by an ordinary phone camera and is about reaching the owner — wrong parking, an accident, a tow — not payments.
Does a car QR code replace the number plate?
No. The number plate is a legal requirement and stays as it is. A car QR code sticker sits alongside it and adds a private, owner-controlled way to be contacted.
Can anyone find my details by scanning the QR code?
They only see what you have chosen to show. The QR code itself holds nothing but a random web address; your number, address and contacts live in your account behind per-field privacy switches.
What happens when someone scans my car QR code?
They land on your vehicle's page with buttons to call, WhatsApp or send an emergency alert. You receive the message and their number; they never receive yours unless you switch it on.
How much does a car QR code tag cost in India?
caraadhar tags start at ₹199 including shipping across India. There is no subscription — you pay once and the tag works for life, with unlimited scans and edits.
Do I need an app to scan a car QR code?
No. Every recent Android and iPhone camera reads QR codes natively. The owner also does not need an app — the dashboard is a normal website.
