# QR codes on vehicle wraps

> A vehicle QR code only works when the vehicle is parked. On the move it is unscannable at any size. Size for the parked case — 20–50 cm — and put it on the side panel, not a curved or hinged surface.

## Parked is the only case that matters

A moving vehicle cannot be scanned. All the value is in the parked van outside a customer's
house, at a depot, or at a trade show. Design for a pedestrian standing 2–3 m away: 20–30 cm
of code.

## Where to put it

- **Rear doors** and the **rear quarter of the side panel** — the flattest, most accessible
  areas.
- Avoid door handles, hinges, fuel flaps, mirrors and body swage lines. Any crease across
  the code kills it.
- Keep clear of the wheel arch — road spray covers everything below about a metre.

## Material and finish

Cast vinyl with a **matt** laminate. Gloss on a car in daylight is unreadable. Matt also
survives the wash better.

## What it should link to

Something a person standing beside a parked van actually wants: a quote request, a phone
number, availability. Not a homepage.
