QR codes for car stickers

A car-sticker QR code turns time in traffic into scans: drivers at red lights and in parking lots scan your rear window or bumper. It is free on Quardzy, and each scan shows a short ad before your link, so a captive audience with high dwell time earns you ad revenue.

Red lights and car parks are ideal — a captive audience with time to scan. Place the code on the rear window or bumper where the car behind can see it.

Point it at your business, socials, or a promo, and update the destination anytime without a new sticker.

Frequently asked questions

Is it safe to put a QR code on my car?

It only encodes a link — nothing about you personally. Use a link that does not expose private details.

How big should the sticker be?

Aim for 8–12 cm so it scans from a car length or two away at a stop.
