A QR code is only half the job

A code that scans first time, from the right distance, in poor light, has done its job. Then it opens a homepage: a cookie banner, a navigation bar, a hero image sized for a desktop monitor, and somewhere below the fold the thing the poster was actually about. The person scanning is standing up, holding a phone at arm’s length, with about eight seconds of patience. They leave, and the campaign reports a scan.

That page is usually not anybody’s fault. It was written for a visitor who arrived by search, with intent, on a laptop. A scan is the opposite of that: no intent, no context, one thumb. It needs its own page, and building one per campaign is exactly the job that never gets done — so the code gets pointed at the homepage and the scan is wasted.

You are not designing anything. You pick what you are printing for and answer the questions that layout asks: the menu preset wants the menu link, the sections, and the kitchen hours. The offer preset wants the code, where it is redeemed, and when it expires. The event preset wants the date, the door time and the address.

Nothing asks you to choose a font, a column width, or where a button goes. Every page starts filled in with real copy rather than placeholder text, so a page saved half-finished still reads like a page somebody wrote — which matters, because the code is going to the printer either way.

Every preset is built around a single button. Everything else on the page — the secondary links, the details list, the small print — sits under it and exists to support the decision, not to compete with it. There is no navigation, because there is nowhere else to go: this is a page somebody reached by pointing a camera at a thing in the world, and the only useful outcome is the one the thing was advertising.

The page is mobile-first in the literal sense: it is designed at phone width and it happens to work on a laptop, rather than the other way round. It carries no tracking scripts of its own and loads as one document, so it opens on a hotel Wi-Fi or half a bar of signal.

The address stays the same, so the code stays the same. Change the offer, swap the menu link, move the event, and every code already on a wall starts showing the new page. That is the same promise a dynamic QR code makes about its destination, extended to the destination itself.

When a campaign ends you pause the page rather than deleting it. The code is still on the poster, and a “not found” is a better thing to find than an offer that expired three months ago. Views are counted the way scans are — link unfurlers and crawlers are filtered out, so the number is people.
