QR code types that are actually useful on site
Not a feature list — a straight answer to one question per type: which piece of paper does it replace?
Contents
Built for site work
Six types designed for the field. Each one replaces a piece of paper that goes missing — a register, a permit, a delivery note, a log, an induction folder.
Site sign-in
Displayed at the site entrance: people scan in and out from their own phone. Times are stamped by our servers and the position is verified, so the register cannot be filled in from the van. Replaces the paper attendance sheet.
See the sign-in sheet and QR check-inPermit to work
Hot work, work at height, confined spaces, electrical work: the permit is signed on the spot and time-stamped by our servers, and it expires on its own at the end of the window. Require a validated position, and it can no longer be signed from the depot.
See the hot work permit in detailDelivery receipt
At the delivery area: whoever takes the delivery records its condition (accepted, partial, damaged, refused), photographs it, notes any reservations and signs. A time-stamped record for every drop.
See the goods received note and QR delivery recordEquipment record
Stuck on the machine: manual, warranty, service contact, and a maintenance log that anyone adds to by scanning. The documentation follows the equipment instead of sitting in a folder.
See the equipment maintenance log in detailSite induction
The site rules displayed at the gate: everyone scans on arrival, reads them and confirms they have done so. Each acknowledgement is time-stamped by our servers and keeps the exact text that was read — change the rules mid-job without reprinting anything.
See the site induction form and QR versionLog
The log on its own, with no asset to describe: who came past, when, what they found. Two fields on scan, optional photos, time taken server-side. Welfare units, security rounds, readings, plant checks.
See the site log sheet in detailDocuments and media
The workhorses. A code on a door, a riser or a drawing board, and the current version is two seconds away — whoever scans it needs no account.
Documents (PDF and images)
Several files behind one code, organised: drawings, method statements, data sheets, certificates. You replace a file and every printed code points at the new version — nothing to reprint.
Photo gallery
A set of photographs in one code: progress records, as-found condition before works, a handover album. Three display layouts to choose from.
Video
A short demonstration is worth three pages of method statement, especially for a task done once a year. Hosted elsewhere, reached by the code.
Audio
A spoken instruction for a noisy or awkward spot, or for a team that would rather listen than read a laminated sheet in the rain.
Text
Plain text, no file. Emergency arrangements, a gate code, a delivery instruction, a phone number — the things that end up written on a scrap of paper.
Links and redirects
The distinction that matters before you print anything: a static code is fixed forever, a dynamic one can be pointed somewhere else after it is on the wall.
Static URL
The address is written into the code itself. Free, permanent, works with no service behind it — and impossible to change once printed. Right for something that will genuinely never move.
Dynamic URL
The code points at us, and we point at your destination. You can change where it goes after printing, and you see how many times it was scanned. This is what makes a code survive a change of plan.
GPS directions
A page that gets people to the right gate: your access instructions first (who to report to, what PPE, where to park), then directions to the exact point — the delivery entrance, the compound — in Google Maps, Waze or Apple Maps. The location can be changed without reprinting. Useful when the postal address puts drivers on the wrong side of a fence.
Everyday odds and ends
Not construction-specific, but they earn their place in a site office.
Wi-Fi
Scan and connect, without reading a 24-character password off a laminated card. Stuck on the wall of the site office.
Contact card
Name, role, phone, email saved into the phone in one scan. On a helmet sticker, a site board or a business card.
Payment link
A payment page reached by scanning. Occasional, but it saves chasing an invoice for a small job.
Choosing a type — frequently asked questions
Static or dynamic — which should I print?
Dynamic, in almost every case on a construction site. A static code carries its destination inside itself: free and permanent, but frozen the moment it is printed, and printed things on a site outlive the plan they were made for. A dynamic code can be repointed after the sticker is on the wall, and it tells you whether anyone actually scanned it.
Do people need an app to scan?
No. Every phone made in the last several years reads QR codes from the camera app, with nothing to install. And nobody scanning your code needs an account with us — that matters more than it sounds, because a subcontractor there for one day will not sign up for anything.
What happens if there is no signal?
Scanning opens a web page, so it needs a connection. Basements, lift shafts and steel structures are exactly where phones struggle, and we would rather say so than pretend otherwise. QR codes replace the folder in the site office; they do not replace the printed sheet you put where you know there is no signal.
Can I control who sees what is behind a code?
Yes, two ways, and they combine. A 4-digit PIN, and geofencing — the code only opens for a phone genuinely on the site, checked on our servers rather than trusted from the phone. On a permit, geofencing is checked at the moment of signing rather than on opening. Where GPS cannot reach, a fallback code keeps signing possible, and those signatures are flagged as such.
Do the codes expire?
The printed code does not stop working on its own. What can expire is what sits behind it — a permit closes at the end of its window by design. And because dynamic codes are repointable, a code on a hoarding can be given a new job at the end of the project rather than being thrown away.
