How to label equipment with QR codes that last
By the CheckBadges team · Updated · 6 min read
The short answer
Number each machine, print a QR code with that number beside it, and stick it where the operator stands before starting, on a clean, flat spot away from heat and wash-downs. Use polyester or laminated labels outdoors, make the code big enough to scan from where people stand, test-scan every label, and replace any that fade or peel.
Key takeaways
- Put the code where the operator stands before starting: the dash, the control box, the cab door.
- Polyester or laminated labels outlast paper outdoors; metal tags suit the harshest spots.
- Bigger codes scan from farther away; leave a clear margin round every code.
- Print the machine's number in plain text next to the code.
- Static codes never expire; dynamic codes can be redirected but depend on a service.
Decide what the QR code should open
Decide what the code is for before you print anything, because it changes where the label goes. A code that opens a manual can go anywhere; a code that opens a pre-use checklist has to be where the check starts. The common choices are the label's own text (an asset number), a manual or spec sheet, a shared form, or a page made for that one machine, such as its checklist and history. Our QR codes for equipment page compares them.
The steps
Labelling a fleet properly takes eight steps, and most of the thinking happens in the first four:
- Decide what the code opens. A checklist, a manual, a form or just an asset number.
- Give every machine a number. A short, unique ID printed in plain text beside the code.
- Choose a label material. Paper indoors; polyester, laminate or metal outdoors and in harsh spots.
- Pick a size and print. Big enough to scan from where people stand, with a clear margin.
- Test-scan every label. Before it goes on the machine, with more than one phone.
- Clean the surface. Degrease, dry, and pick a flat spot away from heat.
- Place it where the operator stands. At eye level, where the check or task starts.
- Check labels and replace damaged ones. Make label condition part of the routine.
Number your equipment first
A QR code is only half a label; the other half is a number people can read without a phone. Use a short scheme with a prefix for the type and a number: FL-01 for forklifts, SL-02 for scissor lifts, EX-03 for excavators. Print it large beside the code, use the same ID on invoices, service records and the asset tag list, and never reuse a retired machine's number. When the code won't scan, the number still tells everyone which machine it is.
Where to put the label on each machine
Put the label where the person who needs it stands before they start, at eye level, on a flat panel that doesn't get hot, hit or hosed.
| Machine | Good spot | Avoid |
|---|---|---|
| Forklift | Overhead guard post beside the step, or the dash | Moving mast sections, chains, the counterweight |
| Scissor lift | Beside the platform control box; a second by the ground controls | The platform floor and gate |
| Boom lift | Platform control console or the ground control station | Boom sections out of reach |
| Excavator, loader, skid steer | Inside the cab by the door, or on the frame by the step | Engine covers, buckets, tracks |
| Truck, van, pickup | Inside the driver's door or on the door jamb | Outside panels that get washed or hit |
| Generator, compressor, welder | Beside the control panel or start switch | Exhaust and hot surfaces |
| Power tools | A flat part of the body | Grips that wear |
| Ladder | Side rail at eye height | Rungs and steps |
| Fire extinguisher, eyewash, AED | The wall or cabinet beside it | Anywhere it gets covered |
Label materials that survive
Match the label to where it lives. Paper is fine indoors; outdoors, oil, sun and pressure washing destroy it.
| Material | Good for | Watch out for |
|---|---|---|
| Paper labels | Indoors, out of the weather | Smudging, peeling, fading |
| Paper under clear laminate or packing tape | Indoors and sheltered outdoor spots | Edges lift if the surface isn't clean |
| Polyester or vinyl label stock | Outdoors, oil, wash-downs | Buy stock made for your printer type (laser or inkjet) |
| Laminated card tag on a zip tie | Curved, dirty or rough surfaces where nothing sticks | Can be torn off; tie it through two points |
| Metal asset tags | Heat, solvents and heavy wear | Ordered from a supplier, so slow to replace |
A clear matte laminate over the code doesn't stop it scanning; a glossy one can, if it catches the light.
Size, contrast and scan distance
Bigger codes scan from farther away. A common rule of thumb is a scan distance of up to about ten times the code's width, and phones often do better in good light. A code of about an inch (25 mm) is fine for scanning at arm's length; make it two inches or more if people scan from the ground or a step back.
Three other things matter as much as size:
- A clear margin. The QR standard calls for a blank "quiet zone" four modules (the small squares) wide around the code. Don't print it to the edge of the label or put text right against it.
- Contrast. Dark code on a light background, on a matte surface. Avoid colored or reversed codes for anything that has to scan in a dim cab.
- Short links. The fewer characters in the link, the fewer squares in the code, and the bigger each square is at the same printed size. Higher error correction lets a code survive scratches but adds squares, so there's a trade-off.
The free QR code label maker prints business-card or address-label sizes with the margin built in.
Applying labels so they stay on
Most labels fail because of the surface, not the label:
- Clean it. Wipe off oil and dust with isopropyl alcohol and let it dry completely.
- Pick a flat spot. Avoid rivets, seams, tight curves and anything that flexes.
- Mind the temperature. Adhesives bond poorly when cold; apply in a warm shop where you can, and follow the label stock's instructions.
- Press firmly from the middle outwards, then over the edges.
- Give it time to bond before pressure-washing, as the label maker advises.
Static vs dynamic QR codes
A static QR code contains the link itself. It never expires and needs no service, but if the page moves, you reprint. A dynamic QR code contains a short link from a QR service that redirects to your page, so you can change where it goes without reprinting, but it stops working if the service closes or your subscription lapses.
Codes issued by a checklist tool are a third kind: the code opens that tool's page for the machine, and the tool decides what it shows. In CheckBadges, a damaged or lost sticker is reissued in one click: the new code works, the old one stops, and the machine's history carries over.
Checking and replacing labels
Labels wear out, so make checking them routine. Add "QR label readable" as the last item on each machine's pre-use checklist, so the operator who struggles to scan it says so. Keep a spare printed set, and replace any label that's faded, scratched across the code or lifting at the edges, rather than waiting for it to fail. If you're setting up checklists from scratch, the full process is in how to set up QR code equipment checklists.
Frequently asked questions
What size should a QR code label be for equipment?
About an inch (25 mm) square is enough to scan at arm's length; go to two inches or more if people scan from the ground or a step away. A common rule of thumb is a scan distance of up to about ten times the code's width.
How do I make QR code labels weatherproof?
Print on polyester or vinyl label stock made for your printer, or laminate paper labels with a clear matte overlaminate. Clean and dry the surface first, and keep labels off hot or pressure-washed areas.
Do QR codes on equipment expire?
Static QR codes don't: the link is stored in the code. Dynamic codes from a QR service can stop working if the service ends or the subscription lapses. Either way, the code only works while the page it opens exists.
Can a QR code be scanned through laminate?
Yes. Clear laminate doesn't stop a scan, but a glossy finish can cause glare under lights or sun, so matte laminate is more reliable.
Where should a QR code go on a forklift?
Where the operator stands before getting on: the overhead guard post beside the step, or the dash. Keep it off moving mast sections, chains and the counterweight.
