In manufacturing, a QR code on a machine, part or crate replaces a laminated binder: it opens the current manual, the maintenance log, the spare-parts list or a safety procedure for exactly that asset. The code identifies the item; the content lives online and can be updated centrally.
What are the main manufacturing uses?
| Use | Where the code sits | What it opens |
|---|---|---|
| Equipment manuals | Machine panel | Current manual, quick-start video |
| Maintenance | Near service points | Checklist, log entry form, last service date |
| Spare parts | Inside cover or frame | Part numbers, order page |
| Safety and lockout | Next to hazards | Procedure, SDS, contact for incidents |
| Work-in-progress tracking | Bin, tray or traveller | Order, batch and station record |
| Product end of line | Product plate | Warranty registration, support, manual |
For asset registers see the asset tracking guide.
Are digital instructions allowed instead of paper?
In many markets, yes, with conditions. The EU Machinery Regulation (EU) 2023/1230, which applies from 20 January 2027, permits instructions to be supplied in digital form, with the user able to request a paper copy. Check the exact conditions for your product and market, and confirm with your compliance advisor. The same logic applies to product passports; see the Digital Product Passport guide.

How do you make a shop-floor code last?
- Use durable media: polyester or polycarbonate labels with a laminate, or laser-etched metal plates, for oil, heat and cleaning chemicals.
- Print larger than you think: gloves, grease and dim light degrade scanning. 3 to 5 cm is a reasonable start for a code read at arm's length; see the print size guide.
- Use a higher error-correction level: abrasion and scratches remove modules, as explained in error correction levels.
- Test with the real scanners: phones, rugged handhelds and fixed readers behave differently on curved or shiny surfaces.
- Consider DataMatrix for tiny parts: where direct part marking is required, a customer or industry standard may specify it instead of QR; see the packaging guide for the decision.
How do you keep content current?
Use one URL per asset, never one per file. Printing a direct link to "manual_v3.pdf" breaks the day someone renames it. Use a dynamic QR code or your own redirect so an updated manual replaces the old one without touching the plant floor. Control access: public codes should not expose internal procedures. Protect internal pages with sign-in, and read the QR code safety guide before labelling anything a visitor can reach.
