How to Use QR Codes for Equipment Identification and Work Orders
QR codes are the unsung heroes of CMMS. Cheap, simple, and incredibly effective.
A technician walks up to a machine, scans a QR code with their phone, and instantly sees:
- Equipment history
- Pending work orders
- PM schedules
- Manuals and schematics
Then they create a work order in 15 seconds โ equipment auto-identified, no typing.
QR codes transform CMMS from "office system" to "shop floor tool."
Here's how to deploy them effectively.
Why QR Codes Win
Cost
- QR codes: $0.01-0.10 each (printed)
- Barcodes: $0.05-0.50 each (need specialized labels)
- RFID tags: $1-10 each (plus readers at $500-5,000)
QR codes are essentially free.
Universal
Every smartphone can read QR codes. No specialized scanners needed.
Technicians use their own phones (BYOD) or company-issued devices.
Durable
Printed on the right material, QR codes last for years:
- Polyester labels: 3-5 years
- Anodized aluminum: 10+ years
- Epoxy domed: 5-10 years
Information Rich
A QR code can encode:
- URL (link to CMMS asset page)
- Plain text (asset ID)
- vCard (contact info)
- WiFi credentials
For CMMS, the URL approach is best โ it links directly to the asset record.
The Deployment Process
Step 1: Asset Inventory
Before tagging, know what you have.
- List all assets
- Verify locations (walk the floor)
- Assign unique IDs
- Record in CMMS
Step 2: Generate QR Codes
Your CMMS should generate QR codes automatically. If not, use an online generator.
The QR code encodes: https://yourcmms.com/asset/{asset_id}
When scanned, the phone opens the asset record directly.
Step 3: Choose Label Material
Match material to environment:
Office/Dry areas:
- Paper or basic polyester
- Cost: $0.01-0.05 each
Shop floor:
- Polyester or vinyl
- Cost: $0.05-0.20 each
- Lifespan: 3-5 years
Harsh environments (oil, chemicals, heat):
- Anodized aluminum
- Cost: $0.50-2.00 each
- Lifespan: 10+ years
Extreme environments:
- Epoxy domed labels
- Cost: $1-5 each
- Lifespan: 5-10 years
Step 4: Placement Strategy
Where to put QR codes:
- On the equipment โ Visible, accessible, cleanable
- At eye level โ Don't make technicians bend or climb
- Away from heat/moving parts โ Don't get burned or caught
- On a flat surface โ Easier to scan
- Consistent location โ Same spot on every machine (e.g., always on the control panel)
Where NOT to put QR codes:
- Inside cabinets (hard to access)
- On moving parts (gets damaged)
- Near heat sources (melts labels)
- Where oil/chemicals drip (obscures code)
Step 5: Apply Labels
Clean the surface โ Dirt and oil prevent adhesion Apply firmly โ Press out air bubbles Allow cure time โ 24 hours before exposure to chemicals Verify scan โ Test every code before moving on
Step 6: Train Technicians
Show technicians how to:
- Scan with their phone
- Access equipment info
- Create work orders
- View PM schedules
Make QR scanning the default way to interact with equipment.
The Workflows QR Codes Enable
Workflow 1: Quick Work Order Creation
Without QR:
- Open CMMS
- Search for equipment
- Navigate hierarchies
- Select equipment
- Create work order
- Fill details
- Time: 2-3 minutes
With QR:
- Scan QR code
- Tap "create work order"
- Add photo/note
- Submit
- Time: 15 seconds
Workflow 2: Equipment History Access
Technician walks up to machine. Scans QR. Sees:
- Every work order ever created
- Every PM ever performed
- Known issues
- Manuals and schematics
- Warranty info
No more "what's the history on this machine?" calls to the office.
Workflow 3: PM Execution
Technician scans QR. Sees pending PMs. Starts PM. Follows checklist on phone. Completes PM. Moves to next.
No paper checklists. No clipboards. No "where's the PM sheet?"
Workflow 4: Parts Identification
Technician scans QR. Sees BOM (bill of materials). Knows what parts are needed. Checks inventory. Orders if needed.
No more guessing part numbers or calling the warehouse.
Workflow 5: Safety Information
Technician scans QR. Sees:
- LOTO procedures
- Safety warnings
- Required PPE
- Emergency shutdown procedures
Safety info is always accessible, not buried in a binder.
Advanced QR Code Uses
Multi-Code Systems
Large equipment might have multiple QR codes:
- Main code on control panel โ general asset info
- Code on motor โ motor-specific history
- Code on gearbox โ gearbox-specific history
- Code on electrical panel โ electrical info
This enables component-level tracking.
Temporary QR Codes
For temporary equipment or rental machines:
- Generate temporary QR code
- Link to temporary asset record
- Remove when equipment leaves
QR Code Labels for Parts
Apply QR codes to parts bins:
- Scan to see parts info
- Scan to report low stock
- Scan to request reorder
QR Codes for Locations
Tag locations, not just equipment:
- Scan room QR โ see all equipment in room
- Scan aisle QR โ see all parts in aisle
- Scan utility QR โ see utility info (electrical panel, water shutoff)
Maintenance of QR Codes
Damaged Codes
QR codes get damaged. Plan for it.
- Inspect monthly โ During PMs, check that QR codes are scannable
- Replace promptly โ Damaged codes create friction
- Keep spares โ Have replacement labels ready
Code Standardization
Use consistent QR code formats across the plant:
- Same size (e.g., 2x2 inches)
- Same color (black on white)
- Same material (based on environment)
- Same placement (consistent location)
Database Updates
When equipment moves or is replaced:
- Update the asset record
- Generate new QR code if ID changed
- Verify old code redirects or is removed
Common Mistakes
Mistake 1: Cheap Labels in Harsh Environments
Paper labels on a pump that leaks oil. The code is unreadable in a week.
Fix: Match material to environment. Spend $1 on aluminum instead of $0.01 on paper.
Mistake 2: Poor Placement
QR code behind a guard that requires tools to remove. Nobody scans it.
Fix: Place codes where they're accessible without tools.
Mistake 3: No Verification
Codes generated but never tested. 20% don't scan.
Fix: Test every code immediately after application.
Mistake 4: Inconsistent Formats
Some codes link to CMMS. Some link to PDFs. Some are just text. Technicians don't know what to expect.
Fix: Standardize on URL-based codes that link to CMMS.
Mistake 5: Not Training Technicians
QR codes deployed but technicians still type asset numbers.
Fix: Train. Enforce. Make QR the only acceptable way to identify equipment.
The ROI
Cost: $500-2,000 for a typical plant (labels + labor)
Savings:
- 2-3 minutes saved per work order ร 50 work orders/day ร 250 days = 250-375 hours/year
- At $50/hour: $12,500-18,750/year in labor savings
- Plus: better data quality, faster problem resolution, improved safety
Payback: 1-3 months
The Bottom Line
QR codes are the cheapest, highest-ROI upgrade you can make to your CMMS.
They transform the system from "office tool" to "shop floor tool." They enable the 15-second work order. They make technicians faster, safer, and more effective.
Tag everything. Train everyone. Watch adoption soar.
