Asset Tracking
A technician arrives at an HVAC unit. Without QR codes, they open the CMMS app, search by name or ID, scroll through results, and hope they selected the right asset. With a QR code, they point their phone camera at the label and the full asset record opens in under two seconds - maintenance history, manuals, open work orders, and the ability to submit a new request on the spot.
QR codes are the simplest, most cost-effective way to connect physical assets to digital records. This guide covers how to choose between tagging technologies, plan a rollout, select the right label materials, and integrate QR scanning into your CMMS workflows.

QR Codes vs Barcodes vs RFID
Three technologies dominate asset tagging. Each has clear strengths and trade-offs:

For most facility teams, QR codes are the best choice. They offer the best balance of cost, data capacity, and ease of adoption. Any smartphone can read them, they can link directly to web-based asset records, and they cost a fraction of RFID tags.
Implementation Guide
Step 1: Ensure Your Asset Register Is Complete
QR codes are only useful if each code links to a complete asset record. Before printing labels, verify that your CMMS has accurate data for each asset - name, location, type, install date, and maintenance history.
Step 2: Generate QR Codes from Your CMMS
Each QR code should encode the direct URL to the specific asset record in your CMMS. This ensures that scanning the code opens the right record instantly, without manual search or selection.
Step 3: Design and Print Labels
Include the QR code, asset name, and asset ID as human-readable text. Use a consistent size (typically 50mm x 25mm minimum) and placement standard. Choose label material appropriate for each environment.
Step 4: Deploy in Phases
Start with one building or one system type. Apply labels, test scanning with different phones in different lighting conditions, and confirm the workflow before scaling to the full portfolio. Rushing the rollout leads to misapplied or missing labels.
Choosing Label Materials
Indoor / Office Environments
Durable vinyl or polyester labels
Adhesive backing for smooth surfaces
Standard printing - thermal transfer or laser
Expected lifespan: 3-5 years
Harsh / Industrial Environments
Anodized aluminum or thick polyester with UV lamination
Chemical-resistant adhesive or mechanical fastening
Withstands temperature extremes, moisture, and UV
Expected lifespan: 10+ years
Always test a sample label in the target environment for 30 days before committing to a full rollout. Pay attention to adhesive performance on the specific surfaces (painted metal, plastic housings, concrete) your assets actually have.
Mobile Workflows with QR Scanning
QR codes unlock several high-value mobile workflows:
Instant asset lookup - scan to view the full asset record, maintenance history, and linked documents without searching
Work request submission - anyone can scan an asset and submit a maintenance request with photos, automatically linked to the correct asset
PM verification - scan the asset to confirm you are performing the PM on the right equipment, then complete the checklist on your phone
Condition documentation - scan, rate condition, attach photos, and the data flows directly into condition assessment and FCI calculations
Audit trail - every scan creates a timestamped record of who interacted with the asset and when, building an automatic activity log
Frequently Asked Questions
Why use QR codes for asset management?
QR codes provide instant access to asset information by scanning with any smartphone camera. They are inexpensive, hold more data than barcodes, and when linked to a CMMS, scanning opens the full asset record - history, manuals, condition data, and the ability to submit work requests on the spot.
What is the difference between QR codes, barcodes, and RFID?
Barcodes are cheap but limited in data and require dedicated readers. QR codes hold more data, work with any smartphone, and support URL links. RFID reads without line-of-sight at greater distances but costs significantly more per tag. For most facility teams, QR codes offer the best balance of cost and capability.
How do I create QR code labels for assets?
Generate QR codes from your CMMS, where each code links to the specific asset record URL. Print on durable materials suited to the environment. Include the asset name and ID as human-readable text. Use a consistent label size and placement standard.
What is the best QR code label material for harsh environments?
For harsh environments, use anodized aluminum or polyester labels with UV-resistant lamination. These withstand temperature extremes, moisture, chemicals, and UV exposure. Always test a sample label in the target environment for 30 days before a full rollout.
AssetLab generates QR codes for every asset, links them to full asset records, and supports mobile scanning for instant lookup, work request submission, and PM verification. Connect your physical assets to digital management in seconds.
