Barcodes track products. QR codes track everything — with more data, easier scanning, and no expensive hardware. A QR code on a piece of equipment can link to its maintenance history, user manual, warranty info, and current location. A barcode can only store a number.
Here's how to set up QR-based inventory tracking.
Why QR Codes Over Barcodes for Inventory
More data capacity. A barcode holds 20-25 characters — enough for a product ID. A QR code holds up to 4,296 characters — enough for a URL linking to a full asset page with history, photos, and documents.
Easier to scan. QR codes scan from any angle, at greater distance, and with any smartphone camera. Barcodes require a specific scanner at a specific angle.
No hardware needed. Every employee has a phone. No need to buy dedicated barcode scanners.
Dynamic linking. A dynamic QR code links to a web page that you can update. The asset's status, location, maintenance log — all editable without changing the label.

How It Works
Simple setup (no special software)
- Create a spreadsheet with your assets: asset ID, name, location, URL to detail page
- For each asset, create a page with details (Google Doc, Google Sheet row, or a page in your inventory system)
- Generate QR codes for each URL at qree.app
- Print QR codes on durable labels
- Attach to assets
- When anyone needs info, they scan the QR → detail page opens
With bulk generation
If you have 100+ assets, use bulk QR generation. Upload a CSV or Excel file with asset IDs and URLs → download a ZIP with all QR code images → send to label printing.
What to Link To
The QR code is just the bridge. What it links to depends on your system:
Simple: Google Sheet. One row per asset. Columns: ID, name, location, purchase date, condition, notes. Each QR links to the specific row (using a filtered view URL). Free, easy to maintain, accessible to everyone.
Medium: Notion or Airtable. A database with richer fields: photos, documents, maintenance logs, assigned user. Each QR links to the asset's page. Free tier available.
Advanced: Dedicated inventory software. Sortly, Asset Panda, GoCodes, or your own system. Each asset has a URL in the software — QR links directly to it.
Custom: Your own web app. If you have internal tools, each asset page has a URL. QR links to inventory.yourcompany.com/asset/EXC-001.
Use Cases
Office equipment. Laptops, monitors, printers, chairs — each tagged with a QR. Scan to see who it's assigned to, when it was purchased, and warranty status. IT department saves hours on "whose laptop is this?"
Warehouse and logistics. Pallets, shelves, storage bins — QR on each location. Scan to see what's stored there, when it arrived, and where it's going.
Construction. Tools, machinery, safety equipment — QR on each item. Scan to see maintenance schedule, last inspection date, and certification status. See our construction QR guide.
Healthcare. Medical equipment, devices, wheelchairs — QR for tracking location, sterilization records, and maintenance logs. See our healthcare QR guide.
Schools and libraries. Laptops, projectors, lab equipment — QR for checkout tracking. Students scan to check out, scan again to return. See our education QR guide.
Fleet management. Vehicles, trucks, delivery vans — QR on each vehicle linking to mileage, service history, assigned driver, and insurance documents.
Label Printing
QR codes for inventory need to survive rough conditions.
Material: Use vinyl or polyester labels — waterproof, scratch-resistant, and durable. Paper labels will peel and fade within weeks.
Size: Minimum 2×2 cm for close-range scanning. 3×3 cm for equipment that's accessed frequently. 5×5 cm for warehouse bins scanned from arm's length.
Printing: Order from label printing services (Sticker Mule, Avery, Brady) or print in-house with a label printer. Upload SVG files from qree.app for perfect quality at any size.
Adhesive: Permanent adhesive for owned assets. Removable for leased or temporary equipment.
See our QR code stickers guide for more on materials and ordering.
Dynamic QR for Inventory
Use dynamic QR codes for every asset. Here's why:
Track scan frequency. If forklift #7's QR gets scanned 50 times a month and forklift #3 gets scanned twice — you know which equipment is heavily used and may need more frequent maintenance.
Update without relabeling. Moved your inventory system from a Google Sheet to Airtable? Update the redirect URL for all QR codes in your dashboard. No reprinting labels.
Deactivate lost assets. If equipment is decommissioned, deactivate the QR. Anyone who scans sees "This asset has been retired" instead of a broken link.
Tips
Standardize naming. Use consistent asset IDs: LAP-001, MON-042, FRK-007. This makes bulk generation and tracking manageable.
Start small. Don't tag 1,000 assets on day one. Start with 20-50 high-value or frequently-moved items. Validate the workflow, then scale.
Include the asset ID visually. Print the asset ID in text below the QR code on the label. If the QR is damaged or the phone battery is dead, someone can still look up the asset manually.
Train the team. Show everyone how to scan a QR code and what to expect. A 5-minute demo prevents confusion.
Create Your Inventory QR Codes
Generate QR codes individually or in bulk at qree.app. Dynamic codes with analytics — track which assets get scanned and when.
