QR Codes for Inventory Management

QR codes offer more flexibility than traditional barcodes—they hold more data, scan from any angle, and work with smartphone cameras. Learn when to use QR codes for inventory, what data to encode, and how to implement them effectively.

Why QR Codes for Inventory?

QR codes offer unique advantages over traditional barcodes for certain use cases.

More Data Capacity

QR codes hold up to 4,000 characters vs. 20-25 for barcodes. Encode URLs, detailed specs, or multiple data fields.

Phone Scanning

Any smartphone camera can scan QR codes. No dedicated scanner needed—perfect for mobile teams and field use.

Scan from Any Angle

QR codes scan from any direction. Unlike barcodes that need horizontal alignment, QR codes are forgiving.

Recommendation: Use QR codes when you need richer data, phone-based scanning, or customer/public-facing labels. Use traditional barcodes for high-speed checkout, warehouse picking, and when dedicated scanners are available.

QR Code Inventory Use Cases

Where QR codes add the most value.

Asset Tracking

Track equipment, tools, and fixed assets. QR code links to maintenance history, warranty info, and assignment records. Scan to check out or log service.

EquipmentToolsIT Assets

Location Labels

Label shelves, bins, and zones with QR codes. Scan to see all items at that location, or to assign items during put-away. Speeds up warehouse navigation.

WarehouseStorageShelving

Field Service

Technicians scan QR codes on equipment to access manuals, log service, or order parts. No app needed—just a phone camera and a URL.

MaintenanceRepairsHVAC

Receiving & Put-Away

Include QR codes on shipment labels or pallets. Scan to receive entire shipment, view contents, or update inventory—faster than scanning individual items.

Consumables & Supplies

Post QR codes near supply cabinets. Staff scan to request restock, log usage, or see supply levels. Low barrier—no training needed.

Customer-Facing Products

QR codes on products can link to manuals, warranty registration, or reorder pages. Customers scan with their phones—no app required.

What to Encode in Inventory QR Codes

Keep it simple—more data means larger QR codes. Choose based on your use case.

Simple: Item ID Only

Encode just the SKU or asset ID. The QR code acts like a barcode—your software looks up the item by ID. Smallest QR code, most compatible.

TOOL-DRILL-001

Recommended: URL to Item Page

Encode a URL that opens the item in your inventory software. Anyone with a phone can scan and see item details, make updates, or log activity. Most flexible for multiple use cases.

Advanced: Structured Data

Encode multiple fields (SKU, location, batch, serial) in structured format. Useful for offline scenarios or when you need data without network access. Requires custom parsing.

{"sku":"DRILL-001","loc":"WH-A3","batch":"2024-03"}

Implementing QR Codes for Inventory

1

Decide What to Encode

For most inventory use cases, encode a URL to the item page in your software. This is flexible, works with any phone, and lets you update what the URL shows without changing labels.

2

Generate QR Codes

Use your inventory software's built-in generator, or free tools like QR Code Generator. For batch generation, export a list of URLs and use bulk generators.

3

Choose Label Size and Material

Minimum 1 inch (2.5 cm) for reliable phone scanning. Use synthetic labels for outdoor or harsh environments. Test scanning before printing large batches.

4

Print and Apply Labels

Print on Avery-compatible labels with a standard printer, or use a thermal label printer for higher volume. Apply to items, shelves, or equipment where scanning is convenient.

5

Train Your Team

Show staff how to scan with phone cameras or your inventory app. Define workflows: scan to check out equipment, scan to log service, scan to update quantity.

QR Code Best Practices

Use High Contrast

Black on white is most reliable. Avoid colored QR codes unless you test scanning thoroughly.

Add Human-Readable Text

Print the item name or ID below the QR code. Helps when codes are damaged or scanners unavailable.

Include Quiet Zone

Leave white space around the QR code (at least 4 modules). Crowded labels cause scanning failures.

Test Before Bulk Printing

Print a few test labels and scan with multiple phones. Check readability at expected distances.

Use URL Shorteners Carefully

Shorter URLs make smaller QR codes. But if the shortener service goes down, your codes break. Use your own domain when possible.

Protect Outdoor Labels

Use UV-resistant synthetic labels or laminate covers for outdoor equipment. Faded codes do not scan.

Generate QR Codes with StockZip

StockZip generates QR codes for every item and location. Scan with any phone to view details, update quantities, or log activity. No app download required.
