QR Codes for Inventory Management: Labelling, Scanning Workflows, and Asset Tracking

1. Why QR for Inventory

A QR code can store a unique item ID, location, and batch reference in a single symbol. Most staff smartphones can scan without a dedicated device, lowering hardware costs.

2. Label Design

Print the item ID in human-readable text alongside the code. Use level Q, 0.5 mm minimum module size, and durable polyester or synthetic labels in environments with moisture or chemicals.

3. Scanning Workflow

1. Receive: scan item QR into the system as "in stock" at a specific location. 2. Pick: scan to decrement stock and record who moved it. 3. Ship: scan for outbound confirmation. 4. Count: periodic scan to reconcile actual with system stock.

4. Unique Code Per Item vs Per SKU

Serialised codes (one per unit) enable precise tracking but cost more to print and manage. SKU-level codes are simpler but cannot track individual items.

5. System Integration

Expose a simple POST endpoint or use a spreadsheet-backed webhook. Keep the mapping of QR payload to item description in a database you control.
