Automatic Code Inspection on Labels – A Revolution in Warehousing

Vision systems capable of reading 1D and 2D codes (QR, Datamatrix) and text (OCR) support warehouse processes by enabling automatic tracking (track & trace) of products.

In today’s rapidly evolving world of logistics and warehousing, technology plays a crucial role in streamlining operational processes. One of the latest advancements in this field is the system of automatic code inspection on labels, which are affixed to packages placed on pallets. This innovative system, integrated with automated production and warehousing lines, offers numerous benefits, from increased efficiency to improved accuracy in product verification.

How Does the Code Inspection System Work?

The code inspection system is based on advanced image acquisition and analysis technology. Labels containing barcodes, QR codes, or text with key information (OCR) are affixed to boxes, which are then placed on pallets. The entire inspection process is fully automated, so the boxes are inspected during the standard pallet wrapping process on the wrapping machine.

Main Functions of the System:

  • Automatic Label Inspection: High-resolution cameras analyze labels, identifying any irregularities such as unreadable codes or incorrect information.
  • Code Verification: The system meticulously checks barcodes and QR codes, ensuring they match the data in the warehouse management system (WMS).
  • Reporting and Tracking: Any errors and irregularities are immediately reported to operators, allowing for quick correction. The system also generates detailed tracking reports, which are crucial for ensuring compliance with quality standards.

Benefits of Using the Code Inspection System

  1. Increased Efficiency
    • By automating the inspection process, warehouse workers can focus on more complex tasks, leading to overall operational efficiency.
  2. Improved Accuracy
    • Automatic code inspection eliminates the risk of human error, which is crucial for ensuring high-quality service and minimizing costs associated with claims
  3. Time and Cost Savings
    • The system allows for faster processing of large volumes of shipments, significantly reducing the time needed for inspection and associated operational costs.
  4. Better Quality Control
    • Code verification systems ensure that all products are correctly labeled, which is essential for maintaining compliance with industry standards and regulations.


The code inspection system finds wide application across various industries, including

  • Logistics and Warehousing: Automating code inspection processes improves the efficiency and accuracy of inventory management.
  • Manufacturing: Code verification at the production stage ensures that products reach the correct recipients with accurate labeling.
  • Distribution: These systems are crucial for distribution companies where fast and accurate shipment processing is essential.
