Barcodes, the Bedrock of Traceability

 In Barcode Quality Training

Barcodes are the bedrock of traceability.

Without barcodes, traceability is impossible.  Barcodes identify products, assets, and shipments in a supply chain Here’s how barcodes contribute to traceability:

  1. Unique Identification: A unique barcode is assigned to each product or item in a supply chain. Encoded data contains information such as the product type, batch or lot number, and expiration date. This uniqueness enables accurate tracking of individual items throughout their journey in the supply chain.
  2. Data Capture: Barcode scanners at various points in the supply chain update the system about the item’s location, movement, and status.
  3. Accuracy and Efficiency: Compared to manual data entry, barcode scanning is fast and accurate. This ensures that data regarding inventory levels, shipments, and product movements is instantly available and reliable–crucial for effective traceability.
  4. Integration with Systems: Barcodes easily integrate into existing digital systems such as ERP (Enterprise Resource Planning) and WMS (Warehouse Management Systems). This provides seamless, error-free data sharing and visibility across the supply chain network.
  5. Compliance and Regulations: Industries with strict regulatory requirements, such as food and pharmaceuticals, mandate barcodes for traceability. Barcodes ensure compliance with product safety, recalls, and authenticity.
  6. Counterfeit Detection and Prevention: Tracking movement through a supply chain continuously confirms the presence of the shipment and its match to the Advanced Shipment Notification (ASN). If an item bearing a duplicate barcode appears somewhere in the supply chain, it will be immediately detected.
  7. Traceability and Recall Management: In the event of a product recall or quality issue, barcodes rapidly identify and locate affected products. This mitigates risks and minimizes the impact on consumers and the supply chain.

Barcodes or RFID?

RFID is another important tool in traceability. RFID tags and readers fundamentally do the same thing that barcodes and scanners do, but each technology has different abilities.

RFID propagates a blast of radio energy covering a defined area. For example, RFID antennae at a dock door can read multiple tags on palletized products as they enter or leave. This can include  tags on products buried inside master cartons. It is difficult to find a particular item in a room full of RFID-tagged items: you know it is there, but where exactly?

Barcodes require line-of-sight scanning. You can easily scan an individual item by aiming the scanner but every item must be scanned individually.

Both technologies have advantages and disadvantages but more importantly, they work well together.

The role of barcodes in traceability underscores the importance of barcode quality and compliance.
