• Unique Identification: This section will delve deeper into the specifics of assigning unique identifiers. It will cover the advantages and disadvantages of various techniques:

  • Barcodes (1D & 2D): Discussion of different barcode symbologies (e.g., EAN, UPC, QR codes), their limitations (read range, data capacity), and applications within production facilities.
  • Radio-Frequency Identification (RFID): Detailed explanation of active and passive RFID tags, their read ranges, data storage capabilities, and suitability for different environments. Comparison to barcodes.
  • Serial Numbers: The use of alphanumeric serial numbers for individual item tracking, particularly valuable for high-value or low-volume goods. Methods for generating and managing serial numbers.
  • DNA Tagging: Emerging technologies utilizing DNA markers for unique identification, highlighting their potential and current limitations.

• Data Collection Methods: This section outlines the different ways data is captured throughout the production process:

  • Manual Data Entry: Discusses the challenges, error rates, and its suitability for only small-scale operations.
  • Automated Data Capture (ADC): Covers the use of scanners (barcode, RFID), sensors, and machine vision systems for automated data collection, improving accuracy and efficiency.
  • Real-time Data Acquisition: Explores the benefits of instantaneous data capture and its role in process monitoring and immediate feedback loops.

• Data Encoding & Embedding: Focuses on methods to encode and embed traceable information directly into the product or its packaging:

  • Data Matrix Codes: Discusses their high data density and resistance to damage.
