Barcode Knowledge & Tips

  • What is a Barcode? A barcode is a machine-readable representation of data, typically used to identify products, assets, or documents.
  • 1D vs 2D: This tool generates 1D barcodes (linear), not 2D codes like QR codes.
  • Choosing a Format: Use CODE128 for general purposes, UPC/EAN for retail, and ITF for numeric-only data.
  • Contrast & Size: Ensure high contrast and adequate size for reliable scanning.
  • Human-Readable Text: Always include the encoded data in text form below the barcode for manual entry if needed.
  • Testing: Test your barcode with multiple scanners and devices before final use.
  • Legal Compliance: For retail, ensure your barcodes meet industry standards (e.g., GS1 for UPC/EAN).
  • Printing: Use high-quality printers and materials to avoid scanning errors.
  • Security: Barcodes are not encrypted; do not encode sensitive information.

Understanding barcode basics helps you avoid common pitfalls and ensures your codes work reliably in any application.
