Efficient and Accurate Barcode Data Extraction

barKoder’s GS1 parser is built to recognize and extract structured data from GS1-formatted barcodes used across supply chains, healthcare, retail, and logistics. It automatically decodes Application Identifiers (AIs) — turning raw barcode strings into clearly labeled, machine-usable fields.

Whether you're scanning product packaging, logistics labels, or healthcare identifiers, barKoder gives you the structured output you need in milliseconds.

What is GS1?

GS1 is the global standard for product identification and supply chain labeling. Its barcodes are used on over 1 billion products worldwide and encode data like:

  • Product identifiers (GTIN)
  • Expiry dates
  • Batch and lot numbers
  • Serial numbers
  • Quantity, weight, volume
  • Healthcare IDs (e.g., GSRN, GDTI)
  • Shipment and container data (SSCC, GLN)
