🔢 Read and Parse GS1 (AI)

A focused demo that decodes GS1-formatted barcodes and parses Application Identifiers (AIs) to extract structured product and logistic data (GTIN, batch/lot, expiry, weight, serial, etc.). This folder contains two implementation styles so you can choose the integration that best fits your project.

Included files

  • scan-using-foundational-api/ — Foundational single-file implementation:
    • index.html — demo page.
    • index.css — styles used by the foundational demo.
    • read_and_parse_gs1.json — GS1 template file used by this implementation.

✨ Features

  • Decode GS1 barcodes (GS1-128 / EAN / GS1 Databar variants) from live camera or static image inputs.
  • Parse AI-tagged payloads into structured fields (GTIN, batch/lot, expiry, weight, serial, etc.).

🔧 How it works

  • The demos initialize the barcode scanner to decode GS1 payloads from camera frames or image files.
  • Decoded GS1 strings are parsed according to the provided JSON template (mapping AIs to labels and formats).

Quick start

Opening HTML files directly may not work as expected. Instead, run a local development server. Here's a quick method using Visual Studio Code:

  1. Install the Five Server extension from the VS Code Marketplace.

  2. Right-click on index.html and select "Open with Five Server".

💡 Tips

  • Use high-resolution images or increase camera resolution for small or dense GS1 fields.
  • Validate AI date/number formats (some AIs imply decimal places or YY/MM/YY formats).

📌 Notes

  • Serve the demos via localhost or HTTPS to allow camera access.
  • Replace the included trial/demo license with a valid Dynamsoft license for extended evaluation or production use.
  • See the repository root README.md for running instructions, licensing and API documentation links.
