How to scan a barcode

1. Open the scanner page on a supported browser.
2. Choose Start Camera or upload a clear barcode image.
3. Keep the complete barcode visible, focused and well lit.
4. Review the decoded result. The scanner does not automatically open links.

Barcode formats and limitations

Supported formats depend on the browser's native Barcode Detection API or the available decoder fallback. Common formats may include Code 128, Code 39, EAN, UPC, ITF, Codabar, Data Matrix, PDF417 and Aztec. Not every device or image will support every format.

Safety and quality checks

• Use a sharp image with the entire barcode visible.
• Check decoded product numbers or URLs against a trusted source.
• Do not assume a barcode proves that a product is genuine.
• Do not open unknown links or share private data from a scanned code.

Frequently asked questions

Does scanning automatically open a link?

No. The result is displayed first so you can inspect it before taking action.

Will it read every barcode?

No. Results depend on format support, image quality, focus, lighting and the barcode condition.
