Online barcode recognition demo

This demo application is designed as an online barcode recognition web application where you can open your own documents and read several barcode symbologies from them.

Try demo

When a barcode is found, a semi-transparent text annotation will be added over the detected barcode with its symbology and its value.

Recognized symbologies include QR code, Micro QR code, PDF417, DataMatrix, Aztec, Code 39, Codabar, Code 128, Code 93, EAN 8, EAN 13, Patch Code, and UPC Version A and E. For the exhaustive list, refer to the GdPicture.NET barcode SDK documentation(opens in a new tab).

This demo application also demonstrates how to build and use a custom snap-in. It’s a UI/UX component where you can add your own content and business logic. This demo uses it to list the available symbologies to detect.
