Online Barcode Scanner Using Mobile Camera
If you need to enable online barcode scanning from a live camera stream, this web application demonstrates how to scan barcodes using mobile cameras and webcams.
The application is built using Dynamsoft Barcode Reader SDK JavaScript Edition. The web SDK supports real-time localization and decoding of various barcode types. The advantages:
- As the decoding happens at the client side, there is no need to upload video frames to the server side, so the decoding is much more efficient.
- The solution is pure browser-based. And no installation is required at the client side. One single application can support barcode reading in different browsers both on mobile and PCs.

- 1D barcodes: Code 39, Code 93, Code 128, Codabar, Interleaved 2 of 5, EAN-8, EAN-13, UPC-A, UPC-E, Industrial 2 of 5, MSI Code
