Dynamsoft's Barcode Reader SDK
What's slick about Dynamsoft's Barcode Reader SDK is that just a few lines of code from scratch are required instead of potentially hundreds of them, which could save months of development time. The updated Barcode Reader SDK 4.2, which adds Linux PHP support, allows application developers to embed functionality for decoding linear and 2D barcodes into Web or desktop applications almost instantly, significantly reducing development costs and costs of long-term application support.
Barcode recognition is enabled from image files, scanned images and from images captured on Webcams or smartphones. The new PHP barcode reader toolkit for Linux supports PHP x64 versions 5.3–5.6. Both Thread Safe and Non Thread Safe options are provided. The Dynamsoft toolkit works with Debian, Ubuntu and CentOS. Support for Web applications in ASP.NET, in C# or VB.NET, and PHP on Windows also is included, just in case.
