Important Update
Barcode Reader SDK is created to assist both expert and entry-level developers to read barcodes from a live camera (C# – MVC). This Barcode Reader SDK also comes with an extensive library to simplify the process of common tasks of barcodes processing in ASP.NET.
Barcode Reader SDK is also loaded with state-of-the-art OCR and image recognition technology. Thus, it can be utilized in reading barcodes from images, scanned documents, and PDFs.
To enable you to utilize this Barcode Reader SDK without spending much time and energy in writing and testing codes, we provide you here with a sample code. All you got to do is copy and paste it into your ASP.NET project and let it do the barcode reading work for you. This ASP.NET code snippet is also available on our GitHub.
A downloadable FREE ByteScout trial version is available on our website. For your convenience, it also comes with programming tutorials to go along with source code samples.
