Let’s develop a JPG QR Code reader module for a business application to automate QR Code detection and reading. This automation will give your application a competitive edge in terms of productivity. In addition, this blog post will introduce a web-based online barcode scanner to scan barcodes online. Aspose.BarCode provides barcode scanner APIs in multiple programming languages. However, in this guide, we will build a C# barcode scanner using Aspose.BarCode for .NET. This .NET library makes the whole process pretty smooth and lightweight. So, let’s move forward without stating any word further.
We will cover the following points in this article:

Build a JPG QR Code Reader in C#
Now, we will use the classes and methods exposed by this barcode reader API to build a JPG QR Code reader in a .NET application. Please be aware that we have a source JPG file containing a barcode and a QR code.
You can follow the following steps:
- Initialize a new instance of the BarCodeReader class with the source file.
- Read the barcode from the image by calling the ReadBarCodes method and assign it to an instance of the BarCodeResult class to store recognized barcode data from the image.
- Invoke the CodeText property to get the code text.
- Get the barcode type by calling the CodeType property.
- The Confidence property is used to get the recognition confidence level of the recognized barcode.
- The Region property is used to get the barcode region.
Copy & paste the following code sample to programmatically develop a C# barcode scanner for your application:
Once you run the above code snippet, you will see the output in your terminal/CMD as you can see the output of our source file shown in the image below:
