We can develop our own barcode scanner app by using the IronBarcode library in C# or .NET Framework.

Introducing IronBarcode

IronBarcode is a powerful tool for working with barcodes and QR codes in C# and .NET applications. It is developed by Iron Software and is known for its accuracy, ease of use, and speed. Creating a barcode is simple, requiring just a few lines of code, and you can customize and resize it easily. Reading barcodes is also straightforward, supporting various sources like files and images. IronBarcode offers customization options for developers and supports a wide range of barcode formats, including QR codes with logos and conventional numerical barcodes.

Installing IronBarcode

To install the IronBarcode library using the Package Manager Console in Visual Studio, follow these steps:

Open Visual Studio and your project.
Go to the "View" menu and select "Other Windows," then choose "Package Manager Console."
To install the IronBarcode library, use the following command:

Install-Package BarCode

The Package Manager Console will download and install the IronBarcode library along with its dependencies. You'll see progress information in the console. You can start using its features for barcode reading and generating in your C# or .NET application.

Write code to Read Barcode

We will scan the following barcode.

The following code will read the Barcode from the given image and read the barcode value.

var barcodeResults = BarcodeReader.Read("barcode.jpeg");
 foreach (var barcodeData in barcodeResults)
 {
     Console.WriteLine(barcodeData);
 }

var barcodeResults = BarcodeReader.Read("barcode.jpeg");
 foreach (var barcodeData in barcodeResults)
 {
     Console.WriteLine(barcodeData);
 }

Dim barcodeResults = BarcodeReader.Read("barcode.jpeg")
 For Each barcodeData In barcodeResults
	 Console.WriteLine(barcodeData)
 Next barcodeData

VB C#

In the above C# code, a barcode image, "barcode.jpeg," is read using the BarcodeReader.Read() method from the IronBarcode library. The results are stored in the variable barcodeResults, and then, in a foreach loop, each barcode's data is iterated over and printed to the console using Console.WriteLine(). This code efficiently retrieves and displays the data contained in barcodes, allowing developers to integrate barcode reading functionality into their applications easily.

In this way, we can develop our own Barcode and QR code scanner app. IronBarcode also provides methods to create custom QR codes.

Conclusion

In summary, the Android ecosystem offers a diverse range of efficient barcode scanner apps, each with its unique strengths. Google Lens simplifies visual searches, while Essential Labs' Barcode Scanner - Price Finder focuses on price comparison. Gamma Play's QR and barcode Scanner stands out for its dual functionality and additional features. TeaCapps' QR & Barcode Reader prioritizes security and versatility, and QR Easy's app streamlines everyday tasks.
