If you already have an electronic image of the barcode in tech phone/admin phone and want to decipher it as English text data, a barcode scanner might not be the best tool. Additionally, barcode scanners are limited to reading only 1-D barcodes which have restricted storage capacity, domain status, supported formats and can only be used with the Windows RT Class library. Nowadays, 2-D barcodes (also called QR codes) are more common and can store significantly more information like updated date.

A barcode scanning application can run on Windows, MacOS, or Linux without relying on any third-party tools or APIs since it is supported by .NET.

  4. If a recognizable code is found, the tool will decode the QR Code and display the resulting information.

The library is easy to use and can be integrated into web applications, mobile apps, and desktop applications.

ZXing has been widely adopted and has a large community of developers contributing to its development and providing support.

The library collects device information such as the device model and OS version, which can be considered a potential security risk.

Additionally, some have raised concerns over the ownership and control of the library, as it is not maintained by an independent organization.

Overall, ZXing is a powerful and versatile library for barcode generation and decoding, with widespread adoption and community support.

To generate a QR code using ZXing, for example, developers only need to write a few lines of code:

using ZXing;
using ZXing.QrCode;

// Create a BarcodeWriter instance to generate QR codes
BarcodeWriter writer = new BarcodeWriter
{
    Format = BarcodeFormat.QR_CODE // Set format to QR_CODE
};

// Generate a QR code with the text "Hello, ZXing!"
Bitmap qrCode = writer.Write("Hello, ZXing!");
using ZXing;
using ZXing.QrCode;

// Create a BarcodeWriter instance to generate QR codes
BarcodeWriter writer = new BarcodeWriter
{
    Format = BarcodeFormat.QR_CODE // Set format to QR_CODE
};

// Generate a QR code with the text "Hello, ZXing!"
Bitmap qrCode = writer.Write("Hello, ZXing!");
Imports ZXing
Imports ZXing.QrCode

' Create a BarcodeWriter instance to generate QR codes
Private writer As New BarcodeWriter With {.Format = BarcodeFormat.QR_CODE}

' Generate a QR code with the text "Hello, ZXing!"
Private qrCode As Bitmap = writer.Write("Hello, ZXing!")
$vbLabelText   $csharpLabel

To decode a QR code using the ZXing project, developers can use the following code:

using ZXing;
using ZXing.QrCode;

// Create a BarcodeReader instance for decoding QR codes
BarcodeReader reader = new BarcodeReader();

// Decode the QR code from a bitmap image
Result result = reader.Decode(qrCode);

// Extract the text from the decoded QR code
string text = result.Text;
using ZXing;
using ZXing.QrCode;

// Create a BarcodeReader instance for decoding QR codes
BarcodeReader reader = new BarcodeReader();

// Decode the QR code from a bitmap image
Result result = reader.Decode(qrCode);

// Extract the text from the decoded QR code
string text = result.Text;
Imports ZXing
Imports ZXing.QrCode

' Create a BarcodeReader instance for decoding QR codes
Private reader As New BarcodeReader()

' Decode the QR code from a bitmap image
Private result As Result = reader.Decode(qrCode)

' Extract the text from the decoded QR code
