Syncfusion Blazor Barcode Generator

Syncfusion's Blazor Barcode Generator package (

Syncfusion.Blazor.BarcodeGenerator

) provides three components for generating barcodes in Blazor applications:

Component	Use For
`SfBarcodeGenerator`	1D linear barcodes (Code39, Code128, Codabar, etc.)
`SfQRCodeGenerator`	QR codes with optional logo embedding
`SfDataMatrixGenerator`	2D Data Matrix codes for compact encoding

All three work in Blazor Server, Blazor WebAssembly, and Blazor Web App (.NET 8+).

When to Use This Skill

User needs to render or display a barcode in a Blazor component
User asks about QR code generation (e.g., product links, 2FA, contact cards)
User needs Data Matrix codes (pharmaceutical, logistics, label printing)

User is configuring

SfBarcodeGenerator

,

SfQRCodeGenerator

, or

SfDataMatrixGenerator

User asks about exporting a barcode as an image (JPG/PNG) or Base64
User asks about barcode types, error correction, checksums, or validation events
User is embedding a logo in a QR code

<SfQRCodeGenerator Width="200px" Height="200px"
                   Value="https://www.syncfusion.com">
</SfQRCodeGenerator>

Data Matrix

razor

@using Syncfusion.Blazor.BarcodeGenerator

<SfDataMatrixGenerator Width="200" Height="150"
                       Value="SYNCFUSION">
</SfDataMatrixGenerator>
