Syncfusion Blazor Barcode

Syncfusion Blazor Barcode Generator

Syncfusion's Blazor Barcode Generator package (Syncfusion.Blazor.BarcodeGenerator) provides three components for generating barcodes in Blazor applications:

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
