Hi, It is possible to have a component that enables the use of the camera and to be able to scan barcodes or QR (1D & 2D), for Blazor Web assembly and Blazor Server Side. Now this require JavaScript library like as QuaggaJS.
I think that having such a component is very useful and will allow you to build applications with advanced functionalities, other companies offer but only to generate barcodes or QR codes.
Example thanks aLorsSilvermort : https://github.com/LorsSilvermort/BlazorBarcodeReader
Best Rgards,
