Last week, we developed a RESTful service using .NET C# and Twain.Wia.Sane.Scanner library to scan documents from TWAIN, WIA, SANE, and eSCL scanners. This week, we will repurpose the C# code to construct a Blazor WebAssembly application that digitizes documents directly from a web browser, all without the need for...

When developing or selecting an MRZ (Machine Readable Zone) recognition SDK, the primary challenge lies in finding an appropriate dataset for testing. Acquiring genuine MRZ images is challenging, and due to privacy concerns, they aren’t publicly accessible. Therefore, crafting MRZ images becomes a practical solution. Fortunately, there’s an open-source Python...
