I am trying to scan ITF(2 of 5) / Code-2of5 Interleaved barcode using emdk for Xamarin but which not working in my application.
I believe the issue is something related to my configuration. But not sure what went wrong in my code. Please find the source code I am using for your reference.
# I am attaching the barcode which I am trying to scan for your reference.
# Also Please find the Full sample app, That may help you to debug.
Link to download the sample app.
