OCR with Xamarin

Question

I would like to read info from an ID card using OCR in my Xamarin Forms app, but the only example I find is this and it's pretty outdated (or I just don't know how to use it).

I also saw the Google Vision AI, which I could use in my Xamarin.Android (or iOS) and pass the information to my shared project, but I can't imagine how I would do that.

Is there anyone who could help me with this?

Answer 1

There is a Xamarin wrapper for Google's Teseract you could use: https://github.com/halkar/Tesseract.Xamarin

var client = new VisionServiceClient("{YOUR-API-KEY-HERE}");

    text = await client.RecognizeTextAsync(photoStream);
