hey, this is a great idea! I'll link into your app from my readme. I really like that the PDF contains the entire dataset, not just the keys. I see lots of little details around organizing the PDFs, like document hashes, etc, very nice job!

Since you wrote it in Rust, I'd suggest compiling it to wasm and releasing a browser-based version

That was my eventual plan for having a single GUI for everything, the only problem is that there isn't a really obvious way to support scanning a PDF you upload -- basically you need a pure-Rust PDF renderer and there isn't one up to the task as far as I could tell. On mobile you could scan each QR code separately (though doing this from a webapp is probably going to be a fairly awful UX and most people would prefer to photograph the whole document and get everything scanned automatically).

use the webcam, you put the QR in front of the webcam, there has to be a library for this

Actually, after my comment I took another look and it turns out that only a few months ago someone released a pure-Rust PDF renderer called hayro[1] that seems to fit exactly what I need, so I will work on finishing this bit of paperback as soon as I have some spare time. Pure image scanning (with a webcam, phone camera, or uploading a photo) will also work since QR code scanning libraries like rqrr support scanning all QR codes in an image.
