If you have a camera that has an HDMI or other video output they basically convert it to a USB camera.
I have an action cam (like a knockoff gopro) that has a pretty good image. So I could use that as a Webcam if I had one of those capture cards?
Also, I forgot to mention: It doesn’t have to read all the text on a card, it just needs to be able to accurately detect which card it is, then Spelltable pulls up the card text from a database.
