Comic book scanning

So I am not a developer. I am a reseller that sells in comic, toys and cards.

I love using the app to scan over my inventory but I only use if for cards. Can this technology be implemented into the world of comics? I suspect it will not be super difficult as there are already sites with huge databases like comicspriceguide.com and GoCollect.

If it is already implemented and I just do not know about it I would love to know.
