Smart phone scanning apps are incredible. I’ve ditched a flatbed years ago and solely rely on my iPhone. It works like magic. The quality is good-to-great, and it fits well with my workflow. Worth the ten bucks or so investment.
Don't even need to spend $10 — the scanning is built into iOS, you can get to it from the Files or the Notes app, or even from your Mac (right-click somewhere and "Import from iPhone or iPad").
