Install a pdf/doc scanning type app, like office lens, from Microsoft on your phone.
Point phone at a document takes a photo from within the app.
You don’t need a dedicated app, you could use the camera app but then you’d have jpegs etc .. Instead of a dot pdf.
Even if you have a lower end phone with a poorer camera, it will still make an excellent scanner, just make sure the room/document is decently lit. Even the cheapest phones are 8mp, so will make a good shooter of docs and receipts.
I’ve seen someone once, set up their phone on a homemade a tripod, facing down, so you can switch in out docs and scan real fast. Probably worth it if you’re scanning a big backlog.
The good thing about office lens is it cute off all the leftover space, and make a “quick and clean” copy all in focus and in the frame.
It’s a good app. I don’t think I’ve used my current scanner (on my printer ) since I got it. Which would be over a year.
