It is a common practice in brazilian law offices to take pictures of case files, page by page. The procedure is required because the files can't be taken longer than five days, so it's more convenient to take pictures.
The pages in a case file are organized in a way that you can't simply take the pages and insert in a conventional scanner. They all have a couple of holes through which a metal string passes (very similar to a binder), which can be quite a burden to put back a few hundred old pages.
I've been doing some research to figure out the best way to take the pictures and so far I only have vague ideas concerning camera holders, page flippers and handheld scanners. Although this last seems like the best idea it's hard to find any information regarding how fast they are.
