It’s perfect! Do you guys already do this?
I open a letter, I take it’s picture with FairScan. The FairScan-folder on my android device gets syncthinged to the ingest folder for Paperless-ngx on my “server”. Paperless imports it, deletes the file and sets the new documents tag to inbox. I decide if the document goes to the binder for important stuff, or if I just toss it in a binder with all the paper I most likely will never touch again. Next time I look at Paperless, I edit all documents with the inbox tag and remove the tag.
Most of those features are implemented in the scan software on the PC, not on the scanner itself. Although there is a tendency to integrate more and more features in the firmware, which is not always a good idea. Also, if you’re scanning low volumes, I’d say doing the separation before the scan is generally more efficient. At least that’s how I do it. But that’s just me, of course. I wasn’t in any way trying to criticize your approach. If it works for you, it’s great.
