I use ScanPro all the time. I like it because , if I choose to, I can encrypt the document before I send it to the cloud.
My procedure is to send my documents to a Dropbox folder which happens to be an import folder for Evernote. When I invoke Evernote at the PC it automatically brings all my files in and then I tag them accordingly.
A side benifit is that all my notes are also remaining in the Dropbox folder. I never delete them and any important stuff is encrypted.
Works real good. I hope EN10 will allow import folders.
