I work to be as paperless as possible in business and for my personal documents. To do this, I scan anything that is paper in and shred everything possible. All documents are backed up in the cloud using real time sync with encryption.
The ScanSnap can scan up to 50 pages at once at a speed of 25 two sided pages a minute. The ScanSnap is able to scan both sides of a page in one pass without any loss in speed.
All documents are immediately OCR (optical character recognition) so they can be searched. This entire process is automated end to end, all I need to do is to put what I want scanned in the scanner and hit a button.
This scanner is fast, and extremely reliable. I probably have done a few thousand pages through mine over the years. I have an older model of this scanner I've been using since 2010!
I love this thing! It isn't cheap though, and unless you have a business it is hard to justify the high cost but it has lasted me over 8 years with daily use.
The ScanSnap goes for $419 shipped from Amazon with free two day shipping.
