One of my friends recently asked for advice on going paperless, so I thought I'd share the techniques and tools that I've been using for the past few years.

I try to scan all of the paper I get (receipts, mail, etc...) and convert it to a searchable PDF using the Fujitsu ScanSnap S510M:

I think I bought it in 2007, and have been very pleased with it.

Once I've scanned it, I shred it using this shredder:

The nice thing about it is that it automatically shuts off when it detects a hand/fingers, which is especially nice because we have little kids in the house.

Soon DOKUMENTS will have a desktop app that will automatically upload files (like scanned documents) to your DOKUMENTS account, making it easy to organize and share them.

If you've got any tips or suggestions, please let me know!
