Last week, Fujitsu added an awesome feature to their ScanSnap scanner line (at least, the iX500 that I have). You can set it up so that, rather than having to have a machine on the same wireless network to pick up the scanned documents, the scanned documents just get shipped to your Dropbox or Google Cloud.
That let’s you do some really interesting things. You can run Hazel rules on your Dropbox folder, just like you can on a local folder, to do automatic sorting, naming, etc. on your machine. You can also do some interesting automation things with IFTTT to trigger other types of activity based off of files getting scanned. Or some combination of both (you scan some sort of receipt, it’s automatically filed into a folder via Hazel, which also triggers an IFTTT action to send an email to someone telling them that receipt is there).
The cloud feature seems small, but it’s a huge improvement to the convenience of what is already a device that has made my life a lot simpler.
