For me, a portable scanner has become invaluable!! I have an Epson DS-635 that plugs directly into my “Utility” laptop, no security problems. I use it at every signing to scan signer’s ID. It is used for the docs only occasionally, as mentioned above, if time is a factor and the package is manageable. More times than not the signers are more than willing to let 15-25 pages get scanned so the packet can ship in a timely fashion, mostly because they have skin in the game. McDonald’s and Starbucks are likely candidates otherwise. The Brother DS-635 is $100 at Wal-Mart and the software is easy and user friendly. Most cell carriers have a Mobile Hotspot option, so doing the scanbacks in a public setting or at a signers home, and is pretty darn secure, I don’t use it long enough to worry. The way I see it, having great tools in the toolbox only makes you a more valuable asset.
