Do they make portable scanners?

[AlphaDog]

I saw something like what you're talking about featured on one of the network news programs earlier this week, and the reporter who tried it out swears it works! I'm not sure I have a link to the right one, but it sounded familiar. The one they were demonstrating had a small hard drive in it that was able to store either data or photos. I know they were scanning a photo.

What you want does exist.
