I don't have or use a card scanner, I just don't have need of one I suppose BUT I was reminded of my very first project as a Virtual Assistant - my client had copied over 200 business cards onto single sheets, so there were about ten cards on each sheet. She then faxed me each sheet and I manually entered all of the information from each card into an XL sheet.... had I had more information at the time I would have advised her to invest my hourly rate in a card scanner and do it herself simply for all the time it took to get that task done.
I'm curious too about what brands people are using - or is no one else using a card scanner in their business??
