Over the years, I've worked with a few business card scanners, and while these usually include support for Outlook, Goldmine, Act!, and a number of other PIMs, Lotus Notes support is often weak, and usually limited to basic address fields in the personal address book. I did a cursory search a year ago and found that someone had written an import tool. Ideally, I'm looking for seamless integration - without having to write it myself. I'm sure I'm not alone in this quest.
If you are presently using a business card scanner with Lotus Notes, I hope you will take a few minutes to share your experience or, better yet, blog about it and send me the link so that I can refer folks to your blog.
