I have been searching Apple Store for a business card scanner specifically for the Ipad 2. They don’t have one (at least i couldn't find one). But they do have infinite police scanners, alien scanners, vampire scanners, paranormal scanners, fart scanners and even a poop scanner. Yes an an App that will tell you what kind of bowel motion you will have....go figure.
I have seen some that are for the iphone so can any one suggest which would be the best option to buy?:
ScanBizCards, CamCard, Business Card Reader, WorldCard Mobile

I just got out a business card and took a snapshot of it with the iPad's camera. Even in a low-light setting, it worked perfectly. That might be a kludge of a way to capture a business card, but it works perfectly, and without any cords, expensive external equipment, apps, or annoyances.

Come to think of it, perhaps I have been mislead by your use of the term "scanner" which I had originally taken to mean a device to use for scanning. That might have been because I just got back from a ￿Staples, and was looking at flatbed scanners and bar-type scanners. If you're looking for software - well, other than my above suggestions... nevermind.

i also would like an app that could transfer those data directly to my contacts list... i haven't found any yet for my ipad2, only for the iphone.

There is a program call ScanBizCards, you may want to do a google search and read reviews.

I use Iphone to hold business cards now. Excellence!
