Business Card Scanning-How can I use a regular scanner with special software to scan business cards?

Business Card Scanning – Does anyone know to use use a regular scanner with special software to scan business cards? I don’t understand why I need to buy yet another scanner just for business cards.
Obviously, I need to clarify my question. Business cards need to be scanned to be imported into Outlook or other PIMs.

Couple for you to try here, haven’t tried any as i have a business card scanner (hardware + software package)
