A huge bunch of stuff on document scanner
You could scan hundreds of business cards per hour with a business card scanner. Some scanning products have the ability to backup your contact information online. Others have the capability to share your contacts with the other members of your computer network, so everyone is working with the same information. Sharing can be accomplished by plugging and unplugging the USB cable and port from one computer to another. You can also share by installing the card database into a shared network.
