What Ive learned about laptop scanners
Portable scanners create digital records from business cards scanned by optical character recognition technology. Optical character recognition technology enables the portable scanner to extract images and text from a business card and sort the information into the appropriate template in your contacts database. You simply feed the card into the portable scanner, which reads and stores the information into your laptop computer with your other digital contacts via USB cable. This is all accomplished without need of an external power source or additional software. Scanning new contacts into your laptop with a portable scanner is so much easier when you are on a sales trip or attending a trade show.
