What Ive learned about portable scanners
All you have to do is feed the card into your portable scanner, and the scanner reads and stores the card information on your laptop through a connected 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. Trade show exhibitors find portable scanners ideal for compiling and maintaining leads from the many business cards that they receive in the course of their business. Small business owners and freelancers like portable scanners for their simplicity.
