Unfortunately, all brand name scanners have a microchip device built in which recognizes all global currency notes in use. The only way of keeping your existing scanner (without forking out $) is to use an older model laptop (ie. 2 years old or so) that runs on Windows XP, or older version, where they have a USB Port. That way, you can continue to enjoy your use of your scanner, scan the images using your existing HP scanner, and then transfer the photos/images to your new computer via a USB memory stick.
