It seems that you have so many devices on your computer table and you're not able to find space for you newly brought scanner then go for this keyboard which is integrated with a scanner in it. The keyboard is a USB keyboard. But one problem with this is that when you need a book to be scanned it doesn't serve your purpose, it is just a sheet scanner.
