Amazon sells portable scanners for laptops. I can't tell you if it's worth buying the scanner as I'm not sure what you are looking to do with it. A portable scanner will not give you the quality that a larger scanner can give you, but if you're just scanning receipts or black and white documents then it's an option. I've seen then costing around $50, but for that price I've also seen full-sized scanner/copier/printers; so it really depends on what you'll be using it for.
