If you are looking for a wireless scanner, the PocketScan by Dacuda is the smallest of its kind. Currently being crowdfunded as a Kickstarter campaign, the handheld scanning device is barely bigger than a business card and is compatible with your Mac, PC or iPad.
With this wireless scanner you can scan things that wouldn't fit in a traditional scanner, including large pieces of artwork and menus written in a foreign language, simply by tracing the PocketScan over the desired area. You also receive instant feedback, as the image or text will appear right away, even opening new notes in Evernote or documents Microsoft Word.
The mobile scanner is ideal for translating text when travelling, copying down family memories as well as more efficient work and study.
