Microsoft has another new tool I would like to share this week, Office Lens.
According to the website "Office Lens is the new camera built into OneNote for iPad or iPhone that lets you take pictures of whiteboards or printed documents, then enhances your photo by cropping, sharpening, and straightening it, so it looks almost like a scanned image. Your picture is added to your note so you can retrieve it later."
From within OneNote you can use Office Lens by following the simple instructions here
Office Lens is also available as a stand alone PDF scanning app for Android and iOS.
