scanR is a free service that transforms phonecam photos of documents, business cards, or whiteboards into cleaned-up PDFs that it will then fax or email on your behalf.
Documents are placed through an OCR process, so the text is selectable and searchable (though I’d probably rather have my documents converted to plain text or html). For whiteboards, you don’t even need to take the shot head on. The software will take cues from the whiteboard’s edge to transform the image into proper alignment.
Save a trip to the fax machine, and never write “Do Not Erase” again -Link.
