#2 Smartphone as a Scanner App!
Convert your phone into a scanner. I use it for student submissions of handwritten or signed documents. For example, consent forms for research participants.
Handyscanner
Handy Scanner Free turns your phone or tablet into a powerful document scanner. Say goodbye the piles of paper that follow you around. You can scan multipage documents, whiteboards, business cards and so much more. The post-processing filters give you the greatest quality with the lowest background noise. Then, just share them to GMail, Dropbox or any other application. Better yet, use instant uploading to Dropbox! Produces both PDF and JPEG images!
