Scanning artwork, hand-written papers, documents, and photos can come in handy when communicating with instructors and others. There is no need to purchase a scanner, because you can use an app on your phone.
We have tested CamScanner and found it to be user-friendly. If you can take a photo with your phone (android or iPhone) or iPad, you can scan a document and send it as a PDF. There are plenty of posts on Youtube if you want to see how CamScanner works.
