Researchers at the MIT Media Lab have developed an application called Sparsh that allows users to store data using their bodies (metaphorically speaking).

Sparsh lets you touch a data item to copy data from a smartphone, tablet, or laptop, using Dropbox or an FTP account to temporarily “store” it, and then touch a second device and paste the saved content. (The actual data transfer happens in the cloud.)
