It's a land of magic

In the US, Dartmouth College has developed Wanda, a device that can read wifi passwords and transfer this information to medical devices wirelessly. The Wanda prototype can acquire a network name and password by being plugged into a wifi router. To transfer the wifi data to the medical device Wanda is detached from the router and pointed at a medical device - because the medical device is close to the wand, it can reconstruct the information. However, a hacker further away could not.
