Using the human body as a wire-like communication channel.

Guest Dr. Shreyas Sen, a Perdue University associate professor of electrical and computer engineering, joins us to discuss the following scenario:. Instead of inserting a card or scanning a smartphone to make a payment, what if you could simply touch the machine with your finger? A prototype developed by Purdue University engineers would essentially let your body act as the link between your card or smartphone and the reader or scanner, making it possible for you to transmit information just by touching a surface.
