"I take a vitamin every morning, what if I could take vitamin authentication?" Dugan asked, shortly before pulling such a pill out of her pocket.
"This pill has a small chip inside of it with a switch," she said. "It also has what amounts to an inside-out potato battery. When you swallow it, the acids in your stomach serve as the electrolyte and power it up, and the switch goes on and off. It creates an 18-bit ECG like signal in your body so essentially your entire body becomes your authentication token."
"It means my arms are like wires and my hands are like alligator clips [so] when I touch my phone, my computer, my door, I'm authenticated."
