not sure if this is really real
or just a really good mashup 
either way it's a good read, and begs the question: Would you ?
Passwords: They’re everywhere, and most of us manage a half-dozen or so, at least. They’re also the weakest link in the authentication chain because humans aren’t great at creating passwords remembering them.
A Motorola executive (and former Defense Advanced Research Projects Agency head) Regina Dugan proposed a solution at the D11 conference: pills and tattoos.

“Authentication is irritating,” she said at the conference. “So irritating that only about half the people do it even though there’s a lot of information about you on your smart phone.”
One idea Motorola presented was the “vitamin authentication” pill. One of Dugan’s colleagues showed a small tablet that contains an electronic chip. After someone swallows the pill, stomach acts as an electrolyte in the chip’s battery and powers it.
The chip has a switch that turns on and off, generating an 18-bit signal like an electrocardiogram. Ones entire body would be the authentication token, just like the fobs that many office workers carry to get on corporate networks. The authentication could be activated by touch, since the human body conducts electricity — touch your phone or laptop and you’re in.
Ingestible sensors have been FDA-approved — a company called Proteus Digital Health makes the technology for medical applications, such as recording exactly when medicine is taken.
For Motorola, the question is whether the pill or a similar innovation — an electronic tattoo, which Dugan wore during the conference — can be adapted to other applications. (There isn’t currently any collaboration between Motorola and Proteus).
