FDA approved pill turns your body into a password.

Motorola have shown off a pill which enables the user to transmit authentication passwords to a range of devices through their body, including phones, computers, cars or door locks.

The pill is powered by stomach acids, and according to the FDA it would be safe to swallow 30 of the pills every day for the rest of your life, although the pill lasts about two weeks before it “needs to be replaced”.
