Motorola smartphone users can unlock devices with stick-on RFID tattoo

The "eSkin" tattoo sticks to the users’ skin - the optimum location being on the inner wrist - and will stay in place for five days, able to withstand water and sweat. To unlock their phone, users need only hold their device up against the tattoo, et voila.

Motorola has produced a video explaining how it works.
