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

For consumers exasperated with keying in passwords each time they want to access their smartphone, help is at hand: Motorola has invented something that looks like a nicotine patch, which it calls a tattoo, and which can unlock a phone with the flick of a wrist.

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.
