Motorola has released a tattoo that unlocks your phone

Let’s face it, when companies are interviewed at tech conferences, they talk about all kinds of crazy stuff that will never be launched, like the idea of wearing a digital tattoo to unlock your phone. Except this time, more than a year after first discussing the idea at the D11 conference last May, Motorola has actually done it and is showing it off in a new video. VivaLnk is selling packs of Digital Tattoos for a dollar each. Currently available for the Moto X, with support for other phones promised, each tattoo is said to last for around five days before washing off.
