Motorola has partnered with VivaLnk to create a temporary phone unlocking tattoo. No pin, no password, just a touch of the device on your skin and voila! Instant phone access.
Affordably priced at ten dollars per pack (of ten), the tattoos have the ability to withstand the elements. That means you can shower, swim and sweat as you normally do, without fear of your tattoo rubbing or wearing off. Optimally, the ten-pack will last a little over a month and a half, meaning you'll have to ask yourself if the extra ease is worth the prolonged look of the tattoo on your skin.
Currently, the tattoos only work with the Motorola X. But who knows, perhaps the company will expand its availability to include other Androids in the future. Until that day, you're unfortunately going to have to unlock your phone the old-fashioned way.
