If the term “skin tag” grosses you out, you’re not alone, but the intestinally robust can now unlock their Moto X smartphone with a special sticker--an NFC-equipped skin tag--instead of a PIN or other tedious method.

A product of collaboration between VivaLnk Inc (with its eSkinTM technology) and Google’s ATAP division, you can now slap a sticker on your skin that will let you unlock your phone by touching it to the sticker. Call it a digital temporary tattoo.

Digital Tattoo

“The nickel-sized tattoo is adhesive, lasts for five days, and is made to stay on through showering, swimming, and vigorous activities like jogging. And it’s beautiful—with a shimmering, intricate design,” reads a Motorola blog post.

You can buy a 10-pack of the digital tats for $9.99, which seems a bit costly, but hey--it’s hard to put a price tag on a skin tag that unlocks your phone.

This is awesome. I currently use Cerberus and this would be a great addition to keep my phone secure. The downside is that the tattoo is temporary so this may want to be used only when you're going out for long periods of time like vacations where phones may get lost (or stolen). I wonder if it would work if someone made a permanent tattoo of the skin tag.


No no no. Dumb. Why would anybody want to do that? Is it really that hard to slide the screen that your finger is about to touch anyways? How is this helpful?


There was a ring that did this, but it is even more expensive. I think the concept is cool and I'd probably buy it for fun if it worked with the Nexus 4.


Say you have a password. This would just bypass it for you when you pick it up, assuming it can read through your hand if you put the sticker on the back of your hand.


I suppose, but I feel like apple has already done a better job of this with fingerprints. Seems like a more organic way to do it than having to apply a new sticker every few days.


Very true. I am not familiar with the way that sensor works. Do you have to rest your finger there for a couple of second, or does it unlock as soon as you press it/place your thumb there?


It just takes a second, there's a slight delay but not much. There's definitely still room for improvement in this area too, apple is far from perfect. I just don't understand the point of going this direction when better technology already exists. Patent conflicts perhaps.


You can also probably unlock it via the trash bag that your used ones are tossed into.


Uh, no thanks. This is taking security a bit far...


LOL guess these people ran out of ideas to rip you off.
