After a little bit of a false start yesterday, Motorola has officially announced Skip, its thumb-sized NFC clip that'll let you unlock your Moto X quickly and easily. Tap your phone to it, and it unlocks. (Of course, your thumb can do that, too, and not cost $20.)
But along with each skip purchase you'll get three "Skip dots," which Motorola says will create a "Trusted Zone" for your Moto X, allowing it to stay unlocked while it's within range. So put one in your car, and you won't have to unlock the phone, for instance.
If you snag a custom Moto X through Moto Maker, you'll get a free Skip (and the Skip Dots, we presume) with your phone. For now, you can have it in any color you want, so long as it's gray. More colors care coming this fall.
