The Moto X is getting more interesting, Motorola is cooperating with Vivalnk to give you a digital temporary tattoo that can be printed on your hand, to be your unique identifier used to unlock your Moto X smartphone !
The Tattoo works with NFC connectivity to communicate with the phone, and when your Moto X is near your hand, you can unlock it by a simple tap on the Tattoo !
The digital Tattoo lasts only for few days and it disappears due to your daily activities (shower, exercises...).
You can get the Tattoo for just $1 and if you want to use it for a longer period, you can buy 10 of them for $10.
If you want to show off in front of your friends and use it, get it from Vivalnk here.
