A Digital Tattoo is the simplest way to unlock your phone.

The discreet, elegant device is simply worn on your wrist, about the size of a nickel.

Apply it and just be yourself. It will stick with you. Your Digital Tattoo will hold through showers, swimming, and just about anything you throw at it.

One tap of the Digital Tattoo and your phone is unlocked, no finger swipes, no pin codes.

A Digital Tattoo kit includes 10 tattoos—about a month’s supply. Each will sync to your Moto X’s NFC unlock.


VivaLnk’s breakthrough technology has made it possible for us to create thin, flexible electronics that are adhesive, inexpensive, and disposable, and can communicate with smartphones and tablets.

We envision a future where our technology has been adapted to countless applications, including thousands of yet-to-be-imagined uses in the hands of people around the world.
