It’s another step in making it easier to unlock your phone on the go and keep your personal information safe. An average user takes 2.3 seconds to unlock their phone and does this about 39 times a day—a process that some people find so inconvenient that they do not lock their phones at all. Using NFC technology, digital tattoos make it faster to safely unlock your phone anywhere without having to enter a password.
My opinion on “wearable tech” (that’s what this is, right?) is that it needs to be a) unobtrusive and b) add value to the user experience. For something that’s going to a) require extra management of a physical object that can grant access to your smartphone and b) cost the end user an estimated extra $80 a year for the privilege, I think this is the wrong answer to the wrong question.
The technology is cool (although just as susceptible to hacking as anything else), it’s a novelty at best, but I think I’ll stick to using my thumb.
