Presuming your mother is anything like mine, you’ve heard that if you got a tattoo you’d later regret it. Not to mention the whole it-being-visible-during-job-interviews thing. But what if you had a tattoo that was only visible sometimes? And I don’t mean because it’s in an unmentionable spot. Instead, because it was literally only visible in certain conditions.
That’s what Anthony Antonellis set out to do when he had a small RFID chip implanted inside the fleshy back of his hand between his thumb and forefinger. The chip, stored in a glass capsule, has 1KB of storage and is completely invisible.
That is, completely invisible until you hold a smartphone to his hand and see the small GIF that’s actually there. At the time of this writing, the GIF is a small rectangle with a rainbow of colors passing through it (click through to the story below to see), but Antonellis has the ability to change it at any time, to anything.
While he’s using it for artistic ends, it wouldn’t be difficult to imagine this as a way to store really, really, really, really, really important data. Though, outside of a movie universe, I can’t imagine what that data would actually be. Maybe it’d be a way to keep it away from the NSA, at least.
Check out a video of Antonellis explaining it below.
