Nail trend has surprising tech purpose

It seems like nail trends come around as often as new Starbucks drinks -- all the time.

Recent nail trends have been awesome. We've seen everything from nails with live flowers to amazing, eye-opening colors.

But this recent nail invention takes the cake for awesome ideas.

Fashion student Lucie Davis created acrylic nails that also double as her public transportation pass.

That's right, she barely has to move a finger to move hundreds of miles.

Davis, a student at the University of London's Central Saint Martins art and design school, pulled off the stunning and helpful look with an RFID chip -- something that's already popular in the body modification world.

The chips are tiny, and can be coded to interact with apps of all sorts, including payment ones.

Davis was assigned to create something that was inspired by her daily activities, and she went with a task that is as mundane as it gets and made something amazing.

Davis, who'd been assigned to create something that was inspired by her daily activities, embedded one such chip into a nail for an easy, breezy swap for London's Oyster card.

Here's a video of her incredible invention at work:
