A Manicure That Doubles As A Subway Card?
Especially if you're the type who's constantly misplacing your train card. For her final graduate project, Davis designed a set of acrylic nails that also doubles as an Oyster card, the plastic card with which Londoners pay for rides on the tube.
It's as simple as it is genius: Davis took the RFID microchip built in to the Oyster card and embedded it into a full set of acrylic nails. The card reader on the turnstile picks up the chip just as it would in a plastic card.
Instead of fishing through a purse or pulling out a wallet, Davis taps her nails onto the card reader and walks on through.
