RFID/NFC Nail Stickers - 5 Pack with White LEDs
You're at New York's hottest cyberpunk club is Near Field Commune(ication), and it's got everything, Adabot & the Circuit Playground, Collin's wondrous, mind-blowing, heart-stirring Pulse Room, and more! And you are dressed to the cyber-nine's, with wearable LEDs, EL tape, and a full manicure set of glittering RFID/NFC Nail Stickers!
These tiny flexible PCBs have a coil, transistors and a little LED on them - when in the range of an RFID or NFC reader (such as that in your phone) the coils pick up the electromagnetic energy emitted and use them to blink the LED for a cool cyberpunk effect - no batteries required! These are seriously cool wearable LEDs that light up when close to contact-less payment terminals, NFC smartphones, 13.56MHz RFID card door locks, etc.
Note that these stickers do not actually act as an NFC/RFID tag, they don't transmit any data back - they only blink the LED when in the presence of a ~13MHz RFID electro-magnetic field.

One order includes 5 nail stickers, you can reuse them and if the sticky part wears down, you can use standard double-sided nail tape, the kind used to attach acrylic nails.
