Fingernails that sense NFC signals

Lumi Deco LED enhanced fingernails have been created by the Japanese company Takara Tomy Arts. These “smart nails” are fully equipped with sensors to notify the wearer when the wireless near-field communication (NFC) functionality of another smartphone is in close proximity to the nail-bearer's location. NFC is the capability that some smartphones have, establishing radio communication abilities when two devices are brought together. With NFC, users can connect, exchange data, and complete tasks using radio-frequency identification (RFID).

There are no batteries, capacitors, or power sources that enable these LED nails to flash. It works by feeding off the NFC signal of other Android devices. The nails have embedded LEDs and minuscule antennas that actively illuminate when a nearby wireless NFC device is detected from a smartphone, digital cash IC card like PASMO, mobile wallet functions, or NFC-enabled gaming devices. All the LEDs need is the NFC signal to flash.

This type of wearable technology sticks directly to your fingernails and comes in a set of 16 nail stickers. There is an app for Android devices that allows users to customize a pattern for the LED flashes to emit. The price will be set at around $12 for this bedazzled and luminescent manicure.
