Adafruit RFID / NFC Smart Ring - Size 7 - NTAG213

Amidst the mystical aura of Middle Earth, the One Ring's tale took a modern twist with the RFID/NFC Smart Ring, a marvel that even Mount Doom couldn't foresee. This innovative ring houses two MiFare Ultralight C - NTAG 213 tags, each boasting 144 bytes of read/write memory.

Enabling seamless interaction between your ring and smart devices, it allows for launching apps, unlocking phones, transmitting URLs, or even controlling Arduino projects. Encapsulating the essence of near field communication, similar to a short-range Bluetooth without authentication, it brings forth an array of RFID/NFC capabilities.

Featuring a 17mm inner diameter, the ring is compatible with any NFC/RFID reader supporting ISO 14443-3A MiFare Ultralight/NTAG. Dive deeper into the possibilities of RFID/NFC through the Adafruit Learning System, where technology meets creativity.
