The NFC Ring is made of an Advanced Ceramic and is water resistant. By programming NFC Ring, you can automate tasks such as unlocking your phone, doors, make payments, or access websites or application without entering password.
Built into to the ring are two NFC (Near Field Communication) transmitters, one for public information and one for private data. Writable space is 888 bytes. 8 millimeter wide ring doesn’t have batteries and there is no need for charging.
The NFC Ring has no display, which would be great addition.
