Report: Japanese co. introduces diamond ‘smartring’
One Tokyo-based company has just upped the ante on wearable technology, introducing a diamond ring outfitted with near-field communication capabilities. See how it works in this video from Core Jewels.
Tokyo--One Tokyo-based company has just upped the ante on wearable technology.
While there are rings that connect to the wearer’s smartphone, bracelets that monitor how much they walk and even 18-karat gold versions of Apple’s new smartwatch, not many, if any, of these products are set with diamonds.
Enter “One,” a line of diamond and gold rings outfitted with near-field communication technology, also known as NFC.
NFC is the type of communication that takes place between smartphones/tablets and other devices. Users simply wave or hold up their smartphones/tablets in front of other devices to transmit information; they don’t have to touch the devices together or connect them in any way. QR codes, for example, use NFC as do e-money systems like Apple Pay or Google Wallet.
Created by TSLJ Co., which owns Japanese jewelry company Core Jewels, the rings can be used to unlock private data saved in cloud storage or as a way to access private information, such as wills, according to a report by Japan Real Time, a blog of The Wall Street Journal. The rings, however, cannot be used for e-money payments or to unlock smartphones--yet.
They are compatible with NFC readers on computers or Android devices.
The rings will retail for a maximum of about $3,600, according to the report. TSLJ, which says they are the world’s first diamond rings outfitted with NFC, will begin taking orders for One rings next week. They’ll be available beginning in December.
TSLJ Co. did not respond to National Jeweler’s request for more information on the rings.
