There are plenty of smart ring options available on the market, but what makes Xenxo S-Ring stand out from its peers is the fact that there are over ten features  packed inside this tiny ring, whereas most existing rings are equipped with just two or three.

Once paired with a phone, it supports Bluetooth calls through the built-in earpiece along with front and rear microphones and as well as Siri/Google Assistant compatibility. It offers 4 GB of data storage and comes with a USB dongle. Next, there is an NFC chip in the ring, meaning it can settle contactless payment and can be used as an access card for smart doors. It also helps to monitor health parameters, and can be used as a silent alarm by waking the user via vibration. Other less key, but still useful features, include changing music via gesture control, verbal current time and discreetly sending SOS signal to friends or authorities. Xenxo S-Ring is currently seeking backers on Kickstarter and delivery is expected starting from November 2018.
