Xenxo is made up of the most up-to-date touchscreen and chips: Bluetooth 5.0, NFC module, Accelerometer, 4 Gb memory and microphone speakers. This made it possible to turn the usual accessory into a multifunctional apparatus. For this reason, manufacturers called the device the most "smart" ring.

First of all, developers suggest using the ring as a headset. With the help of a special button on the case, you can take a call or call a favorite contact or send an SOS signal. For a conversation, you need to put your hand with the ring to your ear.

Through NFC, you can pay for purchases with a ring. Only it is unclear how the device will be protected from accidental withdrawals, because there is no password, fingerprint scanner or face, as in smartphones. The built-in ring memory can be used to store personal data instead of a flash card, and Bluetooth for opening doors with special locks.

Still there are some small functions. For example, a ring can switch music on a smartphone or use it as a personal alarm clock that will gradually start to vibrate.
