Smart Ring(NFC Ring)

A smart ring is a wearable electronics device with advanced mobile components that combine features of mobile devices with innovative features useful for mobile or handheld use. Smart rings, which are typically the size of traditional rings or larger, combine the features of a mobile device, such as the ability to make payments and mitigate access control, with popular innovative uses such as gesture control and activity tracking. Smart rings can communicate directly with smart phones or personal computers through a variety of applications and websites, and operate without the need to carry a smart phone, such as when interacting with back-end systems on the cloud through or performing standalone functions such as activity tracking. They typically do not have a display and operate by contextual relevance, such as by making a payment when near a payment terminal, unlocking an electronic lock when near the lock, or controlling home appliances when making gestures in the home. Some smart rings have physical or capacitive buttons to use as an activation mechanism, such as to initiate a gesture.

One smart ring remote control that actually exists is the NFC Ring. NFC stands for near-field communication, a radio protocol similar to radio-frequency identification (RFID).

The NFC Ring can communicate with any other device containing an NFC chip. For example, you can unlock your smartphone or tablet simply by sliding the ring along the back of the device. You can also unlock an NFC-enabled door with a tap of the ring.
