Smart rings have been in development for years. But only recently have a number of brands emerged that have created smart rings that look good, feel good and pack useful tech into such a tiny form factor.
Put simply, a smart ring is a ring that's got some kind of tech built into it, whether that's an NFC chip , you can use smart ring to open door or smart phone to scan it.
Most of them can also sync up to your smartphone via Bluetooth, enabling you to find out more about the data they're collecting. However, just because a device is called a smart ring doesn't mean it's necessarily packed with tech. A number of different smart rings are currently on the market.
