What is a Smart Ring?
A smart ring is a small wearable device worn on your finger that offers features similar to fitness trackers and smartwatches. It combines technology like sensors, Bluetooth, and NFC into a discreet ring that looks like jewelry but works like advanced wearable tech.
How do Smart Ring Work?
Smart rings use miniature sensors embedded in the ring’s body to track data such as heart rate, sleep patterns, and activity. They connect via Bluetooth to your smartphone, allowing you to view health metrics in their dedicated apps. Some smart rings also have NFC chips for payments or access control. They are powered by small rechargeable batteries and often use proprietary chargers that connect magnetically.

- NFC: For contactless payments or digital keys
- Battery: Lasts from 3 to 7 days depending on model and usage
- Charging: Usually via a small dock or USB magnetic charger
