Smart rings are tiny wearable computers designed to be worn on your finger. Despite their small size, these devices are equipped with sensors and can perform functions similar to larger wearables.

These rings connect to other smart devices like smartphones using Bluetooth or NFC. The sensors gather data, which is then sent to a connected app for processing. This data can include heart rate, sleep patterns, and hand gestures for controlling smart home devices.

Uses of Smart rings:

Health and Fitness Tracking: They monitor physical activity, heart rate, sleep, blood oxygen levels, and stress.

Smart Home Control: Some can control smart home devices using gestures.

Contactless Payments: Certain rings have NFC for making payments.

Notification Alerts: Many rings can notify you of calls, messages, etc.
