A smart ring is a compact wearable electronic device that combines mobile technology with features for convenient on-the-go use. These devices, typically designed to fit on a finger like a traditional ring, offer functionalities like mobile payments, access control, gesture control, and activity tracking. Smart rings can connect to smartphones or other devices, and some can operate independently, communicating with cloud-based systems or performing standalone tasks. While lacking traditional displays, they respond to contextual cues, such as proximity to payment terminals or specific gestures.^[1]

In 2013, the British company McLear, co-founded by John McLear, Chris Leach, and Joe Prencipe, introduced the first commercially available smart ring.^[2] Today, a multitude of companies produce smart rings for various use cases, expanding the options available to consumers.
