An identification system includes a mobile computing device having a memory and an establishing module establishing an identifying data set stored in the memory. The identifying data set includes an accumulated data gathered at the mobile computing device over an establishing period and is capable of uniquely identifying a user corresponding to the mobile computing device.

A wearable electronic device comprises a ring body defining an annular receiving space within the ring body and a substrate disposed in the annular receiving space. The ring body has an interface disposed on an exterior of the ring body. The substrate has a plurality of capacitive plates positioned proximate the interface.

A ring assembly including a shank having a band defining a head mounting area with a keyhole aperture defined in the upper surface of the band in the head mounting area, wherein the keyhole aperture defines an entrance to a cavity; and a head including a mount with a base and sidewalls, and a post extending from the exterior of the base of the mount, the post including at least one protruding key configured to pass through a corresponding opening in the keyhole aperture and engage the cavity to releasably secure the head to the shank. Methods for forming and demonstrating ring assemblies are also disclosed.

A ring assembly including a shank having a band defining a head mounting area with a through hole defined through the band in the head mounting area. The through hole defines internal threads; and a head including a mount with a post extending therethrough, the post including an area of external threads configured to engage the internal threads to releasably secure the head to the shank. Methods for forming and demonstrating ring assemblies are also disclosed.
