A locket includes a chamber and a door, with the chamber housing an electronic display, a microprocessor with associated memory coupled thereto, a wireless transceiver coupled to the microprocessor, and a power source. Messages/pictures can be displayed on the display through use of a system incorporating the locket, a mobile unit having a locket application and a wireless transceiver, and an application server device with a database. The system may also include a separately networked computer-type device. A locket user can log into the application server, register the locket, and create a user profile including one or more of interests, personal information, social connections, etc., that would establish how the locket can receive content. The system allows permitted friends to send messages/pictures through the application server to the locket for display.
