Abstract: An electronically detectable display and monitoring system are disclosed. The display (10) includes a body (30) and an electronically detectable node (20). The body (30) has a first state and a second state. The electronically detectable display includes a signal blocking member that prevents detection of the electronically detectable node (20) when the body (30) is in the first state. The monitoring system is arranged to monitor the display for the electronically detectable node.
