Abstract

Disclosed is a method and apparatus for activating a gaming machine. The invention includes generating a visible light column at a light generating end when the gaming machine is in a ready state. The invention further includes receiving the visible light column at an a light intensity determining circuit. The light intensity determining circuit being configured to monitor disturbances along the visible light column. Then, activating the gaming machine when the light intensity received at the light intensity circuit moves beyond a predetermined level while in the ready state.
