Abstract
According to one aspect of the present disclosure, a gaming system with a chip tray positioned above a light-diffusion box. The chip tray has a transparent portion on its underside. A tracking controller illuminates the light-diffusion box with diffused light that shines through a transparent portion on an underside of the chip tray and illuminates the edge of one or more chips in a chip stack. An image sensor captures an image of the one or more chips in response to illumination of the light-diffusion box. The tracking controller analyzes a visible indicator on the edge of the one or more chips. The tracking controller associates the visible indicator with a denomination value for the chip stack. Further, the tracking controller computes a value of the chip stack based on the denomination value and a dimension of at least one of the one or more chips.
