Abstract: A method and apparatus for a chip tracking system. For example, an apparatus comprises a chip tray and a tracking controller. The chip tray has a plurality of light sensors positioned inside a column. In some instances, the tracking controller is configured to perform operations that cause the apparatus to detect a level of ambient light at each of the plurality of light sensors and determine, in response to detection of the level of ambient light at each of the plurality of light sensors, a number of gaming chips placed inside the column. The tracking controller is further configured to perform operations that cause the apparatus to compute, in response to determination of the number of gaming chips, a chip-column value. In some instances, the tracking controller is further configured to automatically indicate the chip-column value via one or more electronic devices communicatively coupled to the chip tray.

Abstract: A gaming system includes a gaming machine for conducting a casino wagering game and logic circuitry. The logic circuitry establishes a gaming session of the casino wagering game for a player, during the gaming session, detects an object at a detected distance via a presence sensor of the gaming machine, determines whether or not the detected object is the player based on one or more object detection criteria including the detected distance, in response to the detected object being determined to be the player, maintains the gaming session, and in response to the detected object being determined to be an object other than the player, initiates an end-session counter to terminate the gaming session. A duration of the end-session counter varies at least partially as a function of the one or more object detection criteria.
