Abstract: This disclosure describes, in part, systems for tracking the removal of shopping bags or other items from a dispenser. Folded shopping bags are stacked in a holder so that a front shopping bag can be removed by pulling it along an axis that is parallel to the length and/or width dimension of the shopping bag. A motion sensor is positioned to sense movement of the front shopping bag as it is removed. Control logic monitors and/or analyzes data or other signals from the motion sensor and determines whether movement of at least a threshold distance has occurred. If movement of at least the threshold distance has occurred, the control logic concludes that a shopping bag has been removed and generates a corresponding event notice. Other system components may respond to the event notice by applying a charge for the removed shopping bag or by performing other actions.
