A system for identifying different types of products on a display hanger and determining a quantity of each of the different types of products includes a plurality of electrically conductive segments coupled to the display hanger, an electrically conductive rail coupled to the display hanger, and a sensor device electrically coupled to each of the plurality of electrically conductive segments and to the electrically conductive rail. The sensor device is configured to identify the different types of products on the display hanger and to determine the quantity of each of the different types of products based on a unique electrical signature associated with each of the different types of products.
