A low product stock display system (124) for detecting a least one of fully stocked, partially stocked, and empty (no stock) shelf has been described. The presence/absence of stock can be detected by conductive contact sensors, inductance sensors, weight sensors (90), optical sensors, and, in the preferred embodiment, with an RF transmission line (126). The data from a sensor is wirelessly relayed to an external server for processing across a plurality of facilities, and can provide alerts to personnel or systems (124) responsible for reordering or restocking the particular shelf or display at the facility.
