An electronic price tag system for stock keeping units (SKUs) having three components: an ID module, a Remote Display Module (RDM), and a remote display control module (RDCM). The ID module and/or the RDCM may contain display elements. The RDM receives information from a vendor's legacy central computer system (LCCS) or marketing computer system (MCS). Communication between the LCCS/MCS and the RDCM is mediated by an RF Communication Module. The RDCM is reusable and may have a limited transmission range to limit access to LCCS/MCS information and security elements triggered by unauthorized removal. |
