Electronic Shelf Label Systems (ESL Systems) are digital price tag solutions installed on retail store shelves to replace traditional paper labels. The complete system consists of electronic shelf labels, wireless communication gateway, cloud/on-premise management software and supporting accessories. Merchants can synchronize product prices, promotions, descriptions and inventory information remotely in real time. It reduces manual label replacement labor, eliminates paper waste and improves pricing accuracy. Widely deployed in supermarkets, grocery stores, pharmacies, electronics retail, fashion shops and warehouses.
