The Smart Item Label (SIL) shows product details as well as price, sale and stock inventories on an e-paper display. By utilising WAN (Wide Area Network), retailers can change information on smart labels in multiple stores from a central location in real time, without the labels needing to be manually adjusted or replaced. The SIL system allows the matching of accurate prices at an item level between online and offline retailing. With its sleek appearance, the SIL also draws attention to brand equity and enhances the visibility of the products in stores.
