W5Networks at Demo
W5 Networks are in the process of replacing paper price tags in supermarkets and stores to electronic shelf labels. This in essence means instantaneous price updates and changes made to all products store-wide as it goes on sale, or is part of a promotion. There’s an LED that displays the price, and the central control makes sure all prices are accurate and up-to-date. Again very 21st Century, and should be there in every store soon enough.
