The Retail applies more and more electronic shelf labels in their point of sales. The presentation of goods includes not only the positioning of the product but also the correct and properly price labelling. A big supermarket with about 20.000 products on display has to update prices more often. Fresh food for example can have hourly changing prices, depending on stock and closing time. Digital signage offers various possibilities for optimization:

• Facilitating the work processes for the staff

• Interconnection between customers, products and e-commerce

• Centrally controlled price management per click
