  • Publication number: 20200402429
    Abstract: Provided is a computing technology for controlling information display of an electronic shelf label that is connected to a management server via a network and displays electronic information. The electronic shelf label measures a distance to at least one product arranged behind the electronic shelf label, and when a change in the distance occurs, activates a wireless tag reader. When product identification information acquired by the wireless tag reader is different from currently displayed product identification information, the electronic shelf labels request a label change registration to a server. Changed product information is received according to the label change registration, and the changed product information is reflected in displayed product information.

  • Publication number: 20200394939
    Abstract: Disclosed is computing technology for managing information display of an electronic label which is connected to a management server via a network and displays electronic information. A moving device transmits images, which are obtained by photographing an electronic label and a product while being moved in a store, to a management server. The management server analyzes the images to extract information and detects changes in displayed products to register changed information. The management server performs inventory management using the extracted information. Further, the management server uses the extracted information to inform a store manager so that a location of a displayed product deviated from a place thereof is corrected.
