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.
