Electronic shelf label system

摘要

If an electronic shelf label server receives a replacement request from each of the electronic shelf labels, a date of a corresponding electronic shelf label number is read out from a database and an object range is determined based on this date. Then, whether or not a date corresponding to the electronic shelf label number is within the determined object range is determined so as to specify an electronic shelf label which should be replaced. Information of this specified electronic shelf label is displayed on a display.
