Abstract
An article management system includes multiple reader devices that read the RFID tags attached to the articles. Moreover, a central terminal partitions an article management area into multiple middle areas that are in turn partitioned into small areas, and then causes reader devices arranged in two or more small areas to work in a predetermined order for each small area, to read information of the RFID tags. The range of radio wave interference distance assumed for a reader device in a first middle area partially overlaps with a second middle area. Thus, when causing the reader devices arranged in the first middle area to work in order, the central terminal controls a reader device in the second middle area that lies outside the range of radio wave interference distance from a reader device working in the first middle area.
