Abstract
An article management system includes RFID tags () fixed above a reader transmission line (), a metal sheet () having an opening () at positions corresponding to RFID tags () located within an assigned position () assigned to place an article (), a tag reading unit () that reads the plurality of RFID tags () by electromagnetic coupling through the reader transmission line (), and an article presence/absence determination unit () that determines presence or absence of the article () at the assigned position () on the metal sheet () based on results of reading the plurality of RFID tags (). It is thereby possible to manage articles at high speed even when a plurality of RFID tags are placed.
