ARTICLE MANAGEMENT SYSTEM AND ARTICLE MANAGEMENT METHOD

摘要

With a conventional article management system the articles being managed cannot be individually identified. An article management system according to the present invention has: a reader antenna (102) that transmits and receives wireless signals; multiple tag sheets laid on the upper part of the reader antenna (102) and each of which contains an RF tag (104); an RFID reader (103) that reads tag information specific to the RF tags (104) via the reader antenna (102); and identification marks that are attached to articles (31-34) being managed and arranged between the articles (31-34) being managed and the tag sheets. An identification pattern, which identifies the indication mark by means of a first pattern and a second pattern having a lower permittivity or conductivity than the first pattern, is formed on the tag-sheet-facing surface of the identification marks.
