ARTICLE MANAGEMENT SYSTEM AND ARTICLE MANAGEMENT METHOD

摘要

It is impossible to individually identify management target articles in a conventional article management system. An article management system according to the present invention includes a reader antenna that transmits and receives a radio signal; a plurality of tag sheets each including an RF tag and placed on the reader antenna; an RFID reader that reads tag information unique to the RF tag via the reader antenna; and an identification mark attached to each of management target articles and arranged between the management target articles and each tag sheet. On a surface of the identification mark that faces the tag sheets, an identification pattern for identifying the identification mark is formed of a first pattern and a second pattern having a dielectric constant or conductivity lower than that of the first pattern.

1. An article management system comprising:
a reader antenna that transmits and receives a radio signal; a plurality of tag sheets each including an RE tag and placed on the reader antenna; an RFD reader that reads tag information unique to the RF tag via the reader antenna; and an identification mark attached to a management target article and arranged between the management target article and the tag sheets, wherein on a surface of the identification mark that faces the tag sheets, an identification pattern for identifying the identification mark is formed of a first pattern and a second pattern, the second pattern having a dielectric constant or conductivity lower than that of the first pattern.
