摘要： A wireless IC device includes an element body including first and second principal surfaces, an RFIC element buried in the element body, and an antenna coil disposed in the element body. The antenna coil includes a first wiring pattern provided on the second principal surface, a first metal pin reaching the first principal surface and the second principal surface, a second metal pin reaching the first principal surface and the second principal surface, and a second wiring pattern provided on the first principal surface. Terminal surfaces of the first input/output terminal and the second input/output terminal of the RFIC element face the second principal surface of the element body and are spaced away from the antenna coil while being connected to the first wiring pattern through first and second conductors extending from the second principal surface of the element body in a direction of the first primary surface.

摘要： 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.
