Zusammenfassung:To provide an RF tag system which enables use of general-purpose inlays and reader-writers without requiring a complex configuration, structure, and the like, and ensures reliable communication only with a target RF tag from among a plurality of necessary tags without errors.SOLUTION: An RF tag system 1 comprises a transceiving antenna 11, RF tags 20, and a relay device 30. The relay device 30 comprises conductors 31 and a support 32 for supporting the conductors 31 and is installed at the middle between the transceiving antenna 11 and the RF tags 20. The conductors 31 are configured to re-emit a radio wave received from the transceiving antenna 11 or the RF tags 20.SELECTED DRAWING: Figure 1 【課題】複雑な構成・構造等を必要とすることなく、汎用のインレイやリーダ・ライタをそのまま使用可能で、かつ、必要な複数のＲＦタグの中から目標となる対象のＲＦタグのみと誤りなく確実に交信する。【解決手段】送受信アンテナ１１とＲＦタグ２０と中継装置３０とを備えたＲＦタグシステム１であって、中継装置３０は、導体３１と、導体３１を支持する支持体３２とを備え、送受信アンテナ１１とＲＦタグ２０の中間に設置され、導体３１は、送受信アンテナ１１又はＲＦタグ２０から受けた電波を再放射する構成としてある。【選択図】図１
