A reader for an RFID system is provided to recognize various recognition targets by using one reader and one of a plurality of attachable antenna modules corresponding to a tag of the recognition targets having a different frequency band while keeping a basic configuration of the reader. A front unit(12) arranged to a front end of a reader body(10) comprises an MCU(Micro Control Unit)(24) and an FBS(Frequency Band Setting) logic unit(30). A serial interface(32) connected to the antenna module(14) is arranged to the front end of the FBS logic unit. The antenna module forms an antenna and a transformer of the tag by being selected according to the frequency band of each recognition target. |
