Each of the input/output signal cables is connected to the terminal block. Each of the RFID tags is connected to each of the input/output signal cables. The RFID reader transmits information of the RFID tags to an external management system. The check system further includes an RFID communication line(104) for connecting serially a plurality of RFID tags with an RFID reader. The RFID tags are serially connected to each other.
