摘要：
An RF tag system includes a first reader/writer unit and a second reader/writer unit. A first reader/writer control unit is configured to control the first reader/writer unit to read a first data from a first RF tag, and to detect a trouble state of the first reader/writer unit. A second reader/writer control unit is configured to control the second reader/writer unit to read a second data from a second RF tag, and to detect a trouble state of the second reader/writer unit. A monitoring section is configured to issue a selection instruction and to monitor the first reader/writer unit through the first reader/writer control unit, and the second reader/writer unit through the second reader/writer control unit. A switching section is configured to select one of the first reader/writer control unit and the second reader/writer control unit in response to the selection instruction from the monitoring section.
