Abstract
Information is stored in an RFID provided to a goods conveyed by a conveying apparatus and from which information is readable in a noncontact manner. A presence detection sensor that detects the presence of the goods conveyed by the conveying apparatus; a reader that reads the information stored in the RFID in the noncontact manner; a moving apparatus that moves the reader; and a control apparatus that controls the operation of the moving apparatus are provided in a system. The control apparatus presumes the presence position, where the goods is present, on the conveying apparatus based on the detection value of the presence detection sensor, and controls the operation of the moving apparatus so that the reader stays, for a predetermined time, in a space where the reader can read the information from the RFID that is present in the presumed presence position.
