A handy terminal allowing an object of interest such as a cargo to be efficiently searched utilizing an RFID tag is provided. A detection unit detects the distance and direction of an RFID tag attached to an object of search from a point for observing the distance and direction. A reading unit reads information on the external shape of the object of search written in a memory portion of the RFID tag. An image processing unit displays a three-dimensional graphic of the disposition of the RFID tag based on the distance and direction detected by the detection unit and compositely displaying a three-dimensional appearance image of the object of search estimated from the external shape information of the object of search read by the reading unit in the position where the three-dimensional graphic of the RFID tag is displayed.
