Abstract
An identification tag is attached to or imbedded in each article a plurality of which are located nearby or stacked together. The identification tag wirelessly communicates with a remote controller such as a hand-held terminal to send data or receive command. Electric power to operate the identification card is also wirelessly supplied from the remote controller. The electric power is received only by a particular identification card which is communicating with the remote controller, and is turned off when the communication is completed. The electric power is then supplied to the next identification card which communicates with the remote controller. Thus, all the identification tags sequentially send data thereof one by one to the remote controller. The remote controller includes an indicator that indicates whether the communication with all the identification tags is completed, so that the remote controller can be positioned at a right place until the end of the communication.
