PROBLEM TO BE SOLVED: To easily manage an article (equipment, a commodity or the like) at low cost.SOLUTION: An electronic tag control device 2 generates identification information including an identifier of an electronic tag 1, transmits the generated identification information into a prescribed propagation area, and the electronic tag 1 receives the identification information transmitted by the electronic tag control device 2. On the basis of the above premise, the electronic tag 1 determines whether the identifier included in the received identification information and its own identifier accord. When determination result indicates accordance, the electronic tag 1 notifies that the electronic tag 1 moves from the inside of a prescribed propagation area transmitted with the identification information from the electronic tag control device 2, to the outside of the propagation area by sound emission by a buzzer or light emission by an LED. Thereby, when installing the electronic tag 1 to equipment 3, it can be notified that the equipment 3 moves from the inside of the prescribed propagation area to the outside of the propagation area. As a result, the equipment 3 can be easily managed at low cost.SELECTED DRAWING: Figure 1 |
