PROBLEM TO BE SOLVED: To allow an image display device to communicate with a non-contact tag regardless of the installation position or method of the image display device.SOLUTION: An image display device comprises a plurality of non-contact tags and an image control device. Each of the non-contact tags comprises: a communication unit for communicating with an external apparatus; a control unit for generating update information indicating the reception of data and reception time information; and a storage unit for storing the received data, the update information, and the reception time information. The image control device comprises a setting storage unit, a determination unit, and a main control unit. The determination unit determines whether at least one non-contact tag has received data from the external apparatus on the basis of the update information. If the determination unit determines that data has been received, the main control unit identifies a non-contact tag on the basis of the reception time information, obtains the data from the storage unit of the identified non-contact tag, and write it into the setting storage unit.SELECTED DRAWING: Figure 2 |
