Electromagnetic wave shield (roll) curtains prevent misreading of nearby non-target IC tags in logistics and production sites that use RFID electronic tags.
- Measures against Wi-Fi radio waves and wireless radio wave measures are supported. - UHF band IC tags are being widely adopted, particularly in logistics applications, due to their convenience in reading a large number of IC tags over a wide area. However, because the communication distance is several meters long, it often ends up recognizing IC tags that should not be recognized. - To prevent misreads, there are methods to shield radio waves using shielded mesh or radio wave absorption panels. However, considering the flow of goods and people in logistics and production sites, the installation methods and locations for these solutions are limited, making it difficult to shield radio waves and implement UHF band IC tags in some cases. - The shielded roll curtain is a roll screen type that can be retracted and stored when not needed, allowing for accurate reading of IC tags without obstructing the flow of goods and people.

Live restaurant glass surface (night view) There is a huge glass surface measuring 9m high and 16m wide behind the stage inside the restaurant, designed to provide a view of the outside. On the other hand, there is a significant challenge of how to escape from interference from external radio waves.
-
Live restaurant performance stage (curtain closed) To create an electromagnetically shielded space within the store, it is necessary to cover all six surfaces of the store's walls, floor, and ceiling with highly conductive materials. Furthermore, all surfaces must be electrically connected without any gaps. A major issue was the presence of glass sections. At the same time, we decided to proceed with a final target value for the shield of 30 dB.
