Many people have heard of RFID, but do you know the shielding materials that RFID requires? Advanced Institute Technology takes you to broaden your knowledge.
RFID typically requires
Shielding materialWhen the RFID tag is detected by the reader, it will send out electromagnetic wave signals, which will be received and decoded by the reader. If there is no shielding material, these electromagnetic wave signals will interfere with the reader and affect its normal operation.
Therefore, when using RFID, it is usually necessary to use shielding materials to reduce the interference of electromagnetic wave signals. Common shielding materials include metal materials such as copper, aluminum, steel, and iron, as well as metal alloys such as copper, aluminum, steel, and iron. These materials can form a
Electromagnetic shielding layerIsolate the electromagnetic wave signal between the RFID tag and the reader to protect the RFID tag from interference. In addition, some polymer materials such as polyester and polytetrafluoroethylene can also be used as RFID shielding materials.
RFID signal shielding fabric is a type of shielding fabric used to protect electronic tag (RFID) signals. It is a high-strength and highly sensitive fabric that can effectively prevent electromagnetic interference and protect electronic tags from external influences. The main components of RFID signal shielding fabric are fibers and shielding agents. There are many types of fibers, such as polyester, nylon, acrylic, etc. Shielding agents can be metal oxides, electromagnetic shielding agents, or polymer materials.
In addition,
RFID signal shielding fabricIt can also be used to protect other electronic tags, such as clothing, shoes, bags, etc. The application of RFID signal shielding fabrics is very extensive, such as in the fields of clothing, shoes, luggage, etc. These fields require the use of RFID signal shielding fabrics to ensure their safety and stability. Meanwhile, RFID signal shielding fabrics can also be applied in medical, military, transportation and other fields to improve efficiency and accuracy in these areas.
The application fields of RFID signal shielding fabrics are very extensive,
For example, it is suitable for various electronic products such as barcode scanners, data collectors, vending machines, attendance machines, access control systems, anti-theft alarm systems, industrial control equipment, medical instruments, transportation vehicles, mobile payments, anti-counterfeiting traceability, identity recognition, logistics tracking, warehouse management, asset management, security and loss prevention, financial insurance, anti-counterfeiting and anti leakage, one card, self-service, unmanned operation, smart cities, intelligent transportation, smart agriculture, Internet of Things, robots, etc.
The main functions of RFID signal shielding fabric are: to suppress the interference of external magnetic fields and ensure the normal operation of internal chips; Reduce the magnetic field strength within the protected area to avoid the impact of heat generated by external magnetic fields on internal chips.
