How NFC tag absorbing plates effectively absorb reflected electromagnetic waves from metal surfaces

Today, with the rapid development of Radio Frequency Identification (RFID) and Near Field Communication (NFC) technologies, NFC tags are widely used in various fields such as smart retail, logistics tracking, and identity verification. However, when NFC tags are placed on a metal surface, the electromagnetic waves reflected by the metal can interfere with the communication between the tag and the reader. Advanced Institute (Shenzhen) Technology Co., Ltd. launchedResearch Platinum NFC Tag Absorber PlateAiming to solve this problem by effectively absorbing reflected electromagnetic waves generated by metal surfaces and optimizing the performance of NFC tags.

The Influence of Metal Surface on NFC Tag Performance

Due to its conductive properties, metals can reflect 13.56MHz electromagnetic waves emitted by NFC tags, causing difficulties in reading, shortened communication distances, and even complete inability to read. Reflected waves may also cause misreading or data errors, seriously affecting the performance and reliability of NFC systems.

Working principle

Research Platinum BrandNFC tag absorbing plateThe material adopts a special formula, which has the characteristics of high magnetic permeability and low electrical resistivity. It effectively absorbs reflected electromagnetic waves from metal surfaces through the following mechanisms:

1. Electromagnetic wave absorption: When electromagnetic waves encounter absorbing plates, high permeability materials guide the electromagnetic waves into the interior of the material.
2. Energy Conversion: Within materials, electromagnetic energy is converted into other forms of energy, such as thermal energy, thereby reducing reflection.
3. Impedance matching: The absorption plate is designed to match the impedance of free space and reduce the reflection of electromagnetic waves.

Performance advantages

1. Efficient absorption: According to the test data provided by Advanced Institute (Shenzhen) Technology Co., Ltd,Research Platinum Plate Absorption Wave PlateCan reduce the intensity of reflected waves by more than 90%.
2. Improved communication: Experiments have shown that using a platinum absorbing wave plate can increase the reading distance of NFC tags by 50% on metal surfaces.
3. Durability: This wave absorbing plate has good temperature and moisture resistance, suitable for various environmental conditions.
4. Flexibility: The material is lightweight and flexible, making it easy to cut and fit metal surfaces of various shapes.

case study

In a field test,Advanced Institute (Shenzhen) Technology Co., LtdApply the platinum brand NFC tag absorbing plate to the tracking system of the automotive manufacturing chain. Without attaching a waveplate, the success rate of reading NFC tags on metal parts is only 60%. After using the Research Platinum brand absorption wave plate, the success rate of reading has increased to over 98%, significantly improving the accuracy and efficiency of production tracking.
Taking a certain NFC access control system as an example, the system needs to attach NFC tags to metal doors to achieve access control. However, due to the reflection effect of the metal door, the NFC communication distance and stability are seriously affected. By using the R&D Platinum NFC tag absorbing plate, this problem has been successfully solved. Experimental data shows that after adding a wave absorbing plate, the NFC communication distance has increased by about 30%, and the communication stability has also been significantly improved.

conclusion

The research platinum brand NFC tag absorbing plate has proven its effectiveness in various application scenarios due to its excellent absorbing performance and durability. It not only improves the communication efficiency of NFC tags on metal surfaces, but also expands the application scope of NFC technology. With the development of Internet of Things technology and the increasing use of NFC applications, the Research Platinum NFC tag absorbing plate will become a bridge connecting the physical world and digital information, providing strong support for intelligent management and automated operations.
