Why is the price of absorbing materials in the NFC payment field high?

Author:admin   AddTime:2021-03-25

Absorbing material refers to a type of absorbing shielding material that can absorb the electromagnetic wave energy projected on its surface. It has a wide range of applications and is often used in mobile phones, tablets, GPS, and even the military.

In the field of NFC and RFID, the absorbing material is mainly used for 13.56MHz magnetic permeability, that is, the magnetic field destroyed by the metal is conducted through the absorbing material (ferrite). Due to the high requirements on the volume of the material, the absorption permeability, etc., one of the main factors restricting the further development of NFC in the future is the cost of the ultra-thin absorbing material or ferrite sheet used in the NFC anti-metal tag. The high cost makes it difficult for NFC to popularize on low-end smartphones. However, with the development of the industry, the cost of absorbing materials will inevitably be gradually reduced. In the past, the low- and middle-end magnetic powder used in the production of absorbing materials was manufactured by ourselves, but the high-end magnetic powder was mainly imported. Importing this part of the magnetic powder causes the cost of high-end absorbing materials to remain high.



After continuous improvement of product research and development, the performance of magnetic powder produced in China can reach the performance of imported magnetic powder. Using self-produced high-performance magnetic powder instead of imported magnetic powder, the production cost will come down immediately. I believe that in the future, we can also reduce the cost of absorbing materials through technological innovation and continuous improvement of technology. This will make the price of absorbing materials continue to fall, and will play an important role in promoting the popularization of NFC on low-end smartphones.

In addition to NFC payment, absorbing materials will also be used in EMC and wireless charging fields. In addition to NFC electronic tags, the hardware involved in the Internet of Things also includes card readers, computers and other electronic terminals. These terminals may face EMC and wireless charging problems, and also need to use absorbing materials.
