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.
