Anti-metal materials are also called metal insulation materials, ferrite materials, anti-interference materials for electronic tags, and are also commonly known as "magnetic cloth". Suitable for 13.56MHz/125KHz high-frequency cards/low-frequency cards, can be packaged into anti-metal tags, not only enables the tags to be used normally on metal and electromagnetic surfaces,
effectively reduces the absorption of antenna signals by metals, thereby increasing the antenna's sensing distance, Improve the performance of the antenna. Anti-metal tags are attached to the surface of metal products, and the induction range is generally 1~10cm. Anti-metal smart card refers to the use of anti-metal material as a liner to play a role in preventing metal interference on the radio frequency card, to ensure that even if the radio frequency card is attached to the surface of a metal object, the card reader can read or write the IC chip. The anti-metal smart card makes full use of the lamination and punching process in the production of smart cards. It has the characteristics of simple and fast production process, and can produce anti-metal PVC smart cards of any size and specification.
