It is mainly used for metal cards, and is also applied in near-field wireless communication (NFC/RFID). When placed between the NFC antenna and the phone battery or the metal back cover, it can effectively prevent the interference caused by the metal's eddy currents, thereby ensuring the reading and writing distances and sensitivity of functions such as payment and access control.
Product Introduction
Ketian Ferrite Absorber Material effectively resolves the chip signal interference issue of metal/semi-metal smart cards with its excellent electromagnetic shielding and signal isolation performance, ensuring stable reading and writing of cards in complex electromagnetic environments. It also features high temperature resistance, aging resistance, environmental protection and non-toxicity, fully complying with the high-end process and safety standard requirements for smart card production.
Moreover, as a professional manufacturer of smart card base materials, our Ferrite Absorber Material combines outstanding electromagnetic absorption efficiency with excellent process compatibility, making it a reliable choice for smart card producers worldwide.
