PMA EMC card built-in high technology chipset, it is made by ferrite absorbing materials and more than 10 kinds of rare elements. According to regular of electromagnetic wave transmits from low magnetic permeability to high magnetic permeability, EMC anti-radiation card can absorb radiation which is nearby human body, and Using high magnetic permeability ferrite absorbing chip inside card to lead electromagnetic wave priority transmit, and processing coupling resonance to transfer electromagnetic energy to heat energy and emit heat to air.


PMA EMC card willprotect human body in a circle which is in dia 60cm with card the center decay radiation, it can be effectively eliminated radiation that harmful to human body.
