NFC anti-metal material 125KHZ 13.56MHZ label and elevator access control anti-jamming material for reader reader

RFID NFC anti-metal material, absorbing material, magnetic isolation material The wave absorbing material is a kind of functional composite material that mainly absorbs electromagnetic waves, eliminating the back and forth reflection of electromagnetic waves in the shielding cavity, reducing the interference of clutter on its own equipment, and also effectively preventing the harassment and damage of electromagnetic radiation to surrounding equipment and personnel. An advanced method to eliminate electromagnetic wave pollution. Common thickness includes: 0.08mm 0.1mm 0.2mm 0.3mm

In handheld devices such as NFC payment mobile phones, electronic tags must be integrated or attached to electronic devices to function as a part of the device. Due to limited space, it is inevitable to affix RFID tags (usually passive) to metal And other conductive objects on the surface or in close proximity where there are metal devices. In this way, the alternating electromagnetic field induced by the tag excited by the signal emitted by the card reader is easily affected by the eddy current attenuation effect of the metal, which greatly weakens the signal strength and causes the reading process to fail. Therefore, in order for the product to better use card reading, it is necessary to add absorbing materials to the product.
