Do you know the difference between metal resistant labels and regular labels?  Anti-metal label refers to the label that can realize wireless communication (antenna, label, module, card) affixed with absorbing material.  After the magnetic material ferrite, it can be combined with metal to realize induction smoothly.  Absorbing material is a kind of functional composite material which mainly absorbs electromagnetic wave.  It can eliminate the back and forth reflection of electromagnetic wave in the shielding cavity, reduce the interference of clutter to its own equipment, and also effectively prevent the electromagnetic radiation from harassing and hurting the surrounding equipment and personnel.  It is a means to eliminate electromagnetic wave pollution.  High frequency anti-metal label Add absorbing material (anti-metal material magnetic cloth) on the surface of the label, which can be used on metal articles to isolate metal interference, and the reading speed is fast.
