Anti-metal tag is a special anti-magnetic wave-absorbing material encapsulated into an electronic tag, from the technical solution to the electronic tag can not be attached to the metal surface to use the problem. The product can be waterproof, acid-proof, alkali-proof, anti-collision, can be used outdoors. The anti-metal electronic label can be affixed to the metal to obtain good reading performance, the use of special circuit design, can effectively prevent the metal on the radio frequency signal interference, to achieve the real anti-metal effect.
