<p>Provided is a tri-state electronic tag, which is characterized by comprising a tag chip (1), and a near-state tag antenna (2) and a far-state tag antenna (3) for receiving/transmitting wireless waves, the near-state tag antenna (2) being in conductive connection with the tag chip (1) in a separable manner, and the far-state tag antenna (3) being in conductive connection with the near-state tag antenna (2) in a separable manner. By adopting the structure of the present invention, an electronic tag is able to realize a read-write state at a relatively far distance, a read-write state at a relatively near distance when the read-write cannot be done at a relatively far distance and a read-write-incapable state, so that it can play a more positive role when applied to the Internet of Things.</p> |
