The invention discloses an electronic tag and a system, and the detection distance of a first signal detector in the electronic tag is smaller than the detection distance of a second signal detector, so that when a reader-writer is closer to the electronic tag, the reader-writer can read the electronic tag; the first signal detector and the second signal detector can detect a label identification signal sent by the reader-writer. The logic circuit can respond to an indication signal output by the first signal detector and update an initial logic value to a target logic value, and the control circuit can respond to a tag identification instruction, generate an identification code according to the target logic value in the logic circuit and the identification of the electronic tag, and output the identification code to the reader-writer. Therefore, under the condition that the number of the electronic tags is large, even if the reader-writer can receive the identification codes of other electronic tags, due to
