The invention discloses a double-sided contact-type intelligent electronic tag which is characterized by being formed by a circuit board, a connecting piece and a chip, wherein the chip is welded on the circuit board; the part, on which the chip is welded, of the circuit board is inlaid in the connecting piece; the circuit board comprises a pin wire and contact strips; the contact strips are set to be double-sided contact strips, and the double-sided contact strips are all connected with the chip on the circuit board. For the double-sided contact-type intelligent electronic tag disclosed by the invention, through the manner that metal contact strips on the same side are not connected, but are connected with corresponding metal contact strips on the other side, the function that both sides can be identified can be achieved, and therefore, if the metal contact strips on one side are damaged and cannot be used, the electronic tag can be still used, so that the use time of the electronic tag is prolonged, and the cost is saved.
