The transponder comprises a rigid casing adapted to be inserted into the wood material by means of impact, the casing comprising a wedge-shaped first edge () adapted to penetrate into the wood material due to said impact, and a second edge () opposite to the first edge, the first and second edges () defining an insertion direction of the transponder, and radio-frequency trans-ponding means () covered by the casing. According to the invention, the casing is elongated in a direction perpendicular to the insertion direction. The transponder is easily applicable into a log and stays well within the log.
