Abstract: A method to produce a rod tag and tag produced according to the method, wherein the method comprises at least the steps of: providing a magnetic core having a cylindrical shape and two end, winding a wire around said core to form an antenna, positioning in longitudinal extension a chip at one of the ends of said rod where the wound wire ends terminates, bonding said wire ends to contacts of said chip, displacing said bonded chip at least partially on said end of said rod, and introducing said core with said wire and said chip in an encapsulating means containing a stabilizing material, whereby the chip is further positioned on said end by the friction between said chip and said material during introduction.
