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.

Abstract: A flexible Radio-Frequency IDentification (RFID) tag comprises a flexible substrate layer on which is fixed an antenna connected to a RFID chip, and a second flexible layer placed directly over the said chip and antenna but without any direct mechanical connection to them, such that the substrate layer and the second layer form a protective inlay for the chip and the antenna. The said inlay is embedded in a flexible housing.

Abstract: The card (1), such as a credit card or other similar card, comprises at least a RFID chip module (3) and an antenna (4). The antenna (4) is interrupted in an interruption zone with two separated contact ends (5?,5?) and a contacting material (10) is placed in said interruption zone in order to enable a contact between said two separated ends (5?,5?). Said contacting material (10) becomes conductive under pressure so that the antenna is functional only when the contacting material (10) is put under pressure by a user.

Abstract: The invention relates to a transponder device which comprises a chip (5) and an antenna (8), the chip (5) being connected to the antenna (8), the transponder is characterized by the fact that the chip (5) is packed with a protective and insulating layer (14) of at least 30 ?m thick, the layer being at least arranged between the chip (5) and the antenna (8), the antenna (8) being connected to the chip (5) through said layer (14).
