Abstract: The present application provides a radio frequency identification (RFID) transponder and a method for fabricating the same. The RFID transponder, comprising: a microchip which is arranged to communicating with a reader; a battery which is arranged to provide an electrical power for operating the transponder, and is attached to the microchip by means of a conductive path; an antenna which is arranged to receive and backscatter radio frequency interrogation radiation; and a substrate, on which the microchip, the battery and the antenna are arranged.

Abstract: The present invention relates to an RFID tag comprising a heat-resistant substrate made of a plastic film and capable of withstanding temperatures up to 200° C., an antenna formed on the surface of the substrate, an integrated circuit on a silicon chip electrically connected to the antenna and a joint for attaching the chip to the substrate on that the chip is capable of connecting electrically to the antenna. The joint is made of an anisotropically conductive adhesive capable of withstanding temperatures up to 200° C. and having a thermal expansion coefficient essentially similar to that of the silicon chip.

Abstract: This relates to a label to be attached to a surface, the label comprising a transponder. The label comprises a non-adherent flap which contains the transponder. This also relates to a web comprising a backing web and labels, and to a system comprising a surface and a label.

Abstract: The present invention relates to a method for manufacturing products comprising transponders. The method comprises introducing a web comprising on its surface sequential structural modules comprising an impedance matching element and an integrated circuit electrically connected to the impedance matching element, the structural modules having a first distance between each other; cutting the web in such a manner that the sequential structural modules are separated from each other; attaching the structural modules to a product substrate, the sequential structural modules having a second distance between each other, the second distance being longer than the first distance; and attaching the impedance matching elements to antennas, the impedance matching elements and the antennas forming an electrical connection.

Abstract: The present invention relates to an RFID tag comprising a heat-resistant substrate (11) made of a plastic film and capable of withstanding temperatures up to 200° C., an antenna (1) formed on the surface of the substrate, an integrated circuit on a silicon chip (6) electrically connected to the antenna and a joint for attaching the chip to the substrate so that the chip is capable of connecting electrically to the antenna. The joint is made of an an isotropically conductive adhesive capable of withstanding temperatures up to 200° C. and having a thermal expansion coefficient essentially similar to that of the silicon chip.

Abstract: An RFID transponder is disclosed in which predetermined conductive portions will be removed from the transponder should the transponder be removed from a first object to which it is attached. The transponder has a first response to applied RF before the predetermined portions are removed and a second response after such removal. An RF detector can be used to scan objects with transponders to detect the first or the second response and thereby determine when a transponder has been moved.
