A safety lock () comprising a transponder () and a shackle (). The transponder () comprises an inlay () including an IC () and antenna coupling elements (). The inlay () is arranged in a base member (). The safety lock () further comprises a housing (), wherein the base member () comprises a reduction zone () the mechanical strength of which is reduced compared to portions of the base member () next to said reduction zone (). The reduction zone () is arranged under the IC () and/or the antenna coupling elements () of the inlay (). The force striving the shackle () from the locked state to the open state is arranged to being transmitted to the reduction zone ().

Safety lock

An RFID transponder (), comprising a printable surface (), an antenna element (), an IC (), and a ground plane () arranged under the antenna element (). The ground plane () comprises one or more opening(s) () through said ground plane () for enabling near field communication through the ground plane ().

RFID transponder and RFID transponder web

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.

RFID transponder and a method for fabricating the same

The present invention relates to a radio frequency identification tag which is adapted to work at a frequency between 850 MHz and 950 MHz. The tag may comprise a planar inverted F antenna, a loop antenna, or a dual patch antenna.

Radio frequency identification tag

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&#xb0; 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&#xb0; C. and having a thermal expansion coefficient essentially similar to that of the silicon chip.

RFID tag

Tuning an antenna circuit that includes an inductance of a resonance circuit, and a component having a component impedance. The antenna circuit includes multiple connection areas for connecting the component to the antenna circuit At least two of the multiple of connection areas are part of the resonance circuit. The tuning can be performed by selecting at least one connection area for the component among the at least two of the multiple connection areas

Transponder tuning method and a transponder

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.

Label comprising a transponder and a system comprising a transponder

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.
