摘要： A near field magnetically coupled contactless device, comprises a foldable substrate in the form of a tape; an antenna circuit tuned to a nominal frequency, including an antenna and a capacitor connected to the antenna; a sacrificial impedance connected to the antenna circuit to contribute to the tuning of the antenna circuit to the nominal frequency; and a sacrificial structure comprising a conductive track connecting the sacrificial impedance to the antenna circuit, configured in meanders occupying a region of interest of the substrate such that a piercing of the region of interest severs the conductive track.

摘要： An NFC tag includes a foldable substrate in the form of a tape; an antenna located at a first end of the tape; a capacitor connected to the antenna, located at the first end of the tape; an impedance, in particular a capacitor, located at a second end of the tape; and conductive tracks running along the tape to connect the impedance to the antenna.

摘要： A near field magnetically coupled contactless device includes a foldable substrate in the form of a tape; two metal surfaces located facing each other on opposite sides of the substrate in a region of interest of the substrate, configured such that a piercing of the region of interest causes a permanent short circuit between the two metal surfaces; and a circuit configured to detect a short circuit between the two metal surfaces.

摘要： A near field magnetically coupled anti-counterfeiting tag comprises a control microcircuit configured to implement a basic function and a cryptographic function; a sacrificial conductive track located across a sacrificial area of the tag; and a circuit for detecting continuity of the sacrificial track, cooperating with the microcircuit to implement the basic function without implementing the cryptographic function when the sacrificial track is broken.
