Provided is an assembly that includes a first shield part and a second shield part. The first shield part is foldable on the second shield part. Each of the first shield part and the second shield part includes or is connected to at least one closure element, so that the at least one closure element associated with the first shield part is in contact with at least one corresponding closure element associated with the second shield part. The contact allows ensuring an electrical continuity between the first shield part and the second shield part and generating a Faraday cage. Other embodiments disclosed.

In a management system of a game token coin, one RFID tag having a data non-rewritable region and a data rewritable region is imparted to the game token coin. The location relating information of the game token coin is stored in the data rewritable region. The system includes a writer configured to additionally write the location relating information, a reader configured to read the location relating information from a plurality of the game token coins, and a management controller configure to examine the information obtained from the reader. The management controller includes a function that determines whether a history of the location relating information obtained from the reader has no abnormality.

A system for protecting personal data contained on an RFID-enabled device, suitable for use with an RFID system including an RFID reader configured to extract information from an RFID chip associated with the RFID-enabled device, includes a personal data protection system including a personal data protection device configured to prevent reading of the RFID chip associated with an RFID-enabled personal item.

In some examples, a controllable read blocking based radio-frequency identification (RFID) device may include a substrate layer, and a trace formed of a conductive material and disposed on, partially within, or fully within the substrate layer. The controllable read blocking based RFID device may further include a controllable read blocking layer disposed on the substrate layer and the trace and including a fluid disposed in the controllable read blocking layer to selectively block or allow passage of electromagnetic waves to the trace to respectively inhibit or allow communication of a RFID reading device with the controllable read blocking based RFID device.

The apparatus comprises: a pair of panel portions; a hinge portion defining an axis from which each of the panel portions extends, the hinge portion being coupled to each of the panel portions and adapted to permit pivotal movement of the panel portions relative to one another about the axis between a closed position wherein the panels overlay one another one another and an open position wherein the panels extend away from one another; a near field communication tag coupled to one of the panel portions; and a shield defined by RF blocking material coupled to the other of the panel portions. The tag and shield are positioned and adapted such that: the tag can be activated by the reader when the panels are in the open position; and the shield isolates the tag from the reader when the panels are in the closed position.

The invention relates to a contactless chip card intended to communicate with a chip card reader operating at a resonant frequency F.sub.0. The chip card includes a booster antenna provided with an inductive main antenna U and with an inductive concentrator antenna L.sub.2, which antennae are connected in series or parallel with a capacitor C, wherein the inductances of L.sub.1 and L.sub.2 and the capacitance of C are chosen on the one hand to obtain a resonant frequency F.sub.0 that is far enough from the frequency of the signal emitted by the reader to limit radiofrequency communication with the reader, and on the other hand so that the connection in parallel of a predetermined capacitance C.sub.d brings the resonant frequency of the card into the vicinity of said frequency F.sub.0 of the signal emitted by said reader.
