A transaction card may determine to initiate a mode associated with the transaction card. The mode may be related to locating the transaction card. The mode may be associated with outputting a first signal. The transaction card may determine a manner in which to configure the mode based on a set of parameters. The set of parameters may include a power level of the transaction card, or a strength of a second signal associated with a connection between the transaction card and a device associated with the transaction card. The transaction card may initiate the mode after configuring the mode. The transaction card may determine to terminate the mode based on an indication that the transaction card has been located.

A dual communication frequency RFID circuit includes a logic unit for processing data signals received or transmitted at a first frequency by a first antenna or at a second frequency by a second antenna, and a unit for managing the state of a tamper loop linked to the integrated circuit by two connection terminals. The management unit includes a first low-pass filter linked to a first connection terminal, a second low-pass filter linked to a second connection terminal, a current source for supplying a current through the first low-pass filter, a switch linked at the output of the second low-pass filter, and a first inverter connected between the current source and the first low-pass filter for supplying an output signal for the state of the tamper loop to the logic unit.

The present invention concerns a smart tag for attachment to an object. The smart tag comprises an electronic system for contactless communication, a support to which at least part of the electronic system is fixed and at least one destruction component means configured to act on at least one element of the electronic system, when the smart tag is removed from said object, to demolish said at least one element of the electronic system. In at least one embodiment, the destruction component may be a demolisher movably mounted to pass through said support from a first position on one side of the support to a second position on the other side of the support.

A dynamic transaction card that is manufactured using conductive plastic jumpers that will dissolve when in contact with a solvent used to tamper with the dynamic transaction card. Internal components of a dynamic transaction card may be manufactured using a synthetic or semi-synthetic organic material, such as, for example, plastics. These materials may be conductive to provide functionality to a dynamic transaction card, such as a connection between an integrated circuit and other card components such that when the materials dissolve, the connections are broken and the dynamic transaction card may be inactive due to the loss of various connections.

An integrated circuit chip and a method for protecting the integrated circuit chip against physical and/or electrical alterations are disclosed. The chip comprises at least one semiconductor layer including semiconductor components and conductive tracks, at least one layer formed by a first type of conductive tracks extending over all or part of a surface of the chip and at least one second type of conductive track connected to at least one detection circuit configured to detect an alteration of the at least one second type of conductive track. The chip is characterized in that the at least one first type of conductive track is mixed within the at least one second type of conductive track, the material and the layout of at least one second type of conductive track being indiscernible, by an observation device, from the material and the layout of the at least one first type of conductive track.

A labeling set for marking a pharmaceutical vessel including a body having a peripheral surface and a removable closure includes: a three-dimensional molded attachment, a label for sticking on the outer vessel circumference to be marked, and an RFID transponder for electronic identification of the vessel and/or contents. The attachment is mountable and/or positionable on the vessel in a predefined relative position and has a circumferential wall with an outer circumferential surface which is intended as an additional labelable and/or electronically identifiable outer wall and/or outer surface and whose radius, outer circumference and/or wall course is selected in accordance with the radius, outer circumference and/or wall course of the vessel circumferential surface. The label and/or the RFID transponder sticks over and/or covers both a circumferential surface, formed in accordance with the vessel body outer circumference, and the attachment circumferential surface at least in regions and/or to secure the vessel attachment to the vessel.

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.

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.
