A magnetic stripe may be provided along the second main side of the body, wherein the magnetic stripe is located on the second section, wherein the magnetic stripe extends parallel to the insertion end perimeter when the first and second sections are in a first configuration, and wherein the magnetic stripe extends perpendicular to the insertion end perimeter when the first and second sections are in a second configuration.

A system for detecting placement or misplacement of an object includes a wireless tag; a first electronic device (“FED”) associated with the tag to automatically detect signals from the tag, determine a position of the FED, transmit the position and status to an external electronic device or network (“EED”) in response to the status indicating that the tag and the FED are within a predetermined range, and transmit the position and status to the EED in response to the status indicating that the tag and the FED are outside of the predetermined range; and a second electronic device (“SED”) that is unassociated with the tag to automatically detect signals from the tag, determine a position of the SED, determine an identifier for the tag using the signals, and transmit the position of the SED and the identifier to the EED.

An electronic payment card includes a payment card substrate having opposed top and bottom faces. An EMV chip is disposed at a location on one of the top and bottom faces of the payment card substrate. The EMV chip is a donor EMV chip removed from a donor electronic payment card on which the donor EMV chip was previously disposed.

An insert assembly, insertable in a handpiece of a medical device, has an insert having an insert metal tang, a ferromagnetic layer in contact with the insert metal tang, a dielectric layer in contact with the ferromagnetic layer, an insert antenna in contact with the dielectric layer, having an insert antenna metal element and configured to receive and transmit electromagnetic fields, and an identification chip operatively connected to the insert antenna and configured to transmit information about the insert assembly. The ferromagnetic layer reduces or cancels attenuation and/or distortion phenomena of an electromagnetic field caused by parasitic effects due to interaction of a transmitted or received electromagnetic field with metal parts of the insert metal tang, liquids present in the insert, and the insert antenna metal element. The ferromagnetic layer dielectric layer and insert antenna form a transceiver device putting the identification chip in communication with a handpiece antenna.

A transaction or identification card has a width, a length, and at least one planar surface extending across the width and length. The card includes a dynamic feature including an actuator having an inactivated position and an activated position, wherein the inactivated position has at least one reversible difference from the activated position relative to the planar surface of the card.

Example embodiments of systems and methods for card production are provided. A card may include processing circuitry including a chip and memory. The card may include one or more antennas in communication with the chip. The card may include a first layer of material aligned within a perimeter of the card via laminate encapsulation. The first layer of material may comprise a non-rectangular shape. The first layer of material may be offset with a shape of the card. The first layer of material may be in communication with the chip. The first layer of material may comprise at least one selected from the group of steel, tungsten, titanium, or any combination thereof. The card may be compliant with one or more form factors.

An integrated circuit, a wireless communication card and a wiring structure of an identification mark are provided. The integrated circuit includes a power supply wiring, a ground wiring and at least one identification mark pattern. Each identification mark pattern has a first conductive wiring and a second conductive wiring that overlap each other, wherein the first conductive wiring is electrically connected to the power wiring, and the second conductive wiring is electrically connected to the ground wiring.

Flexible, stretchable RFID tags are formed by a pocket that is formed from one or more substrates and layers of adhesive, and an electronic circuit that is located within this pocket. The RFID tags can include a stretchable substrate and an electronic circuit attached to the stretchable substrate by one or a finite number of discrete spaced apart attachment locations. When the pocket is formed by relatively thick adhesive layers adhering together one or more flexible substrates to form an internal cavity, the electronic circuit is located within this cavity and either is not adhered to any of the substrates of the cavity, and is free to move about within the cavity, or the electronic circuit can be attached to a substrate by a thin layer of adhesive.

A wireless user authentication system uses an AIDC device and a wireless reader to verify the identity of an individual. The AIDC device is a key fob that contains the user's credentials. The wireless reader is a device that wirelessly interrogates the AIDC device to ascertain the user's credentials. The wireless reader has a casing an interface window, a component cavity, a control panel, multiple antenna spacers, an antenna, and a processing unit. The casing is an enclosure that houses the components of the wireless reader within the component cavity. The interface window is hole that enables the user to access the control panel. the antenna spacers are rigid beams that retain the processing unit in a position that is offset from the control panel. Additionally, the antenna is wound around the antenna spacers and retained in a configuration that facilitates wirelessly communicating with the AIDC device.

An RF system is provided that includes an RFID card and a reader-writer device. The RFID card includes a substrate, an RFIC element, an antenna coil, and a deformation sensor. The reader-writer device and the RFID card transmit and receive predetermined information between an antenna coil of the RFID card and an antenna coil of the reader-writer device through a magnetic field. The RFIC element transmits the first signal via the antenna coil when the deformation sensor does not detect bending deformation of the substrate, and the RFIC element transmits the second signal via the antenna coil when the deformation sensor detects the bending deformation of the substrate.
