Shield element for mounting on an object
09836689 · 2017-12-05 · ·

A shield element for mounting on an object, in particular a flat object, such as a chip card. The object has a base body, an RFID or NFC transponder, a transponder chip and a coil-shaped transmission antenna connected to the RFID or NFC transponder chip. The shield element has a carrier made of non-conductive material. The carrier has a closed or closable conducting path which, upon mounting the shield element on the object, shields the object from the electromagnetic fields generated by an external reading device and directed at the transmission antenna of the RFID or NFC transponder chip.

Methods and apparatus for preserving privacy in an RFID system

A card comprises an antenna configured to generate and receive radio frequency signals, a chip coupled with the antenna, the chip configured to store sensitive information and communicate the information to an authorized reader via the antenna, and a switching mechanism configured to tune and detune the antenna relative to the chip to enable and disable respectively, the chips ability to communicate the sensitive information via the antenna.

Chip card with on/off mechanisms

Chip cards that are protected from unauthorized access to information and instructions stored in the chip card's chip by unauthorized persons using illicit devices that emulate chip readers to interrogate the chips in chip cards and obtain or download confidential data stored in the chips. The chip cards are disabled when not ready to be used, such that the chips cannot be accessed by illicit devices, thus protecting the chip card owner and/or issuer from potential losses.

RFID tag with antenna de-activation switch

A system, device, and method are disclosed for reducing or eliminating interference between proximate electronic devices. The system, device, and method rely on a switch communicatively disposed between a signal origination device and an antenna. Further, the switch is connected to an electronic device and is operable to receive a signal from the electronic device corresponding to whether the electronic device is in an activated or de-activated state. Additionally, when the electronic device is in an activated state, the switch is operable to open, preventing communication between the signal origination device and the antenna.

Destructible RFID tag

Disclosed is a destructible RFID Tag that may include a far field antenna, a near field loop having an RFID chip, and an attachment adhesive configured to bond the destructible RFID Tag to an object. In at least one nonlimiting example embodiment the far field antenna and the near field loop are inductively coupled in a manner that allows the near field loop to send a long distance signal via the far field loop, and wherein the destructible RFID Tag destructs when the destructible RFID Tag is removed from an object after the attachment adhesive is bonded to the object.

RFID TAG, SYSTEM, AND METHOD FOR TAMPER DETECTION
20200160004 · 2020-05-21 ·

Tamper detection on an article is performed by reading data from an RFID tag having an antenna with segments designed to break apart. The RFID tag is secured to the article in such a way that, when the article is tampered with, the antenna segments will break apart. Detachment would decrease the reading range of the RFID tag. An RFID reader may be used to read the data from the RFID tag. The predefined reading range (Rp) of the RFID tag, with antenna segments intact, is obtained from the data which was read by the RFID reader. The RFID reader obtains the data while located at an actual reading range (Ra) relative to the RFID tag. By comparing Ra with Rp, it is determined whether the antenna is still intact. If Ra<Rp, the antenna is likely to be broken apart, thereby indicating that the article has been tampered with.

RFID tag with anti-tamper assembly

A radio frequency identification (RFID) transponder may include a substrate and a device. The substrate may be in communication with a controller and an antenna, and the antenna is arranged to receive radio frequency signals. A first side surface of the substrate may include a capacitor. The device may be detachably coupled with the substrate via a conductive member positioned between the structure and the capacitor of the substrate, and the conductive member may be within a desired proximity of the capacitor. The structure may be attached to an attachment surface so that an attachment strength between the structure and the attachment surface may be greater than a force required to decouple the structure from the substrate. When the structure is decoupled from the substrate, the conductive member separates from the capacitor, disabling the transponder.
