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.

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 secure wireless data device is disclosed and configured as at least one of a passive, semi-passive, or active RFID or NFC enabled device. In at least one embodiment, the data device provides a memory, an antenna and an at least one access sensor. The memory is configured for storing select wireless data therein. The antenna is in selective wireless communication with a compatible reader. The at least one access sensor is configured for automatically switching between an enabled state—wherein the wireless data is capable of being accessed by the reader—and a disabled state—wherein the wireless data is prevented from being accessed by the reader—based on an at least one measurable physical parameter that is detectable by the at least one access sensor.

A radio frequency identification (RFID) switch tag is disclosed. This RFID switch tag includes a base component having an ultra-high frequency (UHF) booster, and a detachable component having at least one UHF RFID module and a high frequency (HF) RFID module. In some embodiments, the detachable component is positioned in close proximity to the base component in a first configuration of the RFID switch tag such that the at least one UHF RFID module is sufficiently coupled to the UHF booster in the base component to form an UHF RFID system having a desired performance. The detachable component can also be separated from the base component to obtain a second configuration of the RFID switch tag, and the HF RFID module remains functional within the detached detachable component so that the detachable component can be used as a standalone HF RFID tag.

A wireless signal device is provided. The wireless signal device includes a device body, a fastening belt, a wireless signal module and a switch unit. The device body includes a through hole. A fixed end of the fastening belt is affixed to the device body, and a free end of the fastening belt is adapted to be inserted into the through hole. The wireless signal module is disposed in the device body. The switch unit is disposed in the device body, wherein in a signal transmission mode, the fastening belt passes through the through hole, and the switch unit is pressed by the fastening belt to activate the wireless signal module.

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.

A payment card (e.g., credit and/or debit card) or other device (e.g., mobile telephone) is provided with a magnetic emulator operable to communicate data to a magnetic stripe read-head. Gift cards may be inputted by a user into such a payment card or other device such that a user can combine gift cards. Similarly, a user be provided with a global payment account that can be utilized in multiple countries that have different standards for formatting data. A user may be provided with a default country (e.g., United States) but may have a way to select that the user is in a different country (e.g., Japan). Accordingly, a user may select that a Japanese data structure be transmitted through a magnetic stripe reader when the user is in Japan.

The present disclosure provides various examples of a self-declaring wireless device installed on a vehicle operable to automatically detect, determine and declare occupancy information of the vehicle traveling on a restricted traffic lane to an electronic toll collection (ETC) system. According to one aspect, a process for performing self-declaration by a vehicle traveling on a restricted traffic lane includes the steps of: receiving sensor data collected by one or more sensors installed on the vehicle; determining occupancy data of the vehicle based on the received sensor data; and controlling a wireless transceiver installed on the vehicle to communicate with an electronic toll collection (ETC) system associated with the restricted traffic lane based on the determined occupancy data.

A tag is provided that includes a battery having a printed anode and cathode. A printed circuit connection layer is formed in one of the anode or the cathode. A printed antenna is formed in one of the anode or the cathode. A low-power transmitter coupled to the circuit connection layer.

Systems and methods involving biometric authentication of transaction cards including aspects of exception handling, deactivation and other features are disclosed. In one embodiment, an exemplary computer-implemented method may comprise generating a first user interface having one or more interactive UI elements that enable a card owner to manage a plurality of features associated with a transaction card, and determining, if a biometric-activated control is enabled and the vendor is not excluded from the biometric-activated control, whether the transaction card is biometrically-active. Further, the interactive UI elements may include elements such as a first UI element that is configured to allow the card owner to enable a biometric-activated control of the transaction card, and/or a second UI element that is configured to allow the card owner to exclude one or more vendors from the biometric-activated control.
