Abstract:
An RFID device includes an antenna, a passive RFID communication module and a passive biometric authentication module. The passive RFID communication module is configured to transmit data to an RFID reader without the use of encryption where, the RFID device is configured such that initially power is supplied only to the passive biometric authentication module until the biometric authentication module 120 has verified the identity of a user, whereupon power is supplied to the passive RFID communication module 110 to permit communication, thus the RFID device is thus less vulnerable to sniffing attacks than conventional unencrypted RFID tags because the device will hold its data securely until an authorized biometric identifier is presented to it.
Abstract:
A stretch-activated switch is incorporated in an RFID tag that can be mounted on a stretchable, wearable textile article. The stretch-activated switch can receive a stretch input to place the RFID tag in either an activated or an unactivated state. The stretch input can correspond to a user donning or doffing the stretchable, wearable textile article.
Abstract:
A tag writer, reader and method are disclosed. The tag writer is operable to generate a security identifier during writing of data to the tag, the security identifier being dependent on one or more of the data written, data already on the tag, metadata associated with the data, the tag and/or the writing of the data.
Abstract:
The present disclosure relates generally to methods and system for creating a multiple part peel and reseal label assembly that may include one or more RFID devices for use in providing information to potential end users. The assembly may be provided with a plurality of informational sheets or layers that may be printed with fixed or variable information.
Abstract:
The present invention relates to a device for identifying an electric appliance when said appliance is powered on, including: a current detector coupled with an electric power cable of the electric appliance in order to detect the passage of an electric current in said cable and to generate an electric signal; a voltage generator for converting the electric signal at the output of the current detector into a DC voltage; an RFID circuit making it possible to store identification information, coupled with an antenna suitable for receiving and transmitting signals towards an RFID reader; the device being characterised in that it includes a control circuit coupled with the voltage generator and with the RFID circuit, said control circuit including means for producing an impedance change of the antenna when the DC voltage is applied, the impedance change making it possible to transmit the identification information to the RFID reader.
Abstract:
A system and method for tracking medical articles located in a container includes a hybrid isolated magnetic dipole (“IMD”) probe that provides an activating EM energy RF field having a magnetic near field at least as great as the electric near field, both of which cover the entire interior of the container. The probe comprises a main element having capacitive coupling across at least one slot and spacing above a ground plane to thereby form an isolated electric field and an equally strong or stronger magnetic field that fills the interior of the container to activate RFID tags therein. A dual system is provided for larger containers. A dynamic impedance tuning system controls the probe impedance for increased efficiency in transferring power to the interior of the container. Beam steering is provided with the IMD probe.
Abstract:
A mobile computing device, including: a first memory device having first computer-readable instructions tangibly recorded thereon; a first hardware processor configured to execute the first computer-readable instructions recorded on the first memory device; and an RFID component that includes a transceiver configured to receive a proximity signal from at least one RFID reader when the RFID component is within a predetermined range of the at least one RFID reader, and a second memory device configured to store the proximity signal, wherein the first hardware processor is configured to, upon executing the instructions recorded on the first memory device, control at least one operation of the mobile computing device in accordance with the proximity signal received by the transceiver of the RFID component from the at least one RFID reader.
Abstract:
The present disclosure provides a method and system for inspecting a vehicle. The method comprises: acquiring a unique identity number of an inspected vehicle; carrying out X-ray scanning on the inspected vehicle to acquire an X-ray image of the inspected vehicle; retrieving at least one historical inspected image related to the unique identity number from a historical inspection database; determining, based on one template image selection algorithm selected from multiple template image selection algorithms, one of the at least one historical inspected image as a template image; determining a difference region between the X-ray image and the template image; and presenting the difference region to a user.
Abstract:
A tag writer, reader and method are disclosed. The tag writer is operable to generate a security identifier during writing of data to the tag, the security identifier being dependent on one or more of the data written, data already on the tag, metadata associated with the data, the tag and/or the writing of the data.
Abstract:
The present disclosure relates to efficient near field communication (NFC) tag detection and related methods. In accordance with one example, there is provided a method of communication between a mobile wireless communications device and near field communication (NFC) tags, comprising: polling for NFC devices at a default rate; detecting an NFC tag in response to the polling at the default rate; when the detected NFC tag was previously detected a first threshold number of times within a first threshold duration, polling for NFC devices at a reduced polling rate.
