  • Patent number: 9000924
    Abstract: An RFID device includes a first, relatively permanent portion and a second alterable or inactivatable portion. Upon the occurrence of some predetermined event, the second portion and/or its coupling to the first portion is physically altered, inactivating it. The first portion may itself be an antennaless RFID device that may be read at short range, and the second portion may be an antenna that, when coupled to the first portion, substantially increases the range at which the first portion may be read. The second portion may be configured to be altered or inactivated by any of a variety of predetermined events, such as involving physical, chemical or electrical forces, performed either on the RFID device, or upon an object to which the RFID device is coupled.

  • Patent number: 8985467
    Abstract: A permanently deactivatable security tag and method to create a permanently deactivatable security tag to eliminate tag pollution caused by reactivated tags reentering a store premises and setting off false alarms. The security tag includes a frangible conductive portion that fractures due to stress applied on the frangible conductive portion from a hardened substrate located on the tag. The hardened substrate induces stress to the frangible conductive portion located adjacent to the edge of the hardened substrate as the tag is flexed and bent. The fracture of the frangible conductive portion of the tag results in a shifting and/or disabling of the predetermined frequency of the security tag.

  • Patent number: 8933784
    Abstract: Provided are an RF powder particle, an RF powder, and an RF powder-containing base that can make it difficult to fabricate, for example, forged documents or forged bank notes with respect to sheet-like objects having high proprietary values, such as bank notes, and that allow necessary information to be stored in each of the large number of particles which are each provided with a tank circuit having a predetermined resonant frequency. The RF powder particle includes a coil 24 (inductance element) as a magnetic filed coupling element and a condenser 25 (capacitance element) connected to the both ends of the coil on an insulating surface of a substrate 22 and is configured so as to form a tank circuit 31 by the inductance element and the capacitance element. The tank circuit 31 functions as a circuit in a resonance state or in a non-resonance state in accordance with conditions in response to a high-frequency magnetic field from outside.

  • Patent number: 8917165
    Abstract: Systems, methods and computer program products for detecting and re-personalizing are provided herein. In an embodiment, the invention operates by obtaining an ID (i.e., an identification, such as a Dynamic Unique Identifier) from a RFID tag, generating a new ID, and writing the new ID to the RFID tag. The ID read from the tag is used to lookup a subject's record in a database. If the write of the new ID to the tag is verified, then database changes are committed to link the new ID to the subject. In an alternative embodiment, the invention operates by obtaining data from a memory of a RFID tag, wherein the memory has a first partition and a second partition, generating a new ID, and writing the new ID to either of the first partition or the second partition of the RFID tag. If such write is verified, then the new ID is written to the other partition of the RFID tag. The data from the tag is used to lookup a subject's record in a database.

  • Patent number: 8836512
    Abstract: The antenna of an RFID tag is automatically tuned by controlling both the real and imaginary components impedance “seen” by the antenna. The real component (resistive) is controlled by controlling a tap of a charge pump circuit of the tag. The imaginary (reactive) component is controlled by connecting one or more reactive elements of an antenna tuning circuit to the antenna. The real component is controlled by a first digital control loop that automatically activates successive taps on a charge pump of the RFID tag which effectively controls the resistance seen by the antenna. A second digital control loop controls the connection of the various reactive components.
