Disclosed are combination radio frequency identification (RFID) and electronic article surveillance (EAS) tags and methods of producing such tags using a converting machine. The method is characterized by feeding a first roll carrying first type inlays and a second roll carrying second type inlays into a converting machine; and, transferring, using the converting machine, the first type inlays to a surface of the second type inlays, thereby forming a two-layer tape carrying pairs of first and second type inlays, each of the pairs comprising an RFID inlay and an EAS inlay, wherein there is no overlap of an RFID antenna element of each RFID inlay and an EAS antenna element of a paired EAS inlay, and wherein the RFID inlay and the EAS inlay of each pair are functionally independent.

A security tag assembly for placing around a boot, including a circuit board having a processor, and one or more wires electrically connected to the circuit board that form a first opening and a second opening. The first and second openings are respectively configured to receive first and second components of the boot. The assembly further includes a tension switch connected to the one or more wires and having a closed position corresponding to a first tension level on the one or more wires and an open position corresponding to a second tension level on the one or more wires, wherein the second tension level is greater than the first tension level. Further, the processor is configured to monitor whether the tension switch is in at least the open position, wherein the processor is configured to trigger an alarm in response to the switch being in the open position.

Disclosures relate to a sensor system and arrangements having different sized removable spacers. The spacers may be mixed and matched as needed or desired to compensate for misalignment conditions. Further, different spacer combinations and adjustments may be guided by a security management computing device. Variations in configurations of mounting surfaces, such as door and window assemblies, may be accommodated. Alignment of a transmitter or a receiving device, e.g., a magnetic device, with respect to a transmitter or receiving device despite misalignment of the components due to, for example, uneven surfaces of a door or a window, or a respective frame may be achieved.

RFID devices for use in electronic surveillance article (“EAS”) systems may be differently configured, resulting in different performance at the operating frequency or range of frequencies of an EAS system. The performance of differently configured RFID devices may be converged or rendered substantially similar by testing the performance of such RFID devices in a range of frequencies. At least one of the RFID devices is reconfigured to converge the performance of the RFID devices in the range of frequencies if the performance of the RFID devices is not sufficiently similar. This may include changing the configuration of an antenna, an RFID chip, and/or a non-functional component of an RFID device and/or the location in which an RFID device is associated to an article. Differently configured RFID devices may all be manufactured from the same initial configuration, with different RFID devices being differently processed before incorporation in an EAS system.

An anti-tamper device combining a RFID component and an article surveillance or security component with a visual indicator. The article surveillance or security component is operatively coupled to a display so that an interruption of the RFID component is visibly indicated by the display. The visual indicator moves between a first state indicating a lack of tampering, and a second state indicating tampering without the need for a battery or external power source.

Described is a security sensor comprising two or more sub-sensors for use in a variety of installations where different magnetic fields may be experienced by the security sensor as a result of the variety of installations. One of the sub-sensors may have a low magnetic sensitivity while the other sub-sensor may have a much higher sensitivity to magnetic fields. In operation, one or both sub-sensors are used to determine if a door or a window has been opened.

Improved systems and techniques are disclosed for controlling the security states of anti theft security systems such as product display assemblies using security fobs. The tasks relating to fob authentication are offloaded to a computer system, and these authentications can be based on identifiers for the different security fobs. The computer system can maintain a list of identifiers for authorized security fobs that is easily updated when new security fobs are added to or existing security fobs are de-authorized from the system.

A anti-theft device with a remote alarm feature is provided. The device is configured to attach to an item of retail merchandise and detect when a predetermined motion and light condition are met which together are indicative of a potential retail theft. Upon detection, the device is configured to generate a local alarm, and send a radio frequency to a remote device to generate an alarm at the remote device.

Systems and methods for detecting a presence of a target such as a vehicle, an animal, a person, or another object in a monitored area without the use of sensors, are provided. Multiple RF field anomaly detection nodes may be spaced through the monitored area and connected, such as in a mesh network. The RF field anomaly detection nodes may include radio transceivers that communicate with one another and which monitor a signal strength of received signals. The nodes may compare the signal strengths to expected strength values. As a target enters a portion of the monitored area, the dielectric properties of the target cause at least one signal strength of at least one received signal to change. The RF field anomaly detection nodes may detect this change and trigger a further action or human readable alert corresponding to the presence of the target.

A system determines an electronic product code (EPC) and a checksum read from a radio-frequency identification (RFID) tag. The system calculates a new checksum based on the EPC and a retailer-specific number associated with a retailer that owns one or more RFID tags. The system compares the new checksum with the checksum read from the RFID tag, and determines whether the RFID tag is owned by the retailer based on whether the new checksum matches the checksum read from the RFID tag.
