Embodiments of the present disclosure generally relate to systems, methods, and computer readable media containing instructions for causing simultaneous triggering and sequential reading of a plurality of tags. In one implementation, the instructions may include displaying an activatable element on a graphical user interface for activating a 2.4 GHz transmitter. The instructions may also include activating the transmitter to cause each of a plurality of tags to send a unique tag ID to a receiver. The instructions may also include reading a first group of tag IDs during a first time interval; recording first information associated with the first group; maintaining activation of the transmitter to cause transmission of at least some of the tag IDs of the first group along with the unique tag IDs of a second group of tag IDs to the receiver; and recording second information associated with the second group.

Embodiments of the present disclosure generally relate to a wireless identification tag for association with a product to enable product self-identification and system and methods for use thereof. In one implementation, the tag may include at least one antenna tuned to receive energy transmitted at one or more frequencies within certain frequency bands. The tag may also include at least one transmitter that may be configured to send at least one identification signal. The tag may also include at least one circuit. The at least one circuit may be configured to detect whether energy is received in a certain frequency band, and to cause the at least one transmitter to operate in a mode corresponding to the certain frequency band.

Embodiments of the present disclosure generally relate to systems and methods for protecting against distribution of counterfeit products. In one implementation, the system may include at least one processor configured to store tag IDs of electronic tags associated with products and at least one identity of a first entity associated with a specific product. The processor may also be configured to receive, on behalf of a prospective subsequent custodian of the specific product, an encrypted tag ID associated with the specific product and a query associated with the identity. The processor may also be configured to decrypt the encrypted tag ID; check if the identity identified in the query corresponds to an entity in the ownership history; and cause a transmission based on the identification of the at least one identity.

Embodiments of the present disclosure generally relate to an appliance for holding electronically tagged products and for recording an association between the tagged products and the appliance, and system and methods for use thereof. In one implementation, the appliance may include a housing defining a cavity for retaining the electronically tagged products. The appliance may also include an exciter integrated with the housing and configured to trigger tags of the products to cause the tag of each product to transmit a unique tag ID. The appliance may also include a receiver for receiving transmission of each unique tag ID. The appliance may also include a communicator for outputting indications of identities of electronically tagged products retained in the cavity.

Embodiments of the present disclosure generally relate to a wireless identification tag with varying identity, and system and methods for use thereof. In one implementation, the tag may include at least one transmitter configured to transmit a tag ID. The tag may also include at least one circuit. The at least one circuit may be configured to receive a first trigger at a first time and generate in a quasi-random manner a first decipherable ID uniquely identifying the tag, and cause the at least one transmitter to transmit the first decipherable ID. The at least one circuit may also be configured to receive a second trigger at a second time and generate in a quasi-random manner a second decipherable ID different from the first decipherable ID and uniquely identifying the tag, and cause the at least one transmitter to transmit the second decipherable ID.

Embodiments of the present disclosure generally relate to a wireless identification tag configured to harvest ambient energy and transmit an identification signal intermittently, and system and methods for use thereof. In one implementation, the tag may include a transmitter configured to transmit a first signal to a first receiver in a first frequency, and to transmit a second signal to a second receiver in the first frequency. The tag may also include an energy storage component configured for collecting and storing ambient energy and for powering transmission of the transmitter. The tag may also include a circuit configured to monitor energy stored in the energy storage component, and to prevent the transmitter from transmitting the first signal to the first receiver when the energy stored in the energy storage component is insufficient to transmit the second signal to the second receiver.

A method of detecting a metal object in a detection zone between a transmitting antenna (101) and a receiving antenna (102) installed in proximity of a revolving door (110), the method comprising: in real time: demodulating a signal received via the receiving antenna (102) to provide a first signal (y; 501); filtering the first signal (y; 501) by a first adaptive notch filter (201) to suppress at least a fundamental tone or a fundamental tone and one or more harmonic tones of the fundamental tone in a filtered signal (e; 502); and processing the filtered signal (e; 502) to detect an impulse (504), and while the impulse develops, computing a feature value of the impulse and determining whether the feature value exceeds a threshold. In case the feature value exceeds the threshold, setting a first alarm detector. In this way a so-called booster bag can be reliably detected the moment it passes the detection zone.

The present invention describes a tag comprising a magnetic element in the form of a microwire of 80-250 microns with giant magnetoimpedance which, when joined to an object, allows for the wireless detection of same by modulating the reflectivity of the microwire. Detection is performed by using a system that emits an electromagnetic wave that has a frequency between 1 and 20 GHz and a low frequency magnetic field (0.01-50 Hz), and detects the modulation of the reflectivity of the microwire. Thus, objects at distances greater than 1 m can be detected.

Systems and methods for operating an Electronic Article Surveillance (EAS) system. The methods comprise: detecting movement of a plurality of security tags in a facility using Radio Frequency Identification (RFID); identifying which security tags of the plurality of security tags are moving towards an exit of the facility or are in a surveillance zone; determining a number of the identified security tags that are coupled to unsold objects; comparing the number to a threshold value; and causing the EAS system to issue an alarm when the number is greater than or equal to the threshold value.

Systems and methods for operating a pedestal of an Electronic Article Surveillance (EAS) system. The methods comprise: capturing at least one first image or video by a camera coupled to the pedestal; analyzing the at least one first image or video to detect a person's presence and determine the person's location relative to the camera; determining a first beam pointing direction for the pedestal based on results of the analysis of the at least one first image or video; and steering a read beam of the pedestal in accordance with the first beam pointing direction so that a main lobe of the pedestal's antenna field pattern covers a first area of an interrogation zone.
