Embodiments of the present disclosure generally relate to a wireless identification fraud avoidance system and methods for use thereof. In one implementation, the system may include at least one transmitter configured to transmit a first signal to a plurality of identification tags and to cause the identification tags to transmit a second signal. The system may also include a first, proximate receiver configured to receive the second signal from the identification tags. The system may also include a second, more distant receiver configured to receive a third signal from a tag outside a transmission range of the at least one transmitter. The system may also include at least one processor configured to generate a potential fraud alert when the second receiver receives the third signal.

Embodiments of the present disclosure generally relate to a wireless identification tag with varying ID transmission timing, and system and methods for use thereof. In one implementation, the tag may include at least one transmitter and an energy storage component electrically connected to the at least one transmitter. The energy storage component may be configured to collect and store ambient energy and to power transmission of the at least one transmitter. The tag may also include at least one circuit. The at least one circuit may be configured to cause the at least one transmitter to transmit a sequence of identification signals in non-uniform intervals such that times between identification signal transmissions of three consecutive transmissions vary.

Embodiments of the present disclosure generally relate to a wireless identification tag triggerable by an EAS gate while remaining invisible to the EAS gate, and system and methods for use thereof. In one implementation, the tag may include an antenna tuned to receive energy transmitted in at least one EAS gate frequency range and configured to be non-detectable by the EAS gate. The tag may also include a transmitter configured to send an identification signal and an energy storage component for powering the transmitter. The tag may also include a circuit connected to the antenna. The circuit may be configured to detect energy transmitted from the EAS gate in at least one of the EAS gate frequency ranges, and to cause the transmitter to transmit, to a receiver other than the EAS gate, the identification signal in a frequency outside the EAS gate frequency ranges.

Embodiments of the present disclosure generally relate to a wireless identification tag with a response time that varies as a function of incoming signal frequency and system and methods for use thereof. In one implementation, the tag may include at least one antenna tuned to receive energy transmitted at a first frequency and at a second frequency. The tag may also include at least one transmitter. The tag may also include at least one circuit configured to detect whether energy is received in the first frequency or the second frequency, and to cause the at least one transmitter to transmit an immediate response when the second frequency is detected and to transmit a delayed response when the first frequency is detected.

Embodiments described herein include a chipless patterned conductor, comprising one or more glyphs. Each glyph comprises a disk and a ring structure including at least one ring surrounding the disk. One or more of a spacing between the disk and the at least one ring and a width of the at least one ring is configured to determine a characteristic resonant frequency of the glyph. At least one notch is disposed in at least one of the disk and at least one ring of the ring structure. The at least one notch is configured such that the magnitude of resonances in the glyph are dependent on polarization direction.

Embodiments of the present disclosure generally relate to systems and methods for providing privacy to downstream owners of electronically tagged goods. In one implementation, the system may include at least one processor that may be configured to store IDs for a plurality of tags including at least a first owner ID and a second owner ID for a particular tag; associate first information of the particular tag with the first owner ID at a time when the first owner of the particular tag is recorded as owning the tag; record a transaction transferring ownership of the particular tag from the first owner to a second owner and after the transfer of ownership, associate second information of the particular tag with the second owner ID, and prevent the first owner from accessing the second information.

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.
