Embodiments of the present disclosure generally relate to systems and methods for providing access to information associated with electronically tagged goods. In one implementation, the system may include at least one processor configured to store tag IDs of a plurality of tags; and receive a pairing between a particular tag ID and a product ID. The at least one processor may also be configured to receive a pairing between the particular tag ID and an authorized entity associated with the particular tag ID; and receive, from a requester, a query including an encrypted tag ID of the particular tag. The at least one processor may also be configured to decrypt the encrypted tag ID; determine if the requester is the authorized entity; fulfill the query, if the requester is the at least one authorized entity; and deny the query if the requester is not the at least one authorized entity.

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 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 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 an antenna configured to receive ambient energy. The tag may also include an energy storage component configured to aggregate and store the received ambient energy. The tag may also include a transmitter electrically connected to the energy storage component and configured to transmit the identification signal.

Embodiments of the present disclosure generally relate to a wireless identification tag configured to collect and store ambient energy for use in delayed transmission, and system and methods for use thereof. In one implementation, the tag may include a receiver for receiving ambient energy; a first capacitor for storing the ambient energy; and a second capacitor for collecting and storing the ambient energy. The second capacitor may have lower capacitance than the first capacitor. The tag may also include an inductor interconnecting the first capacitor and the second capacitor. The tag may also include circuitry configured such that ambient energy received by the receiver is initially stored in the second capacitor and subsequently transferred to and stored in the first capacitor. The tag may also include a transmitter electrically connected to first capacitor, to enable the energy stored in the first capacitor to power the transmitter.

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.
