Abstract: In RFID systems employed for loss prevention, an item supplier or an ingress reader writes an ownership code associated with an organization or facility into a tag, indicating that an item to which the tag is attached is associated with the facility and not foreign. At checkout or point-of-sale an authorization reader or mobile device writes a computed code and/or a ticket into the tag indicating that the tagged item is allowed to leave the facility. At point-of-exit an exit reader determines if the tagged item is allowed to leave the facility by verifying the ownership code and the code or ticket. The loss-prevention system may issue an alert or sound an alarm if a facility-associated item is leaving the facility without a proper code or ticket indicating that the item is approved to leave.

Abstract: RFID tags, ICs for RFID tags, and methods are provided. In some embodiments, an RFID tag includes a memory with multiple sections, and a processing block. The processing block may map one of these sections, or another of these sections, for purposes of responding to a first command from an RFID reader. As such, an RFID tag can operate according to the data stored in the section mapped at the time. In some embodiments, a tag can even transition from mapping one of the sections to mapping another of the sections. This can amount to the tag exhibiting alternative behaviors, and permits hiding data on the tag.

Abstract: RFID readers transmit a Quiet Technology (QT) command to RFID tags causing at least one of the tags to transition between a private profile and a public profile. When a tag is inventoried in the private profile, it replies to the reader with contents from its private memory. When a tag is inventoried in the public profile, it replies to the reader with contents from its public memory, where the contents of the public memory may be a subset and/or modified version of the private memory contents, or entirely different altogether. The tag's profile can be switched again by another QT command from the reader, or following a loss of power at the tag. An access password and/or a short-range mechanism may be employed to allow only authorized readers to transition tag profiles or interrogate the private memory contents of tags in the public profile.
