    摘要: Systems, software, devices, and methods are described for an RFID reader system to communicate with RFID tags. RF energy encountered in conjunction with using a selected channel is detected. The RF energy can be a signal from an RFID tag. The detected signal is used to adjust a waveform shaping parameter. RF waves can be transmitted from the reader to the RFID tags and RF waves can be backscattered from the RFID tags. At least some of the RF waves transmitted to or backscattered from the RFID tags have a waveform with a shape according to the adjusted waveform shaping parameter.

    摘要: 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.

    摘要: RFID reader systems, readers, components, software and methods cause RFID tags to reply using changed reply timing. In a number of embodiments, this timing change is achieved by causing a custom timing command to be transmitted to a tag. In some embodiments, the changed reply timing affects an amount of delay before a tag backscatters a reply.

    摘要: Interfacing is provided, to a utility of an RFID reader. The utility causes the RFID reader to instruct tags to reply using changed reply timing. The interfacing enables an agent to control the utility, for installing it, configuring it, enabling it, disabling it, or operating it. In a number of embodiments, the tag timing change is achieved by causing a custom timing command to be transmitted to a tag. In some embodiments, the changed reply timing alters the delay before a tag backscatters a reply.

    摘要: RFID readers, computers, and methods are provided for reporting on the authentication of one or more RFID tags associated with a proffered item, while requiring special permissions be cleared before reporting. In some embodiments, a question is input about whether a Declared Password (DP) is regarded as proper for an Item Identifier (II), both of which have been input from the tags. An answer is generated for the question from the reference database, and transmitted to the user. The answer does not reveal an Actual Code that is indeed regarded as proper, unless the user first demonstrates they already know it. Beyond the authentication of the tag, the answer can further indicate the legitimacy of the proffered item, for a supply chain, at a Customs Office, etc.
