Abstract: An authenticated RFID system is provided that uses elliptic curve cryptography (ECC) to reduce the signature size and read/write times when compared to traditional public key implementations such as RSA. Either ECDSA or ECPVS can be used to reduce the signature size and ECPVS can be used to hide a portion of the RFID tag that contains sensitive product identifying information. As a result, smaller tags can be used or multiple signatures can be written at different stages in a manufacturing or supply chain. A key management system is used to distribute the verification keys and aggregate signature schemes are also provided for adding multiple signatures to the RFID tags, for example in a supply chain.

Abstract: An RFID reader controlling device based on a plurality of RFID reader protocols receives control instructions for controlling RFID readers from application devices providing services, and confirms RFID reader protocol types corresponding to control instructions to confirm whether communication channels corresponding to RFID reader protocols are generated. Further, the RFID reader controlling device transmits the control instructions to the RFID readers through the communication channels and transmits the control results of the RFID readers corresponding to the control instructions.

Abstract: A communication apparatus includes: a receiving unit which receives reception data transmitted from an external apparatus; an acquiring unit which acquires identification information for identifying the external apparatus which transmits the reception data; and a tag writer which wirelessly write the identification information into a wireless tag.

Abstract: An RFID reader requires significant power supply current, upwards or beyond 0.5 amps. Much of this power is expended to activate the reader's radio frequency transmitter. For example, the reader's transmitter may constantly be active awaiting a RFID tag entering within its electromagnetic field. Sometimes an adequate power source, such as AC mains, is not available to provide continuous operation and instead a battery is powers the reader. This invention detects that a RFID tag is within reader range without using the reader's RF transmitter at full power. As a RFID tag is brought within range of a reader's antenna there is significant mutual inductance coupling between the tag antenna and the reader's antenna and this invention provides a sensitive detector of this mutual inductance. The detection of mutual inductance automatically triggers the reader's transmitter to a higher power which is necessary to fully activate the RFID tag.

Abstract: Passive tags use two antennas with only limited mutual coupling one of which receives a power/clock field and the other of which receives a data signal. An area-reading antenna, or two or more antennas, are deployed to generate the power/clock field, from a base station. The base station, or active tags, or both, generate the data signals from time to time. This topology together with the use of low frequencies permits area reads, and permits small and economical passive tags, and further permits localization of a particular passive tag as being nearby to a particular active tag.

The method includes detecting, via a radio frequency identification (“RFID”) tag, a state of a device that is communicatively coupled to the RFID tag; and providing the device setting via the RFID tag when the state signifies that the device is nonoperational.

Abstract: This invention provides a method and system for inventorying wireless transponders, specifically referred to as RFID transceiver devices. The RFID transceiver devices are certifiable by a recognized standards body, such as EPCglobal, or are compatible with recognized standards but have higher functionality than typical passive RFIDs, and yet are implemented with techniques that lower cost and battery requirements. Backscatter techniques of standard passive RFIDs are used to keep cost and battery requirements low. To provide higher functionality, a microcontroller is used in the RFID, along with a battery, but the clock frequency of the microcontroller is adjusted, based on external input, to minimize battery requirements. In one embodiment, the microcontroller initially has a zero or near zero clock frequency.
