A system combining readers for various communication protocols (e.g., RFID transponders and Bluetooth devices) for automated roadway tolling and monitoring is described. Because of the ubiquity of communication devices (e.g., Bluetooth devices), filtering methods are described to narrow received signals (e.g., Bluetooth signals) to a particular monitored traffic lane and to further associate the signal (e.g, Bluetooth signal) with a registered toll tag (e.g., RFID toll tag) associated with a vehicle. The signal strength of the signal (e.g, Bluetooth signal) at each of a plurality of receiver antennas may be used to identify the location of the communication device (e.g., Bluetooth device) that emitted the signal.

Vehicle occupancy data may be set by the user with the client application via a Bluetooth® connection in connection with high occupancy vehicle tolling and express lane incentive programs. The BLEET may be used in a congestion pricing (CP) toll area, wherein the smart phone determines a toll rate based on the location, when triggered by the BLEET, that the BLEET was read by an RFID reader located on a boundary of the CP toll area.

Method and apparatus for testing RFID tags for mass production
A testing system and method for testing glass-mounted RFID tags such as tags mounted on vehicle windows. A testing carrier for use in a test chamber simulates the effect on the tag of the mounting glass. The test chamber and carrier are calibrated by first mounting the tag on the test carrier and making sensitivity measurements and then mounting the tag on glass that is representative of the actual production environment. Comparisons are made between the two measurements and calibration factors are derived to compensate for differences between the actual mounting glass and the test carrier. The test carrier is designed to provide uniform pressure against the tag to minimize any distortions that would alter the sensitivity of the tag.
Distance to a modulated backscatter tag is measured with a RFID reader that measures changes in phase with frequency of modulated backscattered RF signals. Measured distances are linked to a specific tag. The effects of other sources of reflected and interfering signals are mitigated. The techniques eliminate the need for high RF bandwidth used in time-of-flight methods, and may be used with linear, limiting or other types of amplifiers in the reader receiver. Unambiguous distance to a tag may be found using the derivative of phase with RF frequency of the modulated signal backscattered by a tag. The distance to a tag can be measured with an accuracy on the order of a centimeter. The techniques utilize the characteristics of cooperative backscatter tags (transponders, labels, etc.). New readers implement the techniques which may use unmodified tags.

A transponder includes a notch filter to suppress the 1300 MHz at minimal product cost increase. The notch filter utilizes a printed transmission line length adjusted to a correct length. This notch filter will connect to the antenna matching circuit at a junction between the antenna and an ASIC as a shunt component with high impedance (e.g., greater than 500 Ohms) at 915 MHz and low impedance (e.g., less than 10 Ohms) at 1300 MHz. Since the operating impedance of the junction is about 200 ohms, the 915 MHz signal from the antenna will feed the ASIC without any attenuation with a high shunt impedance component, while the 1300 MHz signal will be attenuated significantly by a low shunt impedance component. The transponder is applicable for all types of RFID tags (e.g., passive, semi-passive, active, read only, read-write, read first, tag-talk first) and is well suited for tags operating at radio frequencies, including microwave frequencies (e.g., 902 MHz to 928 MHz) in the U.S.

A tamper resistant electronic tag that wirelessly receives and transmits unique subscriber information to and from a transceiver so that financial transactions can occur quickly and seamlessly. In a preferred embodiment, the tag works in conjunction with a roadway toll booth and is mounted onto a flat interior surface of a vehicle, where it can receive and transmit electronic information to and from a toll booth. That allows a driver to pay the toll fee without having to stop his vehicle. The electronic tag includes a plastic protective card for carrying a circuit. The circuit includes an integrated circuit that is adhesively attached to the protective card. The protective card and circuit are then attached to the flat surface. When the protective card is removed, the integrated circuit is pulled off with the protective card while the rest of the circuit remains attached to the flat surface, thereby severing the circuit, and rendering it inoperable. This prevents the unwanted tampering and unauthorized use of the electronic tag.
In a protocol for preserving the privacy of communications between a RFID reader and a RFID tag, two distinct actions are taken. First, the reader and the tag must be mutually authenticated as being authorized participants in the communications.

A multi-protocol RFID interrogating system employs a synchronization technique (step-lock) for a backscatter RFID system that allows simultaneous operation of closely spaced interrogators. The multi-protocol RFID interrogating system can communicate with backscatter transponders having different output protocols and with active transponders including: Title 21 compliant RFID backscatter transponders; IT2000 RFID backscatter transponders that provide an extended mode capability beyond Title 21; EGOTM RFID backscatter transponders, SEGOTM RFID backscatter transponders; ATA, ISO, ANSI AAR compliant RFID backscatter transponders; and IAG compliant active technology transponders. The system implements a step-lock operation, whereby adjacent interrogators are synchronized to ensure that all downlinks operate within the same time frame and all uplinks operate within the same time frame, to eliminate downlink on uplink interference.
