摘要： A method and system for exchanging data between one or more RFID readers and one or more EAS system devices in an RFID system using RFID air interface protocol. An RFID system includes one or more EAS system devices in data communication with one or more RFID readers over an interrogation zone. EAS system devices utilize RFID air interface protocol to transmit wireless data signals, which may include alarm event data, to the RFID readers, obviating the need to implement a separate communication infrastructure. The RFID readers may forward the alarm event data to an RFID backscatter enabled host computer for processing the received signals. The host computer may then schedule further interrogation of inventory items at locations where an alarm event has occurred. One or more multiplexers may facilitate the data exchange between RFID readers and the EAS system devices in order to provide an even more robust communication network.

摘要： A method and system for increasing the read range of a security tag by supplying an additional antenna system to the tag in order to provide power to a radio frequency identification (“RFID”) chip without the need to rely solely on power from the RFID reader. The security tag includes an RFID chip and a first antenna circuit coupled to the RFID chip where the first antenna circuit is adapted to decode interrogation signals from an RFID reader. The security tag also includes a second antenna circuit coupled to the RFID chip. The second antenna circuit is adapted to induce power from signals received from at least an alternate power source, such as an EAS transmitter, so that the RFID chip can be powered up and activated during an RFID interrogation round.

摘要： An RFID detection system for determining the location of tagged items within an interrogation zone. The system includes one or more printed circuit boards coupled to each other and placed within a region of the interrogation zone. Each printed circuit board contains an antenna array having one or more antennas where each antenna detects the presence of one or more tagged items within a specific read zone in the region. The printed circuit board also contains a multiplexer coupled to the antenna array, where the antenna array and the multiplexer are provided on a substrate. Upon an interrogation request from an RFID reader, a specific antenna can be activated and selected by the multiplexer and tagged items within the antenna's read zone are interrogated. RF signals containing RF identification information are then transmitted back to the RFID reader where a host computer interprets the signals and determines the location of the identified tagged items.
