    • A reader device for electronic article surveillance (EAS) is disclosed which includes an exciter; a transmitter, the transmitter operatively coupled to the exciter via a first signal gate; a transmitter antenna operatively coupled to the transmitter; a receiver antenna operatively coupled to a receiver front end; and a signal detector, the receiver front end operatively coupled to the signal detector via a second signal gate, wherein the exciter generates a burst of electromagnetic energy in a pulse or a continuous wave at an operating frequency of a radiofrequency identification (RFID) tag within a read range of the EAS reader such that the energy level of the burst generates a residual or ring-down signal from the RFID tag indicating the presence of the RFID tag without activating the RED functions of the tag. The ring-down signal is read by the EAS reader as an EAS function.

    • An integrated electronic article surveillance (EAS) and radiofrequency identification (RFID) marker is provided which a semiconductor device which may be coupled to an antenna for receiving and retransmitting energy and signals to the antenna. A current receiving front end section of the semiconductor device communicates with at least one other section of the device so more than one function can be implemented upon receiving and retransmitting energy and signals. A first switch is operatively coupled to the front end section such that the functions are entirely but reversibly disabled upon closure of the first switch thereby effecting a reversible EAS function. A second switch is operatively coupled to the front end section such that at least one of the functions is at least partially disabled upon closure of the second switch. RFID functions of the marker are retained upon EAS deactivation.
    • 提供了一种集成的电子物品监视(EAS)和射频识别(RFID)标记,其可以耦合到天线的半导体器件,用于向天线接收和重发能量和信号。 半导体器件的电流接收前端部分与器件的至少一个其他部分通信,因此在接收和重发能量和信号时可以实现多于一个功能。 第一开关可操作地联接到前端部分,使得功能在第一开关闭合时完全可逆地禁用,从而实现可逆的EAS功能。 第二开关可操作地联接到前端部分,使得至少一个功能在第二开关闭合时至少部分地被禁用。 标记的RFID功能在EAS停用时保留。
