  • Rfid Reading Apparatus and Method
    Publication number: 20090058603
    Abstract: This publication discloses an RFDD reading apparatus (1) and a method for the reading apparatus. The RFID reading apparatus comprises a transmitter (3), which is arranged to feed power to at least one RFED tag (2) in the vicinity of the RFID reading apparatus (1), and a receiver (4) operating on the frequency of the transmitter (3), so that the transmitter (3) and the receiver (4) are in operation simultaneously and the receiver (4) is arranged to receiver through a radio channel (7) a reflected signal of at least one RFDD tag (2) in the vicinity of the reading device. In accordance with the invention, the RFDD reading apparatus (1) comprises additionally means (Z2, 12, 13, 14, 20) for separating the payload signal arriving from the RFDD tag (2) from signals other than those arriving from the RFDD tag (2).
