An apparatus for encoding RF transponders comprising: - a conveyor arranged and adapted to feed RF transponders past a plurality of processing stations in a continuous motion; - a first processing station arranged and adapted to identify respective RF transponders passing by it; and - a second processing station having at least a first RF antenna, wherein -- the first RF antenna has a transmitting area arranged and configured to simultaneously detect a plurality of the RF transponders passed by the conveyor at the second processing station, -- the second processing station is designed to address the RF transponders previously identified by the first processing station with the first RF antenna and subsequently, if an addressing of a respective previously identified RF transponder was successful, to select the respective addressed RF transponder detected by the transmission range of the first RF antenna for the transmission of coding data, and -- transmitting coding data to the selected RF transponder, the transmitted coding data being determined as a function of an identification of the selected RF transponder by the first processing station, characterized in that said second processing station is further adapted, in the event of an unsuccessful addressing of a first previously identified RF transponder, to immediately proceed with the addressing of a further identified RF transponder following said first identified RF transponder and to encode said further identified RF transponder, provided that the addressing of said further identified RF transponder was successful, and, after completion of the encoding of said further identified RF transponder, to again address said first identified RF transponder. - a conveyor arranged and adapted to feed RF transponders past a plurality of processing stations in a continuous motion; - a first processing station arranged and adapted to identify respective RF transponders passing by it; and - a second processing station having at least a first RF antenna, wherein -- the first RF antenna has a transmitting area arranged and configured to simultaneously detect a plurality of the RF transponders passed by the conveyor at the second processing station, -- the second processing station is designed to address the RF transponders previously identified by the first processing station with the first RF antenna and subsequently, if an addressing of a respective previously identified RF transponder was successful, to select the respective addressed RF transponder detected by the transmission range of the first RF antenna for the transmission of coding data, and -- transmitting coding data to the selected RF transponder, the transmitted coding data being determined as a function of an identification of the selected RF transponder by the first processing station, -- the first RF antenna has a transmitting area arranged and configured to simultaneously detect a plurality of the RF transponders passed by the conveyor at the second processing station, -- the second processing station is designed to address the RF transponders previously identified by the first processing station with the first RF antenna and subsequently, if an addressing of a respective previously identified RF transponder was successful, to select the respective addressed RF transponder detected by the transmission range of the first RF antenna for the transmission of coding data, and -- transmitting coding data to the selected RF transponder, the transmitted coding data being determined as a function of an identification of the selected RF transponder by the first processing station,
