An RFID label processing system for processing base webs comprises a conveyor device configured to feed a base web along a predetermined conveyor path. The base web includes a sequence of processing segments, with each processing segment forming an RFID label. The processing system further comprises at least two processing modules which are arranged adjacent to the conveyor path, wherein the processing modules are spaced apart by a variable distance. At least one sensor module is configured to determine the position of the processing segments on the base web along the predetermined conveyor path and to output a segment position signal, so that a positioning module that is coupled to at least one of the processing modules and the sensor module may be configured to displace the at least one of the processing modules along the predetermined conveyor path depending on the value of the segment position signal.
