Abstract
The invention relates to a method for determining of at least an order of objects O1,O2 transported by a conveyor 1 along a conveyor path 2, wherein each of the objects O1,O2 carries an assigned transponder T1,T2 having a characterizing code.At least a first radio frequency identification reader R1—having at least a first reader-antenna A1 for generating a first reading field F1—is arranged with respect to the conveyor 1 and built for identifying the transponders T1,T2 of the transported objects O1,O2 passing along or through the first reading field F1. The following steps are performed: reading out the codes of the transponders T1,T2 by the first reader R1 and generating detection-signals as long as the respective transponder T1,T2 is detectable by the first reader R1, saving the detection-signals linked with a time information, deriving a mean first point of time for each detected transponder T1,T2 from the saved detection-signals and the time information linked therewith by an assessment method—wherein the first points of time indicate an estimated discrete point of time for each transponder of passing the first reader R1—and determining the order of the objects O1,O2 on the con…
