The invention relates to a method for determining of at least an order of objects O,Otransported by a conveyoralong a conveyor path, wherein each of the objects O,Ocarries an assigned transponder T,Thaving a characterizing code. At least a first radio frequency identification reader R&#x2014;having at least a first reader-antenna Afor generating a first reading field F&#x2014;is arranged with respect to the conveyorand built for identifying the transponders T,Tof the transported objects O,Opassing along or through the first reading field F The following steps are performed: reading out the codes of the transponders T,Tby the first reader Rand generating detection-signals as long as the respective transponder T,Tis detectable by the first reader R, saving the detection-signals linked with a time information, deriving a mean first point of time for each detected transponder T,Tfrom the saved detection-signals and the time information linked therewith by an assessment method&#x2014;wherein the first points of time indicate an estimated discrete point of time for each transponder of passing the first reader R&#x2014;and determining the order of the objects O,Oon the conveyoraccording to the first points of time of each transponder T,T

Method and device for determining of an order of conveyed objects

A radio frequency identification (RFID) system is described, including a low frequency read-write device (B) comprising an antenna (B) connected to a transceiver (B), for receiving/transmitting low RF waves from/to an RFID tag (B), and a decoder (B) for decoding said low RF waves into digital data (dig-B); an host computer () is intended to be connected to the low frequency read-write device (B) for processing digital data (dig-B). The RFID system further includes a high frequency read-write device (A), comprising an antenna (A) connected to a transceiver (A), for receiving/transmitting high RF waves from/to an RFID tag (A), and a decoder (A) for decoding said high RF waves into digital data (dig-A); the high frequency read-write device is connected to a low frequency read-write device (B) and to an host computer () respectively through a driver connection () and an host connection (). A bundle interface (ITF), receives digital data (dig-A, dig-B) through the driver connection () while a flow controller (SW) drives the flow of such digital data (dig-A, dig-B) through host connection () and towards the host computer ().
