A method and system is provided for selecting one or more transponders from a plurality of transponders by a base station, in which a random number generated in a given transponder determines a point in time when the transponder in question transmits an identification to the base station. The base station transmits a selection command, then, in order to determine whether at least one transponder is addressed by the selection command, all addressed transponders substantially simultaneously transmit an identification to the base station at a first point in time, and if more than one transponder is addressed, each addressed transponder transmits its identification to the base station at least once more at an additional point in time. The additional point in time being determined by the value of the random number generated or to be generated in the relevant transponder.
