Abstract
Contactless transmission of data for a number of information carriers uses a reader connected alternately at time intervals with a number of antennas, to send polling signals to information carriers and/or to receive information signals from the information carriers. If the connection between the reader and an antenna initially connected with the reader is broken, then simultaneously this antenna that has been disconnected from the reader is connected with at least one further energy source transmitter, in order to continue to supply the information carriers that are in the energy field of this antenna and which have already been read out and/or switched to 'silent' or 'inactive' with energy to maintain this state.
