wherein the first RFID antenna is placed in an input region, and the second RFID antenna is placed in an output region of a storage track of the live storage system, in order to register the object or the group of objects on the basis of the code of the RFID transponder,

wherein the object or the group of objects are held in the input region by a holding device until the object or the group of objects are identified by means of the code of the RFID transponder, and

wherein the holding device comprises a magnet.

20. The RFID communications system according to claim 19 , wherein the RFID communications system further comprises at least one presence sensor that registers the presence of an object or a group of objects in the input and/or output region of the storage track.

21. The RFID communications system according to claim 20 , wherein the at least one presence sensor comprises a first presence sensor placed in the input region and/or a second presence sensor placed in the output region of the storage track of the live storage system.

22. The RFID communications system according to claim 21 , wherein the RFID antennas activate a reading mode for registering the RFID transponder only when the presence sensors report a change.
