The invention relates to an identification system for identifying electrically conductive foreign bodies (F) in the region (3) between the primary and secondary winding of an inductive energy transmission system, the identification system likewise having at least one primary coil (LA) and at least one secondary coil (LB) which are intercoupled. At least one primary coil (LA) and/or at least one secondary coil (LB) of the identification system is a constituent part or are constituent parts of at least one electrical resonant circuit (LA-CA; LB-CB) and an electrical source (7) excites at least one resonant circuit (LA-CA). A monitoring device monitors at least one electrical variable on the secondary and/or primary side of the identification system and identifies the foreign body using said measured electrical variable.
