In a circuit ( 2 ) for a communication partner appliance ( 1 ) designed for contactless communication having two activatable send modes (ABM, PBM), which send modes (ABM, PBM) differ from one another with regard to their energy requirement, a determination stage ( 15 ) is provided, which is designed to determine first energy source information (SI1), which first energy source information (SI1) is characteristic of at least one parameter of at least one energy source ( 11, 12 ) serving to supply the circuit with electrical energy, and a decision stage ( 26 ) is additionally provided, which is designed to form a decision result taking account of the first energy source information (SI1) determined with the determination stage ( 15 ), which decision result influences which send mode (ABM, PBM) is to be activated in the circuit ( 2 ) of the communication appliance ( 1 ).
