摘要： The present invention relates to a contactless integrated circuit reader operating by inductive coupling, comprising an antenna circuit for sending an alternating magnetic field, circuits for applying an alternating excitation signal to the antenna circuit and circuits for modulating the amplitude of an antenna signal present in the antenna circuit according to data to be sent. The reader includes circuits for simulating the operation of a contactless integrated circuit, arranged to inhibit the application of the excitation signal to the antenna circuit and to apply a load modulation signal to the antenna circuit when data is to be sent. The load modulation signal is capable of disturbing a magnetic field sent by another contactless integrated circuit reader and of being detected by the other contactless integrated circuit reader.
