Abstract:
A radio frequency (RF) communication device (1, 1′, 10) has data transmission means and data receiving means. The data transmission means comprise load modulating means (3) being adapted to receive a radio frequency carrier signal (CS1, CS2) emitted by another RF communication device (1, 1′, 10) and to modulate the RF carrier signal (CS1, CS2) by means of load modulation in accordance with data to be sent. The data receiving means comprise a RF frequency carrier signal generator (4) being adapted to emit a radio frequency carrier signal (CS1, CS2) and load demodulating means (5) being connected to an emission path (4a) of the radio frequency carrier signal and demodulating the radio frequency carrier signal (CS1, CS2) when it has been load modulated by another RF communication device (1, 1′, 10).
