    Abstract: It is proposed a method for performing electromagnetic induction communication consisting in transmitting modulation data to a first communication device (RD) from a second communication device (TED), said method comprising:—Coupling a first antenna (AR) of a the first communication device (RD) and a second antenna of the second communication device (TED),—Generating a magnetic field by supplying a first current (i1) through this first antenna,—Modulating the magnetic field according to the modulation data; Wherein the first current (i1) is regulated so as to be substantially constant, by introducing a regulating current (iR) which is function of the magnetic field, and wherein the first communication device (RD) determines the modulation data (TXMOD) from the regulating current (iR).
