The invention relates to electronic communications, in particular to data transmission by inductive method transmitting, digital data contactless transmission digital data from digital data contactless transmission device to receiver, e.g. magnetic stripe card readout device. A method for digital data inductive transmission consists in that normalized radiant power is controlled under conditions of polarity change by quick switching polarity of supply voltage applied to emitter inductance with simultaneous current amplification in the radiator inductance providing the polarization of magnetic radiator head signal in the radiator inductance at parallel position of axes of emitting and detecting inductances. While transmitting data from the computing system as computer, mobile telephone, smartphone, tablet computer and other electronic devices, axis of radiator inductance is arranged in parallel to magnetic stripe card receiver slot at distance up to 15 cm. |
