SYSTEM FOR DIGITAL DATA TRANSMISSION BY INDUCTIVE METHOD

摘要

A system for digital data transmission by inductive method comprises a device for digital data transmission by inductive method (13) to receiver (14), e.g. to POS-terminal for carrying out transactions, computing systems (12), and device for connection (4) to mentioned systems. The device for digital data transmission by inductive method (13) comprises a transmitter driver (6) and inductor made as transmitter inductance (2). The system comprises a waveform synthesizer (5) comprising real time computing microsystem made as a microcomputer. The device for digital data transmission by inductive method (13) is capable of safe and reliable digital data transmitting from transmitter inductance (2) to receiver as a magnetic head of readout device (1) at distance of as much as at absence of material carrier of transmitted digital data. The device for digital data transmission by inductive method (13) is capable of polarity changing of supply voltage applied to the transmitter inductance (2) with simultaneous current amplification in the transmitter inductance (2), as well as capable of hardware implementation of signal carrier polarization and software-hardware implementation of one-time-pin service.
