Abstract
The method and solution can be mainly used for data transmission in cashless payment applications, especially those realized from the mobile phone while using RFID and/or NFC platform. The signals with different frequency are combined in antenna system (M) of the receiver () and transmitter () and then the carrier signal is separated from the result of the combined signals and the transmitted data are demodulated. The difference between the frequencies has a value, that corresponds to the size of the subcarrier frequency to which the receiver () is preset. During transmission the transformer connection coefficient can have the value k=0.2-0.001, while the antenna () of the receiver () is tuned narrowly to the transmitter's () frequency without considering the subcarrier frequency. The transmitter is preferably located on a memory card or on a card with a format and interface of a memory card, e.g. micro SD.
