Abstract
The communication method with the POS terminal that improves transmission characteristics of the authorized payment from the mobile communication device (9) is based upon a fact that the frequency converter (1) on that side of the communication channel where the POS terminals NFC antenna (8) is. The frequency converter (1) receives and processes the signal from the POS terminals NFC antenna (8) on the 13.56 MHz frequency, sends it on a higher frequency into the mobile communication device (9) and vice versa. The frequency converter (1) is outwardly energetically passive and is power supplied from the electromagnetic field received from the POS terminals antenna (8). The frequency converter (1) contains an antenna, tuned to the frequency in the range of 13.00 to 14.00 MHz, that is connected to the power supply element (4). The frequency converter (1) is located in the proximity of the POS terminal'"'"'s antenna.
