Method of communication with the POS terminal, the frequency converter for the post terminal
First Claim
1. A system for contactless payment via a mobile communication device, the system comprising:
- a point-of-sale (POS) terminal having a near-field communication (NFC) antenna;
a removable memory card inserted in a respective slot of the mobile communication device, the removable memory card having an antenna; and
a frequency converter positioned between the removable memory card and the NFC antenna of the POS terminal, the antenna on the removable memory card being tuned for communication with the frequency converter,wherein the frequency converter is a flat object in a shape of a sticker and is placed in range of the POS antenna and is adapted to receive a first signal from the NFC antenna of the POS terminal, to convert the first signal to a frequency suitable for reception by the removable memory card in the mobile communication device, and to communicate the converted first signal to the removable memory card in the mobile communication device,wherein the frequency converter is further adapted to receive a second signal from the removable memory card in the mobile communication device, to convert the second signal to a frequency suitable for reception by the NFC antenna of the POS terminal, and to communicate the converted second signal to the NFC antenna of the POS terminal,wherein the frequency converter is outwardly energetically passive and is powered by an electromagnetic field on a communication path between the mobile communication device and the NFC antenna of the POS terminal, said electromagnetic field being received from the NFC antenna of the POS terminal, andwherein the flat object of the frequency converter is placed on the outside surface of the POS terminal antenna and a center of mass of a surface of the frequency converter antenna is at a distance of less than 20 mm from a center of mass of a surface of the POS terminal antenna.

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.
