Abstract: A payment terminal using a mobile communication device, such as a mobile phone, is located on a removable memory card (1) which is adjusted in such a way so it can be inserted into an additional hardware slot which is used to add functionalities that surpasses the basic functions of the mobile communication device. (4). A payment POS terminal application runs on a removable memory card (1), which also contains at least one payment card. The configuration data of the terminal's selected identity and the payment card's data are located in the separate parts of the secure element (3, 31, 32) or in completely independent secure elements (3, 31, 32). The payment card's unit (7) with the card's payment application is located in the secured part of the memory, separately from the terminal's configuration data unit (6). The memory card (1) is of SD type or miniSD or microSD card or an M2 card.

Abstract: When processing repeated operations on the keyboard of a mobile communication device, mainly at direct debits, used is a separate data carrier with a memory in which is stored at least one file with a sequence of keyboard orders of a macro type. Data carrier is energetically supplied contact-free by electromagnetic field of the mobile communication device while receiving the requiring order and, according to this order, chooses from the memory and encodes appropriate file with a sequence of keyboard orders. Data carrier sends the encoded file into the mobile communication device which decodes the received file and performs processes representing the keystrokes according to the sequence of keyboard orders. The invention also describes connection and data carrier to perform above described method where the data carrier consists of a processor, transmitting and receiving unit, block for transforming electromagnetic field and a memory to store a file of orders.

Abstract: The system contains a virtual POS terminal's unit in the user's personal device. The mobile communication device (1) contains a virtual POS terminal's unit (4) and also a removable memory card (3), on which there are at least two physically separate secure elements (2) stored. The removable memory card (3) is connected to the secure element (2) containing the secured part of the virtual POS terminal. The mobile communication device (1) and/or the separate portable element (6) is adjusted in such a way to be able to connect to a remote payment procession server. The removable memory card (3) and the separate portable element (6) can be equipped with the NFC communication element. Depending on the user choice, a corresponding secure element (2) with the selected payment card unit (14) is activated on the removable memory card (3).

Abstract: The system consists of a POS terminal (6), a secure element (2), a mobile communication device (1) with a display and a keyboard, such as a mobile phone. The mobile communication device (1) is equipped with a removable memory card (3), in which there are at least two physically separate secure elements (2) located. The mobile communication device (1) is connected to the POS terminal (6) through a contactless transmission channel (5) and at least one secure element (2) on the removable memory card (3) contains a payment card unit (9). The removable memory card (3) contains a NFC communication element (7). The system can also encompass a separate carrier (13) for PIN entering. The carrier (13) is energetically supplied from the field of the received electromagnetic field. During the payment's authorization, the managing unit (4) in the mobile communication device (1) activates a corresponding secure element (2) with the chosen payment card unit (9) on the removable memory card (3).

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.

Abstract: Removable card for a contactless communication contains an antenna (4) formed of threads (10) placed on the external surface of the body (1) of the card and covered by a layer (7) of a ferromagnetic material. In advantageous adjustment the antenna (4) contains on one area (2) of the card eight threads (10) and both areas (2) of the card are covered by a layer (7) of a ferritic foil. The antenna (4) is connected to the series with element (12) with capacity and the resistance (11) on the other side. Resonant circuit is tuned in for the final frequency from 13.0 to 15.0 MHz. The signal from the antenna (4) is read between the first and the second thread (10) from the side of the element (12) with capacity.

Abstract: The method and system of authentication of authorized person and transaction approval principally at the direct debits by means of a mobile communication device (2) is based on the fact that an alphanumerical chain is sent from the mobile communication device (2) into energy passive identifier (3) approached to the mobile communication device (2), the identifier (3) is supplied contact free by electromagnetic field of the mobile communication device (2) while in the identifier the received alphanumerical chain is signed electronically and in such signed alphanumerical chain is sent back into the mobile communication device (2). Payment approval is realized by the correctness approval of the electronically signed alphanumerical chain and by approaching the mobile communication device (2) to the payment terminal (1). The invention enables to use a high level of cryptography security by using a passive identifier (3) which does not demand own energy source.
