Abstract:
The process encompasses the communication between trade system accessible over GUI of the mobile communication device (4), when after the item being purchased is selected, the acquirer's (12) identification is loaded from the removable memory card (1). The acquirer's (12) identification is sent to the trade system's (2) headquarters, where after it is approved, the transaction payment parameters are created and these enter the removable memory card (1) as an initiator of the payment terminal application. The payment terminal application runs on the removable memory card (1) and it creates a payment cryptogram. This one is sent into the trade system's (2) headquarters, where it can be handled as a common cryptogram of usual POS terminals. The process can encompass even a preparation and pre-preparation phase, thanks to which corresponding applications of individual participants of the system are installed, configured and activated. The online payment can preferably realize even the reset of the counter on the payment device.
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. The production method for the antenna on the body of the removable card resides in the fact that a groove of the conductive path (5) shape is dredged on the surface of the card's body (1), the groove is filled with a conductive material and a ferromagnetic material layer (7) is applied on the surface of the area (2) covering the antenna (4).
Abstract:
Cashless payment device with prepaid credit contains a block for storage of data about the of current credit amount and is located on the removable memory card (1), which is located in the mobile communication device (4). In case of contactless top-up of electronic money on the pre-paid card, a message, preferably in the form of SMS, with the information about prepared money for the increase of the current credit is sent from the host (2) to the corresponding mobile communication device (4) according to the database of assigned numbers. The authorization request cryptogram, especially in the form of ARQC, is generated in the block on the payment device and the block is switched into the IDLE mode, in which the same authorization request cryptogram is generated permanently until the corresponding authorization response cryptogram is received, especially in the form of ARPC, which is created in the host (2).
Abstract:
A method of electronic payment transaction is characterized by the fact that during processing of one payment transaction, a communication link (3) between the card (1) and the terminal (2) is interrupted and the ARPC answering file is received to the card (1) after the original communication link (5) is interrupted. Two phases are separated by a reset of the card (1) where in the second phase initial payment data (ARQC) are used. Electronically signed ARQC payment file is stored in the card's (1) memory for at least until the corresponding time ARPC answering file is of received and processed. The solution enables to place the mobile phone with a payment card (1) near to the terminal's (2) reader twice. The first time, a request for on-line authorization is generated and during the second touch the information from the payment processor (5) is recorded into the payment application.

The secure element (4) may be configured in a memory device, which may be located in the computer mouse (1) or on a separate carrier (6). The carrier (6) may be a removable memory card, the insertion of which into a corresponding connector (7) may establish a connection between the communication element (2) and the secure element (4). The communication element (2) may include an antenna, which may be formed on a printed circuit board in the computer mouse (1). A computer mouse (1) as described herein may enable a computer (5) to communicate with a mobile communication device (3) in a secure manner.
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.
