Abstract:
NFC antenna system has at least one pair of solenoid windings (1) which are placed in a single plane and have a common axis (3). The solenoid windings (1) are connected to the excitation and are oriented in such a way that their magnetic fields are mutually opposite. The distance between the middles of the solenoid windings (1) is at least twice their length; usually the distance is 35 to 45 mm when the length of the solenoid windings (1) ranges from 5 to 20 mm. In a preferable arrangement each solenoid winding (1) has its own, independently controlled excitation element (4), whereby the excitation elements have a modulation input connected and they have a same excitation frequency. The end levels of the excitation element (4) are independently controlled by means of the control inputs to switch the end levels on and off, which allows for simple alteration of the modulation depth. In one pair of the solenoid windings (1) the change can be set in a range from 25% to 100% with a 25% step. The significant advantage of the invention is the diminishing of the surface needed for placement of the NFC antenna on the carrier, mainly on the PCB of the mobile phone.
Abstract:
The emitter is intended to provide a contactless communication channel (particularly RFID/NFC) in miniature build space. The emitter has an oblong, at least partially ferrite core (1), the core (1) is winded up by a wire (4) with at least two threads (2), the threads (2) are on the core (1) placed tightly next to each other and the effective width (w)of one thread (2) corresponds to the radius of the core (1) in the circular core (1) cross-section, or corresponds to the equivalent radius in other shapes of the core (1) with deviation up to +−75%. The wire (4) of the coil is flat, or the coil includes several wires held parallel to each other (41 to 4N) forming a multi-stage thread. The emitter can be placed in the removable memory card (5) and/or on the PCB board (10) and/or SIM card (9) and/or battery (11). Modulation of data transmitted by the emitter uses electromagnetic wave generator with a frequency different from the receiver, difference of these frequencies corresponds to the subcarrier frequency.
Abstract:
A temporary carrier of a removable memory card (2) is in the shape of a flat card (1), where the removable memory card (2) forms an element to be released from the flat card body (1). The removable memory card (2) has at least five additional contacts (4) for temporary usage before the removable memory card is removed from the flat card (1) body. The additional contacts (4) take up a smaller surface as a contact field (5) of a standardized flat card (1). The removable memory card (2) is located within the flat card (1) in such a way that the position of additional contacts (4) corresponds to the position of a standardized flat card (1) contact field (5). The suitable sixth additional switch contact (8) can be used to switch secure elements. The temporary carrier is inserted into a standard burning device, which operates with it in the same way as it would with a common card with a contact field (5).
Abstract:
An indifferent payment-terminal application is located in the payer's (6) mobile phone (4). As a response to payer's (6) request, the mobile phone (4) requests the payment terminal configuration data belonging to a desired money recipient (7) from the center (1 ); subsequently, from the indifferent payment terminal, a specific POS (8) payment terminal of the payment recipient's (7) bank (2) is created using the received configuration data. The POS (8) created in this way communicates with the payment card located within the payer's (6) mobile phone circuits and subsequently the payment cryptogram is sent by the payer's (6) mobile phone (4) to the center (1 ) to be processed in the payment recipient's (7) bank (2). POS (8) terminal creates a cryptogram in the form of TC or ARQC or AAC within the payment-terminal application and besides sending it into the center (1 ) it stores it into the memory in the mobile phone (4), which stops the course of the payment-terminal application until a response in the form of ARPC arrives.
Abstract:
The payment card, apart from a chip with the common payment card unit, also contains a second chip with an indifferent POS payment terminal, which becomes a specific POS terminal on behalf of the payments recipient after connection with the reader of the payments recipient. These two chips on the payment card are connected in a contact way. The reader contains the common POS terminals identification data which are sent 10 to the payment card of the customer, where they are moved to the second chip for the configuration of the POS terminal. Then on the payment card, the payment-terminal application is realized as if it were a common POS with the inserted card in a contact way, using the payment account data from the first chip. The payment cryptogram generated in the other chip on the payment card is sent to the reader for payment processing on 15 behalf of the reader-holder (merchant).
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:
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:
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.
