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:
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:
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.
