Abstract:
A mobile communication device (4) for contactless payments has two independent chips with Secure Elements (2, 3) on its printed circuit board. One Secure Element (2) contains an indifferent POS payment terminal, the second Secure Element (3) contains a payment card. The Secure Elements (2, 3) are interconnected through a contact circuit (1 ) on the printed circuit board of the mobile communication device (4). In suitable configuration, the circuit (1) will be formed by a contact interface that will enable communication according ISO 7816. An indifferent POS payment terminal is being changed to a specific terminal in accordance with the received configuration data. The payment terminal started on the Secure Element (2) communicates over the circuit (1) with the payment card on the Secure Element (3) using the same process as if it was a payment card inserted in a payment card contact reader. The payment cryptogram can be in a standard form.
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:
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 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.
Abstract:
The antenna system has a shorter first solenoid antenna (1) and longer second solenoid antenna (2), both with magnetic core. The first solenoid antenna (1) is placed against the second solenoid antenna (2) in such a way that they are mutually parallel and the center of the first solenoid antenna (1) is on the level of the first thread (3) of the second solenoid antenna (2). The distance "a" (mm) between the transverse axes a1 and a2 of the solenoid antennas (1, 2) is a=L/2 - x where L (mm) is the length of the core of the second solenoid antenna (1, 2) and x ranges from 1 mm to 4 mm. First and/or second solenoid antenna (1, 2) can have threads formed by multiple placement of the wound circular conductor side by side or it can have threads formed by the wire bonding. The exact mutual position of the solenoid antennas (1, 2) can be chosen pursuant to the electromagnetic influence of the surrounding environment. The ratio of the first solenoid antenna's (1) length to the second solenoid antenna's (2) length ranges from 1:1,1 to 1:4, preferably from 1:2 to 1:3.

The switch (6) is timing and connects the slot (2) to voltage for the set time during which the length of the switch (6) closure can be extended by the activity followed by an additional component. The additional element will particularly be the removable memory card (4) of SD or microSD format, or the removable card (5) of SIM format and the slot (2) will have an appropriate interface. The battery can also have a Bluetooth module (7), and the Bluetooth module (7) is adapted to communicate with a host mobile communication device. The removable memory card (4) or the removable card (5) of SIM format can have an antenna to create an additional contactless communication connection, favorably of NFC type. The larger antenna (8) can be wound up directly on the body of the battery (1).
Abstract:
The method and system of authentication over a PIN code within a separate identifier (3) during a cashless payment realized over the payment terminal (1) is based on the fact that a unique identification file containing the data on a current payment is sent from the payment terminal (1) to a distance lower than 10 cm into the identifier (3) put to the payment terminal (1). The identifier (3) is supplied with energy (received and/or received and accumulated energy) in a contactless way over the payment terminal's (1) electromagnetic field. The PIN code is assigned to the received identification file in the identifier's (3) processor, the resulting file is signed electronically using the private key stored in the identifier's memory (6) and the electronically signed file thus created is sent to the payment processing centre (2) for the verification of the PIN code's correctness.

The conductive strips (2) overhang from the groundplan of the core (1) and the ends of the conductive strips (2) overhanging on both sides of the core (1) form the connecting surfaces (4). The wires (3) shaped for the encirclement of the core (1) are connected to the connecting surfaces (4), whereby the wire (3) connects a connecting surface (4) of one conductive strip (2) with the connecting surface (4) on the opposite end of the neighboring conductive strip (2). After bonding to one end of the conductive strip (2) the wire is shaped above the substrate (5) by bending in such a way that it arches over the space intended for the core (1) and all wires (3) are shaped in such a way that they produce a channel for the core (1) placed on the substrate (5). The conductive strips (2) are sloped from the normal of the core (1) under an angle pursuant to the pitch of the thread and the wires (3) are led in the opposite slope under the same angle.
