Description

 Means for unidirectional or bidirectional data transmission

 The invention relates to a system for the transmission of data between a

Touchscreen having device and a send and / or

Receiving device. Furthermore, the invention relates to the use of the system and a method for data transmission.

 In the digital age, the smartphone or other portable electronic device becomes a constant companion, with more and more tasks being added to the original ones. An essential task of the devices is the management of data, such as contact data, access data, notes, but also financial data that allow, for example, the mobile management of the bank account. Also the

Use of the device to purchase goods or services is possible.

 Thus, it is necessary to provide for these digital companions a device which enables communication with the devices and achieves a secure, fast and complex data exchange with the electrical device. Data exchange is a term used in electronic data processing and refers in particular to the transfer of data between electrical devices, such as computers, system components or programs.

 The state of the art describes the so-called "Near Field Communication" (NFC), which is a standardized standard for the transmission of data in the near range, that is to say over a short distance of a few centimeters, whereby the transmission does not take place with cables, but wirelessly.

 Data transfers via NFC are mostly intuitive, that is, an NFC enabled device such as an NFC phone, just gets close to another NFC device or one

Disk (for example, a so-called NFC tag) held on the information. Thereupon the data transmission and possibly the associated application starts automatically and / or after a short confirmation by pressing a key.

 In this case, a maximum transmission speed of 424 kBit / s can be achieved. The data transmission takes place by means of NFC and thus slower than with related ones

Techniques such as Bluetooth or WLAN, but it also provides crucial benefits in terms of security. This makes NFC the basis for cashless payment systems or

Access controls.

The transmission of the data can be both uni- and bidirectional, connected devices can thus exchange data in both directions and thus lead a dialogue. For example, NFC technology allows you to perform various types of transactions, exchange digital content, or connect electronic devices. Basically, there are three different modes for NFC data transmission:

 • Reading information stored on a passive memory by

 NFC device. For example, Broadcast a concert date from an NFC tag attached to a poster for storage and reminder on an NFC phone.

 · Reading information from an NFC terminal through an active NFC

Medium. For example, the reading of the stored on an NFC mobile electronic concert tickets through an NFC terminal in the entrance area.

 • Bidirectional exchange of data between two NFC devices in dialog.

 Furthermore, various methods for protecting against manipulation of transactions are known from the prior art. In the electronic execution of banking transactions, the use of the PIN / TAN method in various forms is used in particular. In this case, a user logs in via a PIN using his browser on the bank server of his bank and transmits over a corresponding data connection, which is preferably cryptographically secured, the transaction data of the transaction to be performed.

 The document WO 2008/046575 A1 describes a method for carrying out an application with the aid of a portable data carrier, in which the application is carried out with the aid of a first and second terminal with the interposition of the data carrier. The method can also be used in particular for the execution of electronic

Bank transactions are used. The communication that takes place always takes place with the interposition of the portable data carrier. In the method, transaction data is first input via the first terminal, wherein the first terminal is in particular a personal computer. Thereafter, the data is transmitted to the portable data carrier to a second terminal, for. B. to a mobile phone, forwards. The transaction then has to be released by a user by means of an input at the second terminal, whereupon the transaction data from the

Data carriers are transferred to a server that executes the transaction. The document US 2003/0087601 A1 describes the use of a security token with two interfaces for secure data transmission between a mobile telephone and a PC. The token communicates via a contactless interface,

for example, based on Bluetooth or infrared, with the mobile phone and via a contact-bound interface with the PC.

Furthermore, it is disclosed in the prior art that portable data carriers can be equipped with a chip and data or individual personal data can be stored thereon. However, the writing of the data is only a suitable one Data communication connection from an out-of-disk writer to the embedded chip possible. In this context, it is known to provide contact areas on the outside of portable data carriers via which data carrier or person-specific data (eg personalization data) can be written into the chip of the data carrier. Such data carrier individual or personalized data relate to individualizing data of a person or a person

Volume configuration or the like, which can not be played during the initialization of the disk, since they are in particular no suitable for a variety of media data carrier and / or person-independent data. For this purpose, the data carrier or person-specific data via a contact field of

 Disk written in the fully embedded in a plastic substrate chip.

Such contact fields are visually striking and create over the entire life of the data carrier a basic access to the sensitive data in the chip, which could be exploited for manipulation and spying. In addition, they reduce the life of the chip, since external influences such. As electrostatic voltages or discharges can enter directly into the chip or even destroy it. Likewise, the difficulty arises that such electronically personalized, d. H. subsequently provided with personalization data storage medium not readily optical visualization - d. H. a visible, individualizing label or embossing - can be assigned as the inscribed in the chip

 Personalization data in the optical personalization can be difficult to read.

 For example, DE 195 00 925 A1 discloses a chip card for contactless

Data transmission, however, which is provided on one of its outer sides with contact surfaces, so that the above-mentioned disadvantages in connection with the personalization also occur here.

 Numerous electronic devices are described in the prior art, which have a touch-sensitive screen (touch screen), which is also referred to as a touch screen and can be operated with fingers or input devices.

Touchscreens are in almost every area of life these days. Their intuitive operation makes it easier for inexperienced users to easily operate technical devices in the everyday world and can be used to operate an electronic device. In other words, they are used both in everyday life and in industry, in which touchscreens are used, for example, to control machines or in the field of the games industry, where they are used for gaming machines or arcade games. Other examples of touch screens include smartphones, Cell phones, displays, tablet PCs, tablet notebooks, touchpad devices, graphics tablets, televisions, PDAs, MP3 players, and / or other input devices.

 A touch screen can also be part of input devices. Such input devices are used, among others, in smartphones, PDAs, touch displays or

Notebooks used.

 Generally one understands under a touch screen, also touch screen or

Called a touch screen, a touch-sensitive layer placed on the screen that responds to contact of the user with his or her finger or a stylus suitable for the technology used. The touch screen is an input device with direct effect, that is, the input is made directly on the displayed space, not off the screen, as would be the case with a mouse or keyboard. In addition, the positioning on the touchscreen is absolute, ie it is not dependent on the previous position. Consequently, touchscreens offer a very intuitive operation, since the screen also serves as a user interface and does not need to be chosen via external input devices.

 The touchscreens are based on different principles of operation, with resistive and capacitive technologies being the most common. Resistive touchscreens, for example, consist of two opposing, transparent, conductive ITO layers (indium tin oxide), which are separated by numerous isolated spacers, so-called "spacer dots." For example, the inner ITO layer is on a solid glass screen; Layer is protected by a flexible, scratch-resistant plastic film.

 By means of a control device, a voltage is alternately applied to the conductive layers, so that e.g. a voltage gradient in the X direction is generated on the inner layer, and e.g. on the outer layer, a voltage gradient in the Y direction. As soon as the screen is touched, the upper layer is pressed onto the underlying one, thus making electrical contact and forming a voltage divider, the size of which results from the position of the contact point on the live layer, through the respective de-energized layer on the live layer. From this, the corresponding X and Y coordinates of the touch point can be calculated.

In contrast, in capacitive technology, for example, two spatially separate planes, such as the top and bottom of a foil or a glass substrate, respectively a plurality of mutually parallel conductor tracks made of conductive material applied. Capacities are formed at the crossing points of the horizontally extending interconnects of one level and the vertically extending interconnects of the other level. The electrical control of the tracks of a plane (transmission lines) generates a measurable signal on the tracks of the second level (receiving lines). By touching the system by a user eg via his finger, the capacitive coupling between the transmitting and receiving lines is affected, so that the signal of the receiving line is changed. Subsequently, the resulting signal changes are evaluated and determined on the basis of the respective transmit and receive lines, the coordinates of the touch. In addition to a single touch, multi-touch recognitions are also possible, so that multiple fingers or input elements can trigger a touch event.

Furthermore, touch screens are known that use an infrared technology, acoustic

Use surface wave technology or dispersive signal technology.

 Accordingly, it is the object of the invention to provide a means which does not have the disadvantages or deficiencies of the prior art and a safe

Data transfer with a mobile device allows.

 The object of the invention is solved by the independent claims. Preferred embodiments will be apparent from the dependent claims.

Substrate layer designated. It may be preferred that the transmit and / or

 Receiving device is activated, for example, by the device having the touch screen and only after activation data transmission takes place. The activation can be effected for example by means of optical, acoustic, electrical, haptic or tactile signals or means.

For the purposes of the invention, bringing into contact means that in particular the transmitting and / or receiving device is in functional interaction with the touch screen and preferably there is no free space. That is, the disk is preferably in touch contact with the touch screen. However, it may also be preferred that there is no direct contact between the plate and the touch screen, but there is only one approach sufficient to make one

 On the plate of the transmitting and / or receiving device, which can be referred to as an electrode plate in the context of the invention, at least one electrically conductive surface is applied. The shape of the surface is arbitrary and can be designed in different designs. For example, round, square or oval surfaces or

Generate, delete and / or modify touch points. Extinguishing in the sense of the invention means in particular that the conditions for displaying a touch point are no longer met, e.g. by falling below a threshold value. These touch events surprisingly make the interactions for the

For example, the energy could be provided from the touch screen that is in contact with the device. The device can also advantageously be supplied with electrical energy by means of induction (eg an induction coil).

For example, each electrically conductive surface has a derivation in the form of conductor tracks or conductor tracks to the control unit.
