- Such applications include also so-called “point-of-sale applications”, ie applications in which the device essentially fulfills the functions of an electronic means of payment, or also security applications in which the device serves as a means of identification or authentication.
- point-of-sale applications * are probably only special cases - albeit with further refinements - of the security applications, since in an electronic payment process at least the payee, but usually also the paying participant, has the need, identity and authorization of the other participant.
- PDA Personal Digital Assistants
- telecommunications module a small device with or without a telecommunications module
- Such interfaces have basically been known for a long time. Examples are infrared interfaces or short-range radio interfaces, e.g. according to the "Bluetooth * standard.
- Short-range contactless (“wireless *) data transmission interfaces are particularly suitable for local communication.
- wireless * Short-range contactless
- they have the advantage that the group of possible communication partners is focused on the closer, often immediately manageable, environment from the outset. is limited.
- temporary connections are already being established between PDAs for the transmission of “electronic business cards * or other data by bringing these PDAs into close proximity and / or aligning their infrared interfaces with one another. So you can be reasonably certain - and sufficient for many applications - that the desired communication partner is actually the one with whom communication is taking place.
- FIG. 2 shows in a schematic way the treatment of the special case that from the start there is only a second radio station in the vicinity of the first radio station.
- the present invention is based on the basic idea that, in very many applications, the intended communication partner differs from all other possible and unintended communication partners (“third parties”), for example, by its position or other properties that can be easily influenced by the user, that the transmission properties of the contactless interface (e.g. the radio channel) between it and a first radio station (FSl) looking for the connection establishment meet a certain quality criterion that is not met by all other possible communication partners, or that such a difference in the transmission properties is at least due to changes at least one operating parameter of the first radio station (FSl) can be brought about.
- third parties for example, by its position or other properties that can be easily influenced by the user, that the transmission properties of the contactless interface (e.g. the radio channel) between it and a first radio station (FSl) looking for the connection establishment meet a certain quality criterion that is
- FIG. 1 A simple and typical example of such a situation is shown in FIG. 1.
- Several second radio stations (FS2a, ..., FS2d) are located in the vicinity of the first radio station (FS1), which is to establish a connection with a second radio station.
- the first radio station could be a checkout system in a department store.
- second radio stations (FS2a, ..., FS2d)
- cell phones or other small devices come into consideration, all of which are in principle able to connect to the first radio station (FS1).
- These second radio stations are usually owned by different people, who are usually (potential) customers of the department store.
- radio station FS1 cannot initially “know” from any customer how it should be able to recognize its radio station FS2b. Therefore it would be relatively easy for leather "third parties *" to operate their radio station in such a way that the POS system can process the payment - e.g. also be a refund for an exchange - processed with his radio station.
- the radio station FS2b is, however, as shown schematically in FIG. 1, distinguished from all other radio stations in that it has the smallest distance from the cash register system (FS1). Consequently, it should be possible to change the transmission power or the reception sensitivity of the radio station FS1 in such a way that a communication connection or communication relationship is only possible with this one radio station FS2b.
- the first radio station (FSl) was able to send out a first call signal or connection request signal (crl), the range of which is so large due to an initially relatively high transmission power that initially all four second radio stations shown in FIG. 1 can still receive this signal. Consequently, in this step, all four second radio stations transmit one response signal (r2a, ..., r2d), so that all four response signals can be received by the first radio station FS1 if the reception sensitivity is sufficiently high.
- the transmission power of the first radio station FS1 can now be reduced on a trial basis. Or it could reception sensitivity would be reduced. It would also be possible to reduce both sizes at the same time.
- At least after one such step at least one of the four second radio stations will no longer respond or its response will no longer be received by the first radio station. So e.g. If the transmission power is reduced to such an extent that the connection request signal cr2 no longer reaches the second radio station FS2c, the latter does not respond. The other three second radio stations (FS2a, FS2b and FS2d) still answer because they could receive the signal cr2. In a next step, the transmission power of the first radio station FS1 could be further reduced, e.g. only FS2b answers or the reception sensitivity could be reduced to such an extent that only the response from FS2b can be received.
- the transmission power could also be reduced further, so that a third connection request signal cr3 no longer reaches the second radio stations FS2a, FS2c and FS2d, but still reaches the second radio station FS2b.
- a third connection request signal cr3 no longer reaches the second radio stations FS2a, FS2c and FS2d, but still reaches the second radio station FS2b.
- only the second radio station FS2b would send out a response r2b that can be received by the first radio station FS1.
- the use can be used, for example, to establish a communication connection between a cash register system (ST) with a radio module and a customer device (CD) with a radio module (WM), in particular with a mobile phone (MP).
- ST cash register system
- CD customer device
- WM radio module
- MP mobile phone
- the devices involved do not have any addresses or identifications. tifiers of the other device must be known. With such addresses or identifiers, it would of course also be possible to ensure that (only) the "right" devices participate in the payment process. For example, the user of the checkout system could manually enter a device identifier of the customer device involved in the payment process into the checkout system, which is unknown to other people present. That would be quite cumbersome for the considered applications. It is therefore an advantage of the method according to the invention that this complicated and possibly error-prone procedure can be omitted.
- the cash register system or, more generally, a service terminal can transmit such a device address or device identification directly to the actual customer device involved, as soon as the communication relationship between the two is purely bilateral, by radio.
- a device address which may be temporary, i.e. only valid for the current payment process
- communication can now be secured against unintentional interference or attacks by third parties, even if the criterion of the smallest spatial distance is no longer met after this security has been set up should. It is not necessary to enter an address from outside - in other words via the radio path - in the method according to the invention.
- the customer actually involved in the payment process only has to bring his mobile phone or other customer device near the cash register once and can then keep it at a greater distance from the cash register again - even while the payment process is still ongoing.
- This property of the invention significantly increases the comfort of the people involved in the handling of the payment process.
- Another advantageous application of the invention is in connection with the registration of subscriber stations (SM) at base stations (BS) of cellular or other wireless communication systems.
- communication systems especially cordless telephone systems according to the DECT standard possible.
- the base station only has to e.g. reduce its transmission power until only communication with the subscriber device to be registered is possible.
- This method also has the advantage that mutual identification of the devices can take place directly via the air interface (ie via the radio channel) without external transmission of such identification information.
