The present invention relates to a method and a system for initiating and/or conducting a transaction that is associated with at least two corresponding declarations of intent, in particular a payment transaction, between at least two transaction parties via a processing unit (3), in which payment transaction at least one of the transaction parties uses a land line telephone or mobile telephone (1, 2) or a mobile communications device for transmitting data. The method is characterized by the transmission of data to the processing unit by at least two transaction parties within a limited time frame, and by the fact that the initiation of the data transmission of these transaction parties is effected actively by the transaction parties and not by the processing unit (3), while the data transmitted during initiation contain features that enable correlating the declarations of intent with one another.

1. Method for a payment transaction between a payer and a payee using (1) two communication devices respectively associated with data transmissions by the payer and the payee and (2) a processing unit, wherein a spatial proximity exists between payer and payee, and location information of the payer is transmitted and evaluated, the method comprising: the payer's communication device transmits data to the processing unit that contain a reference to a declaration of intent that is at least directed to conducting a payment transaction associated with money or value units;using the processing unit to derive a transaction data set and an identifier of the payer from the data transmitted by the payer, and to put, using the information on the location of the payer as an additional criterion, the transaction data set into a transaction pool, wherein a plurality of transaction data sets can be present in the transaction pool within a time frame of a predefined length;using the processing unit to determine whether uniquely correlating the transaction parties on the basis of a criterion using the identifier of the payer, and using the information on the location of the payer as an additional criterion, is possible because exactly one data set, and not more, with corresponding criteria is present in the transaction pool; andif it is determined that there exists exactly one transaction data set, and not more, with corresponding criteria, said transaction data set is selected and the payment transaction is conducted according to said selected transaction data set. 2. Method for a payment transaction between a payer and a payee using (1) two communication devices respectively associated with data transmissions by the payer and the payee and (2) a processing unit, wherein a spatial proximity exists between payer and payee, and location information of the payer is transmitted and evaluated, the method comprising: the payer's communication device transmits data to the processing unit that contain a reference to a declaration of intent that is at least directed to conducting a payment transaction associated with money or value units;using the processing unit to derive a transaction data set and an identifier of the payer from the data transmitted by the payer, and to put, using the information on the location of the payer as an additional criterion, the transaction data set into a transaction pool, wherein a plurality of transaction data sets can be resent in the transaction pool within a time frame of a predefined length;using the processing unit to determine whether uniquely correlating the transaction parties on the basis of a criterion using the identifier of the payer, and using the information on the location of the payer as an additional criterion, is not possible because several data sets with corresponding criteria are present in the transaction pool; andif it is determined that there exists exactly one transaction data set, and not more, with corresponding criteria, said transaction data set is selected and the payment transaction is conducted according to said selected transaction data set. 3. A system for a payment transaction between a payer and a payee, wherein a spatial proximity exists between payer and payee, and location information of the payer is transmitted and evaluated, the system comprising: two communication devices respectively associated with data transmissions by the payer and the payee; anda processing unit for receiving data transmitted by the payer's communication device that contains a reference to a declaration of intent that is at least directed to conducting a payment transaction associated with money or value units, said processing unit being adapted to derive a transaction data set and an identifier of the payer from the data transmitted by the payer, and to put, using the information on the location of the payer as an additional criterion, the transaction data set into a transaction pool, wherein a plurality of transaction data sets can be present in the transaction pool within a time frame of a predefined length,wherein it is determined, using the processing unit, whether uniquely correlating the transaction parties on the basis of a criterion using the identifier of the payer, and using the information on the location of the payer as an additional criterion, is possible because exactly one data set, and not more, with corresponding criteria is present in the transaction pool, andif it is determined that there exists exactly one transaction data set, and not more, with corresponding criteria, said processing unit selects said transaction data set and the payment transaction is conducted according to said selected transaction data set. 4. A computer-executable program code tangibly embodied in a non-transitory computer-readable storage medium, comprising instructions for causing a processing unit to: receive data from a payer's communication device that contains a reference to a declaration of intent that is at least directed to conducting a payment transaction with a payee, said declaration of intent associated with money or value units;receive location information from the payer's communication device;derive a transaction data set and an identifier of the payer from the data transmitted by the payer, and put, using the information on the location of the payer as an additional criterion, the transaction data set into a transaction pool, wherein a plurality of transaction data sets can be present in the transaction pool within a time frame of a predefined length;enable determining whether uniquely correlating the transaction parties on the basis of a criterion using the identifier of the payer, and using the information on the location of the payer as an additional criterion, is possible because exactly one data set, and not more, with corresponding criteria is present in the transaction pool; andif it is determined that there exists exactly one transaction data set, and not more, with corresponding criteria, enable selecting said transaction data set and conducting the payment transaction according to said selected transaction data set.
