A method for data-related allocation of an non-person-related NFC-enabled terminal and an NFC chip card suited for data-related connection to said terminal, to a transaction wherein a data access is made to the NFC chip card and a second chip card, wherein the type of the transaction to be performed is selected by a first instance, namely a first person, wherein the method comprises the following steps: a) transmission of transaction data which are relevant for the transaction, via a wireless or wired data link, from a further instance to a transaction control system (18, 18a), b) generating a reference code allocated to the transaction, particularly under cooperation of the transaction control system (18, 18a), wherein the reference code on the transaction control system (18, 18a) is allocated to the second chip card, and wherein the reference code is transmitted from the transaction control system (18, 18a) or from another component that has generated the reference code to the further instance and by this further instance is passed on to the first person, whereupon the reference code is passed by the first person to the terminal, c) transmission of the reference code from the terminal via a wireless or wired data link to the transaction control system (18, 18a), and allocating the terminal being with the first person at the time of performing the transaction to the second chip card and to the to-be-performed transaction, wherein this assignment is performed by the reference code transmitted from the terminal to the transaction control system (18, 18a), d) transmission of the transaction data from the transaction control system (18, 18a) to the terminal via a wireless or wired data link, wherein the transaction data exclusively of that transaction are transmitted which was allocated to the terminal within the method step c) by the reference code transmitted from the terminal, e) applying the NFC chip card to the terminal whereby the transaction is started, f) performing the transaction, wherein, via the terminal to which the NFC chip card was applied and which was allocated to the second chip card via the reference code, data-related access is made to the NFC chip card and wherein, via the transaction control system (18, 18a), data-related access is made to the second chip card. a) transmission of transaction data which are relevant for the transaction, via a wireless or wired data link, from a further instance to a transaction control system (18, 18a), b) generating a reference code allocated to the transaction, particularly under cooperation of the transaction control system (18, 18a), wherein the reference code on the transaction control system (18, 18a) is allocated to the second chip card, and wherein the reference code is transmitted from the transaction control system (18, 18a) or from another component that has generated the reference code to the further instance and by this further instance is passed on to the first person, whereupon the reference code is passed by the first person to the terminal, c) transmission of the reference code from the terminal via a wireless or wired data link to the transaction control system (18, 18a), and allocating the terminal being with the first person at the time of performing the transaction to the second chip card and to the to-be-performed transaction, wherein this assignment is performed by the reference code transmitted from the terminal to the transaction control system (18, 18a), d) transmission of the transaction data from the transaction control system (18, 18a) to the terminal via a wireless or wired data link, wherein the transaction data exclusively of that transaction are transmitted which was allocated to the terminal within the method step c) by the reference code transmitted from the terminal, e) applying the NFC chip card to the terminal whereby the transaction is started, f) performing the transaction, wherein, via the terminal to which the NFC chip card was applied and which was allocated to the second chip card via the reference code, data-related access is made to the NFC chip card and wherein, via the transaction control system (18, 18a), data-related access is made to the second chip card.
