Abstract
A transaction audit system is disclosed comprising a chip card, for completing a transaction between the holder of the chip card and a transaction partner such as a merchant. During the transaction, a transaction identifier is generated uniquely identifying the transaction. For completing execution of the transaction by posting of the payment amount to the merchants account, the chip card transmits a transaction receiver data record comprising the transaction identifier, and further data, if required, to a third party. To allow auditing the transaction settlement posting accuracy, the transaction provider also transmits a transaction provider data record comprising the corresponding transaction identifier to the third party. The third party is then able compare the receiver data record and the provider data record and identify possible irregularities, such as possible errors or manipulations in the transaction system, or intentional or non-intentional manipulation by the participants to the transaction, particularly the transaction receiver. The transaction identifier identifies both the transaction receiver data record and the transaction provider data record as being data records belonging to the same transaction.
