  • supplying by the data carrier a transaction identification uniquely linked with the transaction data;

    generating by the data carrier a transaction acoustic signal, the transaction acoustic signal being configured to produce, upon acoustic reproduction of the transaction acoustic signal by an end device, the selected transaction data of the transaction to be cleared and the transaction identification both superimposed acoustically with a melody specific to the user of the data carrier;

    electronically transferring by the data carrier the transaction acoustic signal to the end device;

    comparing by the data carrier an electronically received transaction identification with the supplied transaction identification, the data carrier receiving the transaction identification from the end device as confirmation both of an at least partial match of the melody acoustically reproduced by the end device with the user-specific melody and of a match of the transaction data acoustically reproduced by the end device with the selected transaction data,wherein, upon the acoustic reproduction of the transaction acoustic signal by an end device with the selected transaction data of the transaction to be cleared and the transaction identification superimposed acoustically with the melody specific to the user of the data carrier, said confirmation of said matches is based on a user input to said end device of at least a portion of the transaction identification, andelectronically transferring by the data carrier a clearance signal to the end device if the received transaction identification matches the supplied transaction identification.
