Abstract
For clearing transaction data selected for a processing, there is generated in a portable data carrier () a transaction acoustic signal () (S; S; S) upon whose acoustic reproduction by an end device () at least transaction data selected for the processing are reproduced superimposed acoustically with a melody specific to a user of the data carrier () (S; S; S). The generated transaction acoustic signal () is electronically transferred to an end device () (S; S), which processes the selected transaction data (S; S; S) only when the user of the data carrier () confirms vis-à-vis the end device () an at least partial match both of the acoustically reproduced melody with the user-specific melody and of the acoustically reproduced transaction data with the selected transaction data (S; S, S; S).
