This chapter examines the question of whether manipulation of near-field communication (NFC) payment systems is possible, whether existing security measures adequately protect this technology, and to what extent criminality in this area has already progressed. As IT penetrates more and more areas of everyday life, this inevitably leads to new risks and dangers. This, in turn, poses new challenges to law enforcement agencies, as any specialized IT crime has to be readjusted. Initial experimental studies have already identified security risks in NFC technology. However, there are many more potential risks to check. Based on an experiment, it was examined to what extent the interception of credit cards via NFC with a standard smartphone is possible. Afterwards it was examined whether with the obtained data goods could be ordered and paid in different Internet shops. As a result, it becomes clear that reading out the credit card data by means of the NFC function of a commercially available smartphone is possible and, depending on the respective carrying situation, promises a high probability of success.
