Abstract: A banknote deposit machine is able to receive banknotes, preferably so as to make a payment, wherein the banknote machine is permanently connected via a data link to a (cloud) storage system, or is designed to establish a temporary data link with the (cloud) storage system. Banknote data, such as image data or serial number data, etc., specifically of banknotes which are considered stolen or which were handed over as a result of a crime, for example as a ransom, are stored in the (cloud) storage system. Whenever the banknote deposit machine receives a banknote whose identification appears suspicious, for example because the banknote has a serial number that is stored in the (cloud) storage system, feedback is sent to the operator of the banknote machine and/or the payment transaction is terminated and/or an appropriate institution or authority, for example the police or a security service, is automatically informed.
