Zusammenfassung:The invention relates to a method for directly transmitting electronic coin datasets between terminals, wherein a first terminal has at least one electronic coin dataset, and the at least one electronic coin dataset has a monetary value and a concealment value. The method has the steps of: determining a masking mode from at least two masking modes, a first masking mode consisting of: masking the electronic coin dataset, preferably in the first terminal, by applying a one-way function to the first coin dataset in order to obtain a completely masked electronic coin dataset; and registering a masked electronic coin dataset in a monitoring entity. The invention additionally relates to a payment system with a monitoring layer using a database, which is controlled in a decentralized manner and in which masked electronic coin datasets are stored, and a direct transaction layer, which uses at least two terminals and in which the method can be carried out.
