Abstract

A device for directly transmitting electronic coin data records to another device includes accessing data storage, such that an electronic coin data record is stored in the data storage; an interface at least for outputting the at least one electronic coin data record to the other device; and a computing unit configured to mask the electronic coin data record in the device by applying a homomorphic encryption function to the electronic coin data record to obtain a masked electronic coin data record for registering the masked electronic coin data record at a monitoring entity; and to output the electronic coin data record using the interface. A payment system has a monitoring layer including a database in which masked electronic coin data records are stored; and a direct transaction layer including at least two devices in which the method can be carried out.
