摘要

The system has an identification device, and a point-of-sale system (B) physically connected with a central archiving system (A). A system input (G) is connected with the archiving system. A signature and cryptographic device is connected with the point-of-sale system, where identification of consumers is carried out during each transaction. The signature and cryptographic device is provided for signing and cryptographically securing receipt and bill data. The data is transmitted (3) to the archiving system, where access to the data is carried out over the system input.
