Computer-aided database information and commercial cashless transaction system - has security technology and electronic access control and payment guarantee, and exchanges information and funds between customer accounts and supplier account via decentralised computer

摘要

The system uses a decentralised, remote computer and a central host computer. The authorised computer (5.1) has access to a regional database (1) which, at the same time, represents the central system. The software serial number (15), the access counter (16) and the hardware serial number (17) are processed via the hardware encoder (14) to a character train. This is sent via the interface (13) to the host (1). The train is processed and blocks or allows access to the system. By means of the database (1), the second account of the customer can be increased from their first account. The necessary payment is made to the supplier account via the data bank and the second account. A constant decentralised data record is located at regional data management locations and/or the regional database and data is exchanged via national databases and further databases.
