Data processing system for secure on-line stock transaction after query of security card and consideration of secret security number, as well as account status

摘要

An amount necessary for a transaction is released in a first stage over a data conductor (6.1) between a data entry terminal (6) and a central account computer (7) of the credit institute (8), under query of a security card and consideration of a secret security number, as well as the account status. A debit of the amount and a completion of the transaction is performed in a second stage through addition or control of data which originate from a data system associated with a registered stockbroker. The system (1, 1') includes a data entry terminal (6) connected to a central computer (7) of a credit institute (8), which is connected to a routing system (13) of the credit institute. A release arrangement (3) is provided with electronic and/or magnetic devices.
