摘要
The method involves establishing a first communications link between an authorized user and a data center, storing a code for a message announcing an authorized transaction for a subsequently transmitted pre-set request; switching on the franking machine to perform a predefined process to enter a special mode for a negative remote value pre-set; establishing a second communications connection between the franking machine and the data center and entering a pre-set request. A first transaction is performed after the machine enters communications mode to set a pre-set request according to a residual credit value to be transferred if the command process corresponding to a permitted process, as opposed to an unauthorized operation. The method further involves transferring and storing the security-relevant data or clearing a security flag for an impermissible deviation from the command process and disabling the franking machine. An Independent claim is also included for an arrangement for implementing the method.
