ABSTRACT:
A method which allows the continued use of a credit card which is expired in terms of time or value units for automatic vendors which are in communication with a central evaluation location. The method of the invention allows a continuation of telephone calls, for example, even with an expired telephone credit card. This occurs in that debiting of the fee units used or made to the account of the card owner at the central evaluation location in a chronologically limited transition time after every service performance so that a call is not cut-off in the middle of a call.
