DESCRIPTION:

BRIEF SUMMARY
This invention relates to a method or producing a controlled number of authorization members such as authorization cards, identity cards, check or value cards, etc., more particularly cards used for limited access to automatic service machines, automatic bank counters, administrations, restricted areas, etc.
A primary safety condition for any system allowing only authorized persons to perform specific operations by using an authorization card is that the production of the actual authorization cards should be possible only for authorized persons. Thus, the activation and the delivery of authorization cards should be restricted to a specific procedure to be defined in advance. Of course, security measures are necessary to avoid an unauthorized activation and delivery.


OBJECTS OF THE INVENTION

It is a primary object of the invention to provide a unique method of producing a controlled number of authorization members preventing an unauthorized activation and delivery of such authorization members, particularly of authorization cards.
It is a related object of the invention to provide a method of producing a controlled number of authorization members allowing the generation of a record with respect to any authorization members produced, particularly the number and scope thereof.
It is a still further object of the invention to provide a sequential method of producing authorization members by successive enabling of activating stations using an hierarchical system of unique authorization members each associated with a limited scope of authorization to produce a determined lot of authorization cards.


SUMMARY OF THE INVENTION

In accordance with the invention, authorization members are produced from blank data carriers such as cards of paper, paperboard, plastics, etc., having a storage medium such as a magnetic strip, and requiring no security measures prior to their activation in an activating station by storing coded data on the storage medium. To produce a limited number of authorization cards, a hierarchical system of unique production authorization cards is used each associated with a predetermined scope of authorization with respect to the number and type of authorization cards to be produced. In a preferred embodiment, the hierarchical system comprises an original card associated with the manager of the system and used to enable a first activating station; a charging card produced by activating a blank data carrier card in the first activating station; a master card produced from a blank data carrier card in a second activating station using the charging card to enable the second activating station; an instruction card produced from a blank data carrier card in a third activating station using the master card to enable the third activating system; and the actual authorization cards produced from blank data carrier cards by enabling a fourth activating station by introduction of the instruction card. While the charging card is associated with a predetermined total number of authorization cards allowed to be produced, the master card is associated with a predetermined fraction of the total number, i.e. a partial lot thereof, and the instruction card is associated with only a fraction of the partial lot, i.e. a sub-lot of the total number.


DESCRIPTION OF A PREFERRED EMBODIMENT

Further features and advantages of the invention stand out from the description of an exemplary embodiment with reference to the FIGURE. This FIGURE shows a schematic representation of the production of authorization cards.
The authorization members 1, termed authorization cards in the following description, are for example produced from blank data carrier cards 7 of paper, cardboard or plastics, provided with a magnetic strip. They bear no secret code and are worthless so that no security measures are necessary. The activation of these blank cards 7 comprises a sensing detection of the specific individual physical properties of a specific data carrier card that cannot be reproduced. From the detected properties, an authenticity
