Abstract
In a method for enabling the use of a consumable unit in a consumption device of a consumption arrangement, a first item of authorization information assigned to the consumable unit is transmitted from the consumption arrangement to a remote data center. The data center implements a first verification of the first item of authorization information and, as a function of this verification, a second item of authorization information assigned to the consumable unit is generated. The second item of authorization information is transmitted to the consumption arrangement, which implements a second verification of the second item of authorization information, dependent on which use of the consumable unit in the consumption device is enabled. The outcome of either the first or second verification is also used for an accounting for use of the consumable unit when, the first verification indicates that the consumable unit was previously unused.
