Abstract
Apparatus and method for the secured dispensing of bank papers. A signed enable message contains an overall value of the bank papers to be dispensed. A verifier checks the signature and the overall value is compared with the sum of the values of the bank papers to be dispensed. From the comparison and the incorporation of the testing of the signature, a blocking signal for the dispensing from a dispense opening is produced, as long as the signature is invalid or the overall value is smaller than the sum.
Claims30
An apparatus for dispensing bank papers comprising within a secure housing:
- a) a verifier, comprising:
- i) an input for the reception of an enable message external to the housing and containing a constraint in the form of one or more limit values as well as a signature, which signature protects the constraint against falsification;
- ii) a means for checking the signature, which, given a valid signature, provides a valid constraint for a limiter;
- and
- iii) an output in the form of a validity signal with the valid constraint
- b) a dispenser apparatus comprising:
- i) a dispenser with an input for the reception of a dispense task signal external to the housing and requesting one or more dispense tasks, which induces the dispensing of one or more bank papers;
- ii) an input for a blocking signal;
- iii) a bank paper store in which bank papers can be stored:
- and
- iv) a means that determines value features of the bank papers to be dispensed and provides these features to the limiter;
- and
- c) the limiter, the limiter being controlled independently of the dispenser and configured to emit the blocking signal as long as no valid constraint is present or the value features do not fulfill the constraint,
- wherein
- the apparatus for dispensing bank papers is configured such that the blocking signal prevents final dispersion of bank papers failing to meet the constraint.

A method for the operation of an apparatus for dispensing bank papers enclosing a dispenser, a verifier and a limiter, said method comprising the steps of:
- transmitting an enable message from a source external to the apparatus to the verifier, which enable message contains a constraint in the form of one or more limit values, as well as a signature, which secures the constraint against falsification;
- checking the signature with the verifier to see whether a valid constraint is present, and transmitting this constraint to a limiter;
- transmitting one or more dispense tasks to a dispenser, from a source external to the apparatus, the dispenser thereupon dispensing of one or more bank papers, and, for each bank paper to be dispensed, determines one or more value features and transmitting these value features to the limiter;
- producing a blocking signal with the limiter as long as no valid constraint was transmitted by the verifier or the value features transmitted by the payment unit do not correspond to the constraint;
- preventing dispensing the bank papers determined by the dispense tasks.
