A system for evaluating currency bills with currency evaluation machines and recording information associated with the evaluated currency bills. The currency evaluation machines utilize sensors to obtain information from the evaluated bills, and comparison tests are performed in which the sensor information is compared to master information in order to identify the denomination, series and authenticity of the currency bills being evaluated. A reviewable record of the comparison tests is maintained for each individual currency evaluation machine. After performing the comparison tests, evaluated bills are identified as either no call bills, suspect documents or genuine bills. Information associated with respective no call bills, suspect documents or genuine bills, including times of occurrence or quantities of no call bills, suspect documents or genuine bills, and/or denomination of suspect documents or genuine bills is recorded in the reviewable record. In one embodiment, the reviewable record is communicated from a network of individual currency evaluation machines to centralized controllers which maintain an aggregate record of information compiled from the individual machines. |

DETAILED DESCRIPTION In accordance with one aspect of the present invention, there is provided a currency discriminator for evaluating currency bills and recording information associated with the evaluated bills.
The currency bills to be evaluated are generally unidentified and unauthenticated.
The currency bills to be evaluated are transported, one at a time, from an input receptacle to an output receptacle along a transport path.
First and second scanheads positioned along the transport path obtain respective first and second types of detected characteristic information from the currency bills being evaluated.
A system memory stores first and second types of master characteristic information corresponding to genuine currency bills of assorted denominations and/or series.
A microprocessor performs respective first and second comparison tests to identify and determine the authenticity of the currency bills being evaluated, and recording means is provided for maintaining a reviewable record of the first and second comparison tests.
In the first comparison test, for each individual bill under test, the microprocessor evaluates whether the first tape of detected characteristic information obtained from the bill under test sufficiently matches an item of the first type of master characteristic information corresponding to a particular denomination and/or series of bill.
If a positive determination is reached in the first comparison test, the microprocessor identifies the denomination and/or series of the bill under test.
If a negative determination is reached in the first comparison test, the microprocessor generates a no call error signal indicating that it is unable to identify the denomination and/or series of the bill under test.
The transport mechanism may be halted upon each occurrence of a no call error signal to permit removal of the no call bill or document.
Information associated with the no call error signal(s) including, for example, times of occurrence or quantities of no call error signal(s) is recorded in system memory for subsequent review
