1. A method of processing currency bills in a document processing system, the method comprising: receiving currency bills in an input receptacle of the document processing system, each of the currency bills being associated with a denomination, a serial number, and a set of secondary identifiers; transporting the currency bills from the input receptacle in a serial fashion, past an image scanner, to one or more output receptacles; imaging each of the currency bills via the image scanner to produce image data from which a visually readable image of each currency bill can be reproduced; determining that one of the currency bills is a suspect bill; attempting to determine the denomination of the suspect bill; attempting to extract the serial number from the image data associated with the suspect bill; attempting to extract the set of secondary identifiers from the image data associated with the suspect bill; and in response to determining that a currency bill is a suspect bill, generating a suspect report, the suspect report including a denomination field, a serial number field, and a plurality of secondary identifier fields, the act of generating the report comprising: (i) populating the denomination field in the suspect report with a denomination snippet image; (ii) populating the serial number field in the suspect report with a serial number snippet image; (iii) populating each of the plurality of secondary identifier fields in the suspect report with a corresponding secondary identifier snippet image; (iv) in response to determining the denomination of the suspect bill, further populating the denomination field in the suspect report with the determined denomination; (v) in response to extracting the serial number of the suspect bill, further populating the serial number field in the suspect report with the extracted serial number; and (vi) in response to extracting one or more of the secondary identifiers of the suspect bill, populating corresponding ones of the plurality of secondary identifier fields in the suspect report with corresponding ones of the extracted one or more secondary identifiers.
