Abstract

A document handling system is adapted to evaluate documents such as currencies of any denomination or type without having been pre-programmed with data representative of the denominations or types. The currency handling system is capable of generating such data internally, by scanning sets of master currency bills to obtain master information representative of the master bills which may be used to evaluate subsequent test bills. The master currency bills may comprise bills of different currency types, including bills issued by different countries. The master information may comprise numerical and/or non-numerical data. The evaluation of the test bills is based on a comparison of either pre-stored or self-generated master information with scanned data values associated with the test bills. Master information derived by one machine may be quickly and efficiently loaded into one or more other machines through a flash card loading system, thereby permitting the other machine(s) to evaluate authenticate test bills using master information obtained by the first machine. In one embodiment, the master information and characteristic data are normalized before denomination or authentication is performed to account for variations in individual machines.
