Abstract:
1. A money item acceptor comprising: a signal source to produce a money item parameter signal as a function of a sensed characteristic of a money item, a store to provide data corresponding to a normal acceptance range of values of the parameter signal for a money item of a particular denomination, having high and low acceptance probability regions, wherein the value of the parameter signal corresponds to a high or low probability of an occurrence of a sensed money item of said particular denomination, and a processor configuration operable to control a gate for directing money items towards an accept path or a reject path, the processor configuration further configured to determine when an occurrence of the parameter signal corresponding to the first money item falls within the normal acceptance range and within the low acceptance probability region of the normal acceptance range, and to provide an output to the gate to direct the first money item towards the accept path, to determine when an occurrence of the parameter signal corresponding to the first money item falls outside of an internal security range of values within the high acceptance probability region and within the normal acceptance range, and to provide an output to the gate to direct the first money item towards the accept path, said processor configuration being further configured to determine when an occurrence of the parameter signal corresponding to the first money item falls within the internal security range of values within said high acceptance probability region of the normal acceptance range, and to provide an output to the gate to direct the first money item towards the accept path, and
