Currency discriminator and authenticator having the capability of having its sensing characteristics remotely altered

摘要

A document handling system communicates with a host system such as a cash settlement machine. The operator of the host system enters the denomination of the notes to be counted by the note counting device. The host system then sends a signal to the document handling device to establish the denomination that is to be counted. The sensitivity level within the document handling device is set corresponding to the signal sent by the host. The document handling device then generates authenticity data from each of the plurality of notes and compares the authenticity data to the sensitivity level to determine whether each of the plurality of notes is genuine.
