A system for wear and aging evaluation of a paper-based resource described herein is structured for determining a fitness state of a physical body structure of a paper resource item and for adaptive processing of the paper resource item in accordance with the fitness state. Specifically, the system comprises an item transfer unit configured to receive one or more paper resource items and a scanning device structured to retrieve a fitness state of a paper resource item from a physical state sensing component of the paper resource item. The system is structured to adaptively process the paper resource item based on determining whether (i) a wear level and (ii) an item age level of the paper resource item are associated with either a fit item type or an unfit item type.

A conveyance mechanism can convey bills to openings in two locations regarding at least one conveyance port of two conveyance ports of a determination unit. The conveyance mechanism can convey the bills between an acceptance unit and a plurality of cassettes through the determination unit. The conveyance mechanism can convey the bills from any cassette of the plurality of cassettes to other cassettes through the determination unit.

Provided are a quality control method for banknote identification and a quality control system for banknote identification. The quality control method for banknote identification includes: obtaining a multispectral signal collected by a contact image sensor (CIS); extracting a first eigenvalue of the multispectral signal; obtaining a corresponding second eigenvalue according to the first eigenvalue and a pre-set correction conversion value; and inputting the second eigenvalue into a banknote classifier to obtain a corresponding banknote classification result.
