Why fitness sort
To sort currency according to different uses and fitness quality requirements. For example, ATM machines, bill changers and other self-service currency machines may require higher quality currency in order to operate properly, maximize machine uptime and minimize service calls. At the same time, currency designated for bank tellers, cashiers or similar customer service personnel may not have to be quite as clean, but should still meet certain quality standards to maintain a professional appearance, increase customer satisfaction and reduce transaction times.
To reduce cash transportation costs.
What is a fit versus an unfit note
In general, currency is considered fit, or suitable for recirculation if it meets all of the following requirements:
Is genuine (non-counterfeit) currency
Has proper dimensions
Is a current series design
Is free from excessive holes, tears, tape, or folded/missing corners
Has uniform brightness and is free from excessive soil and graffiti
Is free from excessive print wear
If one or more of these criteria is not met, a note can be classified as unfit and not suitable for further circulation. However, your own criteria for determining fit and unfit notes may differ based on your specific business needs.
