Abstract: A cash management system includes a cloud server, a banknote cash unit and a verification center. The banknote cash unit senses serial numbers of banknotes introduced therein for obtaining serial number data corresponding to the banknotes. The banknote cash unit further uploads the serial number data to the cloud server, such that the verification center downloads the serial number data. The verification center senses the banknotes sent thereto for obtaining the verification data corresponding to the banknotes sent to the verification center and determines whether the serial number data matches the verification data. Accordingly, the cash management system is able to verify all of banknotes delivered from backyard area to verification headquarter at one time.
