An ATM (Automatic Teller Machine) has been widely used in various commercial banks and for postal saving. The ATM operates in the 24-hour self-help manner, which brings people great convenience.
In an ATM automatic banknote adding system, all of cash recycling ATMs, cash deposit ATMs and banknote adding machines share a same kind of banknote boxes. The banknote box itself has an information memory for storing information on banknotes in the banknote box. Each banknote box has a physical ID number which is globally unique, so as to be able to distinguish from each other. The automatic banknote adding system may directly transmit a banknote box which is full of banknotes in a cash deposit ATM to a cash outputting ATM, and the cash outputting ATM automatically gets the information on the banknote in the banknote box, so as to automatically add banknotes. The banknote box may be changed at any moment at will between all banknote processing machines in the automatic banknote adding system, and information on each replacing banknote box is uploaded to a server of a bank through each ATM so as to record corresponding data, thus no man-made count is needed, so that the efficiency of processing banknote is greatly improved.
Presently, if an ATM is used for cash withdrawal, the ATM may send unqualified banknotes to a recovery part. However, information (including the number and face values of the banknotes) on the banknotes sent to the recovery part cannot be correctly determined. Therefore, it is impossible to accurately obtain the information on the residual banknotes in the banknote box.
For example, if a certain banknote is in an unqualified status such as an overlapped banknote or an adhesion banknote) when the banknote is output from a cash recycling ATM, it can be determined that the banknote is in the abnormal status by measuring the thickness or width, and thus the banknote is recovered. However, it is very difficult to determine the number of the recovered banknotes (taking the overlapped banknotes as an example, it is impossible to determine whether three or two banknotes are overlapped; and if there is adhesive substance on one banknote, the banknote may also be mistakenly determined as two banknotes). Therefore, it is unable to accurately track the information on the residual banknotes in the banknote box. To accurately obtain the information on banknotes in the banknote box is an important prerequisite for the ATM to automatically add banknotes.
