Automated teller machine and method therof

摘要

In an automated teller machine, a user interface unit transmits a user instruction to a main control unit (10). The main control unit generates control data according to the user instruction and an instruction from a host and transmits the control data to a cash input/output unit (50). A cash output control unit (50) in the cash input/output unit (50) withdraws cash from a safe based on the control data and outputs the cash. An encryption process unit (20) of the main control unit encrypts the control data. An encryption process unit (60) of the cash input/output unit (50) decrypts the encryption data encrypted by the encryption process unit (20) of the main control unit (10) and reproduces the original control data. Mutual authorization is performed between the main control unit (10) and cash input/output unit (50). <IMAGE>
