Self-service bill processing terminal and bill processing method thereof

The invention provides a self-service bill processing terminal and a bill processing method thereof. Execution information is input by an input module, and converted by a main control chip circuit into various execution instructions; a bill scanner scans a bill and displays the bill in a display module, the scanned bill falls into a bill temporary storage assembly to wait user validation on an operation component side, if the bill processing flow needs to be stopped, instruction information for taking out of the bill is input by the input module, the main control chip circuit commands a limiting device to execute the opening activity, the bill is taken out through a bill exit window, and the bill processing flow is stopped; if the bill in the bill temporary storage assembly is accurate, the main control chip circuit sends an opening instruction to a baffle, the baffle is opened, and under the gravity action, the bill falls into a bill storage platform for storage. The mechanism is simple and reliable. If it i
