ATM Structure
The user interface of the available ATM system has the functions cardErrorMsg() and
PIN_ErrorMsg() those are being handled by the UserInetrface of the ATM system model.
The banking system is responsible for evaluating the PIN verification function in the system.
In this model, PIN verification is handled by the banking system. Considering the present
model, modification can be made through introducing Chip and PIN where the PIN security
verification can be delivered on the card itself. Since, the modification is adequate, it will
have very less impact on the overall model of the ATM system that can be demonstrated in
the following figure:
