To withdraw cash from an automated teller machine (ATM), the client needs to do this by firstly selecting the cardless services function from the ATM’s screen. The client will then select withdraw money. The ATM will ask the client to enter the 4-digit PIN that was received via an SMS. If the PIN is not correct, the client will be notified and as them to re-enter the correct PIN. If the PIN is correct, the ATM will then ask the client to enter the amount they wish to withdraw. After entering the amount, the system will check if the amount requested is more less or equal to the balance. If the amount requested is greater than the balance, the ATM will inform the client and ask them to re-enter the correct amount. If the amount entered is less than or equal to the balance, the ATM will release the money and the system will update the balance. The client would be asked if they want the slip to be displayed or printed.
