Program Process

1. Insert Card

The card insertion process is simulated with time.sleep() method.

2. PIN Number

A bank API would be implemented in the future to verify password, but at this point of the project, 1234 is used as the PIN. The program terminates if user enters incorrect PIN more than 3 consecutive times, and the user would need to restart the login process by reinserting the card.

3. Select Account

The program asks user to pick one of the following account options:

• Checking Account
• Savings Account
• Finish Transaction

The account type is saved if either Checking Account or Savings Account is picked, and the program process continues. If Finish Transaction is picked, the program will terminate with a goodbye message.

4. See Balance/Deposit/Withdraw

With the selected account type, the program asks user for their transaction action:

• See Balance
• Deposit
• Withdraw
• Back to Select Account
• Finish Transaction

The transaction action will execute once the user picks an option.

Test Program

To run the program, enter the following in the root directory of the repository:

python3 atm_controller.py

As mentioned under Program Process (Step 2), 1234 is the temporary PIN for this project.
