Executable
(See below for directions)
To run the simulation above, you need to do the following:
- Click on the "ON" button (lower right-hand corner) to turn the ATM on.
- Enter the number of $20 bills you want to have be in the cash dispenser at the
start of the simulation when you are prompted to do so, and press RETURN
- Perform any number of sessions, as follows:
- Click on the "Click to insert card" button to simulate inserting a card
- Type in the card number when you are prompted to do so (see below), and press
RETURN
- Enter the PIN associated with the card (see below). Although you can use
your regular keyboard, it's more fun to click on the keys on the simulated ATM
keyboard as displayed.
- Perform any number of transactions, using your mouse to click the keys on the simulated ATM
keyboard. Note that the machine will simulate ejecting your card when you indicate
you do not wish to perform any more transactions (unless, of course, your card is
retained due to too many invalid PINs).
- Turn off the ATM by clicking on the "OFF" button (same position as the "ON"
button". Note that you cannot turn the ATM off while in the middle of a customer
session.
- The entire simulation may be repeated as many times as you want, by turning
the machine ON again.
For demonstration purposes, this program uses a very simple simulation of the bank, with
hardwired card numbers and PIN's, etc. The following are the available cards:
Card Number | PIN |
Available accounts |
1 | 42 | Checking account #1, Savings account #2 |
2 | 1234 | Checking account #1, Money market account #3 |
| |
(Note that both cards link to the same checking account) |
All the features of the bank work - both current and available balances (initially
the same) are maintained for each account and a $300 daily withdrawal limit per card
is enforced.
I would appreciate feedback about the
operation and/or appearance of this applet
on different platforms. (Feedback about other issues is welcome, too, of course.)
