Subject: ATM Simulator
Our client for this project has requested that we develop a machine that can simulate the functions of an automatic teller machine (ATM) such as one might find at any local bank. Your task is to design and build such a simulator using the components and materials of your choice. Here is a list of specifications that you can use as a guide in preparing your initial project proposal and technical plan:
• The simulator should be self-contained with no actual contact with the outside world.
• It should realistically simulate such features as user inquiry, prompting for password, type of transaction, and dollar amounts.
• The simulator should include its own set of entry keys or buttons, display device, printer, and dispenser for (simulated) money.
• The simulator should be triggered into operation by the insertion of an ATM-type bank card. The decoding and interpretation of information stored on the inserted cards is not a necessary feature of the system. An acceptable solution could instead involve storing passwords (possibly as an updateable list) inside the simulator; this list would be activated by the insertion of any card of the appropriate size.
We need at least 10 more requests to produce the solution.
