Description
Automated Teller Machine (ATM)
On an automated teller machine (ATM), the customer is identified by inserting a plastic ATM card with a magnetic stripe or a plastic smart card with a chip that contains a unique card number and some security information such as an expiration date or card verification value code (CVVC). When using an ATM on networked banks, customers can access their personal or business bank accounts in order to make cash withdrawals and check their account balances. For this assignment, consider cash withdrawal transactions from your favorite ATM machine.
Write a four to five (4-5) page paper in which you:
- Delimit the ATM problem by creating a problem diagram using Visio or an equivalent such as Dia. The diagram must show system components that are relevant to the problem of withdrawing cash. Note: The graphically depicted solution is not included in the required page length.
- Write one (1) paragraph that describes the use and meaning of the problem diagram components.
- Create two (2) Structured Analysis and Design Technique (SADT) diagrams to document the activities and data involved in the transactions stated above using Visio or an equivalent such as Dia. Note: The graphically depicted solution is not included in the required page length.
- Write one (1) paragraph that describes the use and meaning of the SADT diagram components.
- Provide three (3) possible scenarios of interaction between you and the ATM through a few message sequence charts.
- Create one (1) UML diagram for each scenario, from Question 5, to show the interactions. Note: The graphically depicted solution is not included in the required page length.
- Create one (1) state machine diagram for the ATM that covers the scenarios you have identified in Question 5 using Visio or an equivalent such as Dia. Note: The graphically depicted solution is not included in the required page length.
- Write one (1) paragraph that describes the use and meaning of the state machine diagram components.
- Use at least three (3) quality resources in this assignment. Note: Wikipedia and similar Websites do not qualify as quality resources.

transaction, online deposits or transaction holding, and money withdraws process. An automated
Teller Machine is a computer-based telecommunication device that facilitates the way the
financial institutions provides customers with a financial method that suit their needs. The
financial institutions use an Automated Teller Machines that are available in the public places
and does not require a human clerk or a bank employee to provide the transaction service to the
customers (Natarajan, 2001). ATMs are effective in that they serve the needs of the customers
anywhere, anytime, and the customer uses them at their convenient time. At an ATM, a customer
uses a plastic ATM card that consists of the unique numbers. A customer is identified by the
numbers available in the card because the security is administered by the customers’ personal
identification number (PIN). Automated Teller Machines allow customers to access bank
accounts to either make deposits, check balances as well as make cash withdraws. There are
various challenges associated with the Automated Teller Machines of which some are common
in the withdraw process.
Automated Teller machines are associated with fraudulent activities. A fraud activity is
the one that involves the use of other person’s credentials such as ATM card and PIN. Criminals
commit this type of crime by withdrawing the huge sums of money without the owner’s consent
(Sharma, 2004). Nonetheless, there are those criminals who ...
