Case Study

An automated teller machine $($ATM$)$ is an electronic telecommunications device that enables customers of financial institutions to perform financial transactions, such as cash withdrawals, deposits, transfer funds, or obtaining account information, at any time and without the need for direct interaction with bank staff.

On most modern ATMs, customers are identified by inserting a plastic ATM card into the ATM, with authentication being by the customer entering a personal identification number $($PIN$)$ which must match the PIN stored in the chip on the card or in the issuing financial institution's database. ATM network has to be available $24$ hours a day. All the requirements are predefined and well understood.
