Introduction

The development of use cases in systems analysis provides a foundational understanding of how users interact with systems and helps identify functional and non-functional requirements. In the context of banking systems, particularly ATM services, use cases play a pivotal role in ensuring seamless, secure, and user-friendly operations. This paper explores specific use cases related to ATM withdrawal, deposit, and transfer functionalities, illustrating their dependencies, and discusses associated ethical issues, supported by academic research.

Use Case of ATM Withdrawal

The ATM withdrawal use case begins with the customer inserting their bank card into the ATM. The system prompts the user to enter their Personal Identification Number (PIN). Upon correct entry, the system authenticates the user against the bank database. Once verified, the user is prompted to select "Withdrawal" and specify the amount. The system then verifies if sufficient funds are available in the customer's account. If funds are sufficient, the system dispenses cash and updates the account balance accordingly. The transaction concludes with a receipt option and the system returning the card.

Alternate courses include scenarios where the customer enters an incorrect PIN, leading to account lockout after multiple failed attempts, or when the requested withdrawal exceeds available funds, prompting an error message and transaction cancellation.

This use case ensures secure access, accurate transaction processing, and user-friendly interaction, vital for banking systems.

An illustration of this use case can be drafted using Visio, depicting actors, system states, and flow paths for typical and alternate courses.

Use Case Dependency for Making an Account Deposit

The deposit use case depends on the customer being authenticated through card insertion and PIN verification. Once authenticated, the user selects the "Deposit" option and inserts cash or checks into the ATM. The system then scans the deposit for validity, records the transaction, and updates the account balance. The deposit process may depend on network connectivity for real-time account updates and receipt printing. Dependencies include account authentication, transaction validation, and hardware interfaces for cash/check acceptance.

This use case illustrates the dependency structure with a diagram showing the sequence of authentication, deposit processing, and account updating, emphasizing system dependencies and data flow.

Use Case Dependency for Making an Account Transfer

The transfer use case builds upon initial authentication and requires the customer to specify the source and destination accounts, along with the transfer amount. This process depends on verifying available funds in the source account, authenticating both accounts if necessary, and updating the respective balances. The system's dependency includes secure data validation, transaction logging, and real-time account updates. The transfer process integrates dependencies such as authentication modules, account data access, and transaction management components, which must work cohesively to ensure data integrity and security.

Visio diagrams can be employed here to map dependencies, illustrating the interaction between user input, system validation, and database updates.

Ethical Issue in ATM Use Cases

An ethical issue pertinent to ATM use cases involves privacy and data security. Protecting customers' sensitive data, such as PINs and account information, is critical. System breaches or inadequate encryption could lead to identity theft or financial fraud. As ATM systems evolve to include biometric authentication and contactless transactions, ethical concerns about biometric data privacy and consent become prominent. Ensuring compliance with legal standards and respecting user privacy is essential in system design and implementation.

Research indicates that data breaches in financial services have severe repercussions for consumer trust and financial security (Nguyen et al., 2019). Ethical responsibilities extend to safeguarding user data, ensuring transparency in data use, and implementing robust security measures.

Conclusion

The detailed analysis of use cases related to ATM services highlights the importance of clear documentation, dependency management, and ethical considerations in designing banking systems. These use cases facilitate understanding user interactions and system requirements while emphasizing the need for secure, ethical practices. Future developments should focus on enhancing security protocols and ensuring compliance with legal and ethical standards, thereby fostering consumer trust and system reliability.
