NZ Bank Account Number Generator

Introduction​

Objective​

The goal is to develop an application that generates valid New Zealand bank account numbers. This project aims to reinforce programming skills by applying essential concepts to create a tool that produces numbers adhering to the specific format and validation rules of NZ bank account numbers.

Project Scope​

This project involves creating a generator capable of producing bank account numbers that comply with New Zealand's banking standards. It includes applying programming concepts for beginners to intermediate learners and allows flexibility in programming languages. The development of a user interface is optional and can range from command-line interfaces to graphical user interfaces.

Learning Objectives​

  • Understand and apply essential programming concepts including variables, conditionals, loops, functions, and handling user input/output.
  • Implement complex validation algorithms.
  • Optionally, explore user interface design for generator interaction.
  • Practice debugging and testing to ensure the generator outputs valid account numbers.

Implementation Requirements​

Core Functionality​

  • Bank Account Number Format and Validation Rules: Implement logic that adheres to the official New Zealand bank account structure and validation rules:
    • Account numbers are in the format: Bank number-Branch number-Account number-Suffix.
    • Implement validation using appropriate checksum algorithms as per New Zealand banking standards.
  • Generator Logic: Develop logic to randomly generate numbers fitting the NZ bank account format and passing all validation checks.

Examples of NZ Bank Account Numbers​

To guide the implementation, here are examples of the New Zealand bank account format (Note: These are illustrative and not to be used for actual transactions):

  • 01-902-0068389-00
  • 12-3140-0059489-000
  • 26-2600-0320871-032

User Interface Design (Optional)​

  • Optionally, create an interface that allows users to:
    • Initiate the generation of a new bank account number.
    • View the generated bank account number compliant with NZ banking standards.
  • The interface can range from a command-line to a basic GUI, depending on preferences and the programming language used.

Practice Exercises​

  • Exercise 1: Write the function to generate a random sequence that aligns with the structure of NZ bank account numbers, referring to the examples provided.
  • Exercise 2: Implement the validation algorithm to ensure generated numbers are valid according to NZ banking checksum rules.
  • Exercise 3: Optionally, include a feature to allow users to verify the validity of a given NZ bank account number.
  • Challenge: For those looking for a deeper dive, develop a graphical user interface for the application.

Tools and Environment​

  • Select a programming language that matches your learning goals and the project's requirements.
  • Use appropriate development tools and environments, such as IDEs, text editors, and debugging tools suitable for your chosen language.

Testing Strategy​

  • Perform unit testing on the generator logic to ensure it produces valid bank account numbers.
  • Test the validation algorithm to ensure it accurately assesses the validity of both generated and user-provided account numbers.
  • If a user interface is developed, conduct usability testing to ensure it provides a clear and intuitive experience.

Documentation Process​

  • Code Documentation: Thoroughly comment your code to explain the functionality and logic of key sections.
  • Reflective Documentation: Document your development process, noting any challenges encountered, solutions devised, and ideas for future project improvements.
  • User Guide: If applicable, provide clear instructions for setting up and using the application.

Evaluation and Refinement​

Upon completing the project, take time to review your work, identifying areas for improvement, additional features, or optimization opportunities.

Sharing and Community Engagement​

Share your completed project for feedback, engage in code reviews, and participate in discussions within relevant programming communities.
