Client Challenge
One of our customers, a rapidly growing regional bank, faced difficulties in managing their Automated Teller Machine (ATM) system’s transactions and user interactions. The previous system was rigid and lacked the necessary features to handle complex transaction logic, such as depositing, withdrawing, and monitoring user balances. The bank needed a comprehensive and intuitive system that would not only streamline operations but also provide an engaging user interface for the customers.
Our Solution
To meet this challenge, at BankTech Innovations, we developed a robust ATM system powered by Flask, SQLAlchemy, and PostgreSQL. The following are the core functionalities and solutions we implemented:
- User Management: We created a User model that handles customer information, including card numbers, PINs, and roles.
- Account Management: A comprehensive account management system allows customers to deposit, withdraw, and view balances seamlessly. This includes the implementation of constraints such as insufficient funds checks.
- Transaction Tracking: All transactions are tracked and stored in the database, providing complete transparency and accountability.
- Front-End Interaction: We designed an HTML interface that interacts with the back-end Flask application, providing users with real-time updates on their transactions and balances.
- Testing with Selenium: To ensure the integrity of the front-end interface, we implemented a series of tests using Selenium following the Page Object Model. This ensures that the UI shows the correct balance after every transaction.
- Database Integrity and Cascading Delete: With a well-structured relational database, deleting a user ID also removes all associated records in other tables, maintaining data integrity.
By implementing this multifaceted solution, our customer is now able to manage their ATM system with greater efficiency and provide an improved experience for their users. It’s a prime example of how custom software development can transform everyday challenges into streamlined operations.
