ATM

---

Description

The ATM application is a convenient and intuitive interface for interacting with an ATM. Developed using C# and the .NET Framework platform. The application provides users with a wide range of banking operations, including balance inquiry, account replenishment, cash withdrawal, phone number top-up, transferring funds to another card, and card termination. The intuitive user interface, created using Windows Forms, makes the interaction process simple and secure. Thus, users can efficiently utilize the banking services provided by this application while enjoying its high level of security.

PIN: 1111

Key Features

ATM and Language Selection

Upon application launch, users can select the desired ATM from the list of available options and set their preferred interface language (Russian, English, Ukrainian), ensuring a personalized user experience.

Card Interaction

The process of starting work with the ATM begins with inserting the card into the device. This stage is executed through an intuitively understandable method of dragging the card into the ATM slot, simplifying and speeding up the process. After inserting the card, the initialization of the process occurs, displayed through a progress indicator ProgressBar, which shows the progress of card recognition and PIN entry.

Operation Initialization

To track the progress of PIN entry and card recognition, the application uses a progress indicator (ProgressBar), providing users with visual feedback on the current state of the process.

PIN Code Security

User data security is ensured by setting limitations on PIN code entry. Users are provided with three attempts for correct entry. Upon exceeding the limit, the card is blocked, protecting against unauthorized access.

Card Operations

Users have the ability to perform a wide range of card operations, including balance inquiry, account replenishment, cash withdrawal, phone number top-up, fund transfer to another card, and card termination. This ensures maximum flexibility and convenience in using the application.

User-Friendly Interface

By using Windows Forms elements such as PictureBox, TextBox, Button, ProgressBar, MaskedTextBox, Label, and Timer, the application provides an attractive and intuitive interface, facilitating comfortable and efficient user interaction. Additionally, to enhance convenience, the interface supports the selection of application and ATM language immediately upon launch.

Used Technologies

The application is developed in the C# programming language, which provides powerful tools for creating high-quality applications.

The .NET Framework and .NET Core platforms were used for application development and operation, ensuring flexibility and compatibility with various operating systems.

Windows Forms was chosen as the platform for creating the graphical interface of the application, providing an intuitive and appealing user experience.

Limitations and Settings

To ensure ease of use and security of the application, various limitations and settings were programmatically established. For example, the application form is centered on the screen, making its location convenient for the user. Additionally, resizing of the form is prohibited to prevent accidental changes to the application's appearance and dragging forms is also prohibited.

For security purposes, the minimize, maximize, and close buttons of the form are hidden to prevent accidental application closure by the user. Restrictions on image sizes are also set to guarantee their proper display in the interface.

An important aspect of security is the restriction of accessibility to the PIN code entry field, making it impossible for unauthorized users to modify or interfere with it, thereby ensuring the protection of user data and privacy.
