This project is an ATM simulator developed in Python, featuring a graphical interface built using the standard Tkinter library. It was created as a personal exercise to practice and demonstrate programming skills, persistent data handling, and interface design.
The simulator allows users to register, log in using a PIN, check their balance, make deposits and withdrawals, and view a transaction history.

Data persistence (
users.json)
Note: The files data/users.json and data/transactions.log are ignored in the repository for privacy and security reasons:
-
users.json stores sensitive user data (names, PINs, balances).
-
transactions.log contains detailed user transaction history.
Both files will be automatically created by the program if they do not exist. You can use the included data/users_example.json as a reference to understand the expected data structure.

This ATM simulator was created as a personal project to apply programming and interface development knowledge.
It was developed independently with a focus on structured logic, clean design and data persistence.
