Credit Card Fraud Detection System Final Year Project Source Code

Credit Card Fraud Detection System is a Python Flask based final year project developed for detecting suspicious and fraudulent credit card transactions using rule-based risk scoring. This major project allows users to register, log in, reset passwords through security question and system-generated OTP, manage profiles, add transactions manually, upload transactions through CSV, validate transaction rows, check fraud for single or bulk transactions, view risk score, view reason tags, search/filter/sort records, download PDF or CSV reports, manage optional card profiles, view notifications, export user data, and clear personal transaction data. The system classifies each transaction as Safe, Suspicious, or Fraud based on risk factors such as unusual amount, odd transaction time, high-risk merchant, daily limit exceeded, and rapid transaction frequency. This Credit Card Fraud Detection source code is suitable for students who need a final year project, major project, minor project, source code, and project report based on Flask, SQLite, transaction analysis, and fraud detection logic.
