What is Credit Card Fraud Detection?

Credit Card Fraud Detection is the process of identifying unauthorized or suspicious transactions using historical transaction data and machine learning algorithms.

Each credit card transaction contains information such as transaction time, amount, and several transaction-related features. By learning patterns from historical data, a classification model can determine whether a new transaction is likely to be genuine or fraudulent.

Fraud detection systems are commonly used by:

  • Banks
  • Financial institutions
  • Payment gateways
  • E-commerce platforms
  • Digital wallet providers

The primary objective is to minimize financial losses by detecting fraudulent transactions while reducing false alarms for legitimate customers.
