Credit card fraud has become one of the growing problems. The Credit Card Fraud stands as major problem for worldwide financial institutions. It's crucial that credit card companies can classify fraudulent activities so that consumers don't have to pay for items they didn't agree to. With the making number of clients, credit card fakes are in addition reaching out at a comparative rate. The charge card data of a specific individual can be theft unlawfully and can be utilized unfairly.The credit card information of a particular individual can be robbery unlawfully and can be used wrongfully.. In this paper we have discussed different extortion location models which check if another transaction is fraudulent. Machine learning is widely regarded as one of the most effective methods for detecting fraud.

However there are number of challenges appear to tackle this problem, such as lack of publicly available data due to confidentiality reason,imbalanced class sizes,variant fraudulent behavior. To reduce imbalanced class sizes, we use smote sampling technique.In this work a comparison of five supervised machine learning algorithms :logistic regression, naive bayes, KNN ,Random Forest, Decision Tree to separate among certified and fraudulent transactions execution of the algorithms is assessed dependent on ordinarily acknowledged metric for example accuracy, precision and sensitivity.
