Query: A Survey of Online Card Payment Fraud Detection using Data Mining-based
  Methods   Card payment fraud is a serious problem, and a roadblock for an optimally
functioning digital economy, with cards (Debits and Credit) being the most
popular digital payment method across the globe. Despite the occurrence of
fraud could be relatively rare, the impact of fraud could be significant,
especially on the cardholder. In the research, there have been many attempts to
develop methods of detecting potentially fraudulent transactions based on data
mining techniques, predominantly exploiting the developments in the space of
machine learning over the last decade. This survey proposes a taxonomy based on
a review of existing research attempts and experiments, which mainly elaborates
the approaches taken by researchers to incorporate the (i) business impact of
fraud (and fraud detection) into their work , (ii) the feature engineering
techniques that focus on cardholder behavioural profiling to separate
fraudulent activities happening with the same card, and (iii) the adaptive
efforts taken to address the changing nature of fraud. Further, there will be a
comparative performance evaluation of classification algorithms used and
efforts of addressing class imbalance problem. Forty-five peer-reviewed papers
published in the domain of card fraud detection between 2009 and 2020 were
intensively reviewed to develop this paper.
