Paper states a strategy for detecting doubtful transaction done using financial cards. Data Mining methods have been implemented to detect such doubtful transactions; existing methods produce incorrect results by categorizing the valid transaction as doubtful in some cases and creating misunderstanding and concern in customers faith. This effort is proposed to develop a fusion model using an existing technique Density-Based Spatial Clustering of Applications with Noise (DBSCAN) combined with a rule base algorithm to reinforce the accuracy of the existing technique. The DBSCAN algorithm combined with Rule base algorithm contribute a improved card fraud detection method with more precision over the existing DBSCAN algorithm when used alone.
