Abstract: This disclosure describes systems, methods, and computer-readable media related to detecting fraud in retail return transactions. In some embodiments, one or more parameters associated with a retail transaction may be received by at least one server comprising one or more computer processors. The server may evaluate the one or more risk factor conditions associated with the one or more parameters. The risk factor conditions may be indicative of a fraudulent return transaction. The server may generate one or more risk scores associated with the retail transaction based at least in part on the evaluating of the one or more risk factor conditions.
