  • What is chargeback fraud?

    Chargeback fraud (also called “friendly fraud”) is the process of claiming refunds for illegitimate reasons. The fraudster initiates the chargeback process with the bank by filing false complaints and authorization complaints online with stolen cards and bank accounts. Without proper chargeback prevention, fraud can cost companies a fortune in the long run and undermine reputations with payment partners.

    Chargeback prevention is a set of verification measures made to thoroughly screen the cardholder and their bank card before a transaction can be made, which can be performed with verification software tools. The purpose is to prevent illegitimate transactions made with stolen bank cards and chargeback disputes altogether.

  • How do you fight chargeback fraud?

    Chargeback fraud and illegitimate refunds can be prevented with proper bank card credibility analysis and user verification prior to a transaction.
