Over the past four decades the chargeback process has become more complex due to two principal factors. First, new reason codes have been introduced, old ones have been redefined, and deadlines have been changed. For bank employees, keeping up with the pace is tougher than ever. Second, new types of fraud have emerged. Fraudsters are more active and leveraging creative ways to avoid chargebacks. In spite of all this, the tools issuing banks have at their disposal to uncover fraud patterns have not matured in tandem. So, banks are left trying to apply what have become antiquated chargeback rules to this new reality. The result is massive inefficiency, if not failure.
