TSYS risk team flagged an account recently (Little Clippers After School #84870018257971) for running 12 transactions against the same card after it was initially declined. TSYS would like us to prevent these type of transactions in case they are someone trying to use brut force technique to determine a dollar amount that will approve on fraudulent cards.
Enhancement would related to increased settings/control for fraud. This specifically could be addressed through velocity checks. May also want to look into excessive attempts to pay the same transaction or declines by a single profileID/accountID pair
