The Visa Acquirer Monitoring Program (VAMP) is a new fraud program by Visa that replaces existing monitoring programs for disputes and fraud globally (excluding the LAC region).
The VAMP is designed to make online payments safer by incentivizing merchants and acquirers to keep their fraud and disputes below a ratio of their total settled transactions.
Note: Visa made a significant update to how they will calculate the program ratios, with corresponding increases to the thresholds at which these ratios will result in scheme fees.
