The Visa Acquirer Monitoring Program (VAMP) comes into effect on April 1, 2025.
For the first three months of the program, Visa provides a grace period before assessing fines. Visa also provides a three-month grace period for first-time identifications within a rolling 12-month period.
Fraud and dispute thresholds under the VAMP will decrease from January 1, 2026.
