Example Velocity Rules
Card Velocity Limit
Block if: Same card > 3 attempts in 1 hourWhy: Legitimate users rarely retry the same card 3+ times quickly. This catches card testing attacks.
IP Velocity Limit
Flag if: Same IP > 5 different cards in 10 minutesWhy: One person trying multiple cards = fraud. Real customers use 1-2 cards max.
Email Velocity Limit
Review if: Same email > $5,000 total in 24 hoursWhy: Catches stolen cards before they rack up huge losses. Adjust $ amount for your business.
⚠️ Pro Tip: Start with generous limits (3x your expected normal behavior) and tighten over time. Better to let a few fraudsters through than block your best customers.
