Why Are They Important?
Velocity checks help detect fraudulent activities early. If a card is being used excessively quickly, it may raise red flags for unauthorized use.
How to Perform Velocity Checks
1. Track Transaction Frequency: Monitor the number of transactions a card makes within a certain time frame. An unusually high frequency could indicate suspicious activity.
2. Examine Transaction Amounts: Look for large transactions that exceed the cardholder's usual spending limits. These could indicate fraud.
