What is Card Testing?
Card testing is a process where individuals attempt to test the validity of stolen credit card details by making small transactions. Velocity checks help in preventing such fraudulent activities.
Velocity Checks for Card Testing Fraud: Detection and Tuning
Understanding Velocity Checks
- Velocity checks monitor the speed and frequency of transactions made with a credit card.
- They identify any unusual patterns that could indicate fraudulent behavior.
- When a card exceeds the normal velocity limit, it triggers an alert for further investigation.
How Velocity Checks Prevent Card Testing
- By setting velocity limits, merchants can prevent multiple transactions in a short period of time, which is a common characteristic of card testing.
- These checks act as a first line of defense against potential fraud, reducing the risk of unauthorized access to card details.
- They also provide valuable data for analyzing and preventing future fraudulent attempts.
Importance of Velocity Checks
- Enhance security for both merchants and customers by reducing the likelihood of fraudulent transactions.
- Improve overall customer experience by reducing the incidence of false positives and false negatives.
- Help merchants comply with PCI DSS requirements, which include measures to prevent fraud.
