Card Testing Defense: What It Is

Key Strategies for Card Testing Defense
- Check for a magnetic strip or chip: Ensure the card has a magnetic strip or chip, which are common security features.
- Verify the card's expiration date: Look for the expiration date on the card to ensure it's still active.
- Check the card's CVV: The Card Verification Value (CVV) is a three-digit number on the back of the card, used for verification.
