What is a CVV Velocity Check?
A CVV velocity check is a security measure used by merchants to monitor the rate at which cards are being used. It helps in identifying and preventing fraudulent activities by detecting unusually high transaction volumes within a short period.
Why Are CVV Velocity Checks Important?
- Prevent Carding Attacks: High transaction volumes can indicate a carding attack, where stolen card information is used for illegal purchases.
- Protect Merchants: By implementing CVV velocity checks, merchants can protect themselves from financial losses due to fraud.
- Enhance Customer Trust: Secure transactions lead to increased customer trust and confidence in the shopping experience.
How CVV Velocity Checks Work
- Transaction Monitoring: Merchants monitor the volume and frequency of transactions made with a specific card.
- Threshold Setting: Merchants set thresholds for what they consider normal transaction activity.
- Action Upon Exceeding Limits: If the transaction rate exceeds the set limits, merchants can take action, such as temporarily blocking the card or contacting the card issuer.
