Meaning
Cryptographic security codes change for each transaction to prevent the reuse of stolen payment card information. Using dynamic card verification value replaces the static three-digit code found on the back of a physical card with a value generated by an algorithm. This numeric string is typically displayed on an integrated screen or generated within a mobile wallet application.
It validates that the cardholder is in possession of the original device or card at the moment of purchase.
Transaction Validation
Verification of the code occurs in real time at the issuing bank during the authorization request. Because the dynamic card verification value is valid for only a short period or a single use, a captured code cannot be used for subsequent fraudulent purchases. This mechanism is effective against card-not-present fraud and database breaches.
The algorithm synchronizes between the card and the bank server to ensure the values match.
Market Adoption
Issuers deploy this technology to reduce the costs associated with fraud. Payment networks encourage these standards to increase consumer confidence.
Implementation Cost
Deployment involves higher manufacturing expenses due to the need for a battery and a display on the card body. Software-based versions integrated into mobile apps avoid these physical costs but require a scalable backend infrastructure to manage the code generation. The total cost of ownership includes the initial hardware price and the ongoing maintenance of the authentication servers.
Banks weigh these expenses against the savings from reduced fraud losses.
