What happens when the rule 'Block if CVC verification fails' is triggered?

When the rule 'Block if CVC verification fails' is triggered, the primary action that takes place is the blocking of the payment due to issues with the CVC code verification. This rule is designed to enhance security by ensuring that the cardholder possesses the physical card, which is corroborated by the CVC code. If the provided CVC does not match the records with the card issuer, it signifies a potential fraudulent transaction or misuse of the card.

As a result, the payment cannot proceed and gets blocked following the established security protocols. This approach helps to mitigate the risk of fraud and protects both merchants and consumers. By implementing this rule, payment processors can be more confident about the authenticity of a transaction, thereby maintaining the overall integrity of the payment system.
