Understanding CVV Validation Process
When you make a purchase online, the CVV is one of the pieces of information that the merchant requests. This number helps to prevent unauthorized use of your card. The merchant verifies the CVV with the issuing bank to ensure that the transaction is legitimate.
Impact on Online Transactions
Invalid CVV entries can lead to transaction failures. If the CVV is incorrect, the bank will flag the transaction as potentially fraudulent, leading to a decline. However, a valid CVV also contributes to the smooth processing of online payments.
