In the context of card verification, what does "not processed" indicate?

In the context of card verification, when a transaction status is labeled as "not processed," it specifically indicates that the CVV2 (Card Verification Value 2) was illegible. This status typically arises when the security code on the back of the card cannot be read or is not properly entered, preventing the transaction from moving forward in the authorization process.

This status is crucial because the CVV2 serves as an additional layer of security, helping to confirm that the person making the transaction has the physical card in their possession. If the CVV2 cannot be verified due to legibility issues, the transaction is marked as "not processed," highlighting the need for accurate card details to complete the verification process successfully. In contrast, other options like transaction approvals, insufficient funds, or a rejection of authorization involve different aspects of transaction status or cardholder account conditions.
