CVV Validation Scenario Guide

Understanding CVV Validation

CVV validation is a crucial step in the credit card transaction process. It ensures that the person using the card is in possession of the physical card and is authorized to make purchases.

Step 1: Collect CVV Information

When a customer initiates a transaction, their credit card information, including the CVV, is collected. This information is then sent to the payment processor for verification.

Step 2: Verify CVV

The payment processor compares the CVV provided by the customer with the CVV on file with the issuing bank. If the numbers match, the transaction is likely to be authorized. If they do not match, the transaction is flagged for potential fraud.

Step 3: Transaction Approval

Once the CVV is verified, the transaction is processed. If there are no issues, the transaction is approved, and the funds are transferred. If the CVV is invalid, the transaction is denied.

Step 4: Handling Invalid CVV

In case of an invalid CVV, the system will notify the customer of the issue. The customer can then correct the CVV and try the transaction again. If the issue persists, further investigation may be required to prevent fraudulent activity.
