Current credit card regulations do not allow us to store the Card Verification Value (CVV) codes with credit card information in our database.
If you want to capture the CVV code, you can use a payment gateway such as Authorize.NET®, Chase Paymentech™, or Intuit QuickBooks Merchant Service®. Alternatively, your customers can use PayPal® or PayPal Express®, where the credit card transaction is handled on PayPal's site.
