What's the difference between application behavior for credit card payments made with a CVN or without a CVN?

Credit card payments made with required entry of a 3 or 4-digit Card Verification Number (CVN) necessitates the performance of two prerequisite setups. In the Setup and Maintenance work area, use the following: Offering: Financials, Functional Area: Customer Payments, Task: Manage Funds Capture Payment

Note: CVN capture during transaction authorization is currently not allowed. However, you may provide CVN during credit card token creation.

Credit card payments made without required entry of a CVN, follow the usual process where you create a transaction type of Invoice, submit the Create Automatic Receipts process, and an authorization is created during automatic receipt creation.
