USER CREDIT CARD

what is the use of the option CC-credit card payment?

Does it do somehting?

I collect the creditnumber, expire date, name but not the security code: so I can not collect the money with a credit card gateway like OGONE (EUROPE) or other.
Please explain.

I've added a new field security_code to the user_card table. So far so good, the security_code is stored.

Still do not now what to do with this information.

BUT the confirmation mail send to customer is same as the one send to check: I only see one command to send this email, whatever order CHK or CC is placed.

How to change code that for CHK and CC is send a different Emailmessage
