Enable the CC module and it does exactly that, allows you to process CC on your local terminal.

You will need to configure it properly so it will e-mail you the middle set of numbers and store only the first and last group. Its a PITA to look in 2 different places for the numbers while hand keying them in but there is little to no security issues of having all the CC info stored on your server.

If you choose to have it all stored on your server I suggest that you delete it ASAP. Check with your processor, I believe they will soil their britches if they find out your are doing it this way and will most likely pull the plug on you it they catch wind of it.
