Re: Implement CC mod or not?
If you intend taking what are called "off-line" payments, you need to make sure that your web server is PCI compliant, and that your bank (who will clear the payments) is okay with you accepting card details this way.
There's a million words already on this forum - just search PCI compliance to get an idea of what's involved.

Statistics show that the easier it is to pay the more sales you make - accepting Credit Cards is part of that. Your customers want to be able to buy in a safe "familiar" environment. To accept credit cards you need a merchant account and a gateway. You can easily use one of the built-in modules as soon as you get your merchant account set up.
