There are two options on how to accept credit card payments on your website: manual and automated.
MANUAL CREDIT CARD PROCESSING
What are the benefits?
There are few advantages of using manual credit card processing such as ability
to validate a suspicious order, remember if you processed a stolen credit card,
the bank will take the money back and will issue a chargeback fee (around $30).
Most of the suspicious orders would have incorrect telephone numbers and
addresses, so by processing a credit card manually, you have an ability to call
the customer to verify his telephone number, as well as his shipping address
via whereis.com.au. If you are still uncertain, you can always contact your
bank to validate the authenticy of the credit card. These things happen quite
rarely, but still happen.
There is no ability to validate a credit card manually when you use an
automated payment gateway, but there are other security mechanisms to prevent a
fraud like CVN (Credit Card Verification Number) Sometimes referred to CVC,
CVC2, CVV2 or CVV.
