The Account Settings page (Figure 9) allows you to control the outcome of future transactions when certain security features fail, or are not present. CV2 refers to the last three digits on the back of debit and credit cards, for American Express cards it is the 4 digits on the front. AVS stands for Address Verification System. By default, the security settings are set to the strictest possible, if you need to relax any of the security settings this should only be done by you, the merchant.
