Why am I being asked to provide the card security code on my credit card when making a credit card payment online?
This is a security feature that provides increased protection against credit card fraud for both the customer and the merchant. This 3 or 4 digit code is often requested by merchants when a credit payment is being made over the internet when the credit card is not present. Card security codes are one way of making sure the purchaser has the credit card in their possession.
