This new system involves a pin number/password that is not printed on the card in any way. The WorldPay screens forwards the customer to a Visa/Mastercard pin entry screen and the customer enters their confidential information that they have previously set up. Visa/MC return this back to WorldPay (or other processor) as accepted or failed. This way, WorldPay never find out this confidential information.
digitalghost, that is something different and has been used for most of the two years I have been taking card payments. This simply stops photocpied cards from being used.
