What is 3-D SECURE ?
We are working together with Visa and MasterCard to provide you with the latest in online security, giving you peace of mind when using your credit or debit card with us and you must now be 3-D Secure compliant (Also known as Verified by Visa or Mastercard Securecode). 3-D Secure works like Chip and PIN, except you choose a password instead of a 4-digit number. You can choose your password when you register for the service at the Checkout where you will be re-directed to your Card provider's secure website and registering takes less than a minute - it will work for all other online retailers in the future. THIS IS NOT YOUR BR SPECIAL TUNING ACCOUNT PASSWORD.
3-D Secure should not be confused with the Card Security Code which is a short numeric code that is printed on the rear of the card, which is still required for authorisation.
