Developed to improve the security of online payments, Verified by Visa and MasterCard SecureCode (3D Secure) offers customers the opportunity to validate their payment using secure PIN. If your card is registered for 3D Secure, you will need to enter your code in the pop up screen provided by your bank or credit card provider. If your card is not registered, Wordsworth & Black will omit this stage in the check out procedure. For further enquiries, please refer to our Terms of Sale.
