3D Secure is a system that is used to verify a customer’s identity before an online purchase can be completed, if they have it activated on their card. With 3D Secure, customers are redirected to a page provided by their bank, where they are prompted to enter an additional password before their card can be charged.
Due to the customer possibly needing to answer a password, we are recommending that any payments £150+ should be taken by sending out the secure link over email, as opposed to manually over the phone. More Info Here
