What is 3D Secure?
3D Secure is a system of accepting credit and debit card payments on your website and receiving independent verification from the card issuer that the card being used is valid and authorised to make the transaction. This is achieved by the card holder setting up a password with the card issuer which is entered during the payment transaction on the card issuers own website. It is called 3D Secure because there are three parties involved in the transaction: the party taking the payment, the party making the payment and the card issuer. 3D Secure is often called 'Chip and Pin for the Internet'. It is based on the same principles but the underlying technology is very different.
