Introduction

The CardEase 3DS Server is a hosted 3-D Secure Server (3DS Server) that allows for E-Commerce sites to accept and process Visa Secure, Mastercard Identity Check, Amex SafeKey 2.0 and Discover ProtectBuy 2.0 authentications.

The result of these authentications can then be used during the payment authorisation process providing conformance with card scheme rules and greater liability shift for the merchant.

There’s a lot more additional data able to be collected as a part of the EMV 3DS flow. Many of these fields are gathered during the Authenticate step.

Most of these fields are not considered mandatory, however you are encouraged to include as much data as possible.

By providing more data, the issuer has more to draw upon when deciding whether they need to initiate a challenge step up or to allow the authentication process to follow the frictionless flow. The CardEase 3DS Server makes use of the HTTP protocol using various methods (GET / POST) in order to perform cardholder authentication via the EMV 3DS 2.2 protocol.
