Website Modification Reference

This section describes how to modify your website to integrate Payer Authentication services into your checkout process. It also provides links to payment card company websites where you can download the appropriate logos.

Website Modification Checklist

Modify web page buttons:

Order submission button: Disable the final “buy” button until the customer completes all payment and authentication requirements.

Browser back button: Plan for unexpected customer behavior. Check throughout the authentication process so you do not authenticate transactions twice. Avoid confusing messages, such as warnings about expired pages.

Add appropriate logos:

Download the appropriate logos of the cards that you support. Place these logos next to the card information entry fields on your checkout pages. For more information about obtaining logos and using them, see EMV 3-D Secure Services Logos.

Add informational message:

Add a message next to the final “buy” button and the card logo to inform your customers that they might be prompted to provide their authentication password. For examples of messages you can use, see Informational Message Examples.
