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.

Informational Message Examples
Add a brief message next to the final buy button on your checkout page to inform
customers that they might be prompted for their authentication password or to enroll in
the authentication program for their card.
These examples might be used, but consult your specific card authentication program to
make sure you conform to their messaging requirements.
Example
<card_type>
cards online, <your_business_name>

<card_authentication_program>
. When you submit your order, you might
receive a <card_authentication_program>
message from your
<card_type>
card issuer. If your card or issuer does not participate in
the program, you are returned to our secure checkout to complete your order. Please wait
while the transaction is processed. Do not click the Back
button
or close the browser window. Example
