Not all e-commerce websites use 3D Secure. Online retailers decide whether or not to sign up for 3D Secure.

Goal:

To reduce fraudulent use of credit cards on the Internet by introducing additional security for online purchases.

How to activate it?

1. You have an S-Net account:

Log in to S-Net or S-Net Mobile, go to “Settings – Credit cards – 3D Secure” and follow the on-screen instructions. You can then instantly use your credit cards on e-commerce sites offering 3D Secure.

2. You don’t have an S-Net account:

Go to www.3dsecure.lu and follow the instructions.

You will receive a letter containing an activation code in a few days’ time, which you can use to finalise the activation procedure.

How does it work?

When you use your credit card to make a purchase on a 3D Secure site, a separate screen will pop up displaying your “personal message”. You will then be able to validate the payment by entering the single-use code delivered to the medium of your choice:

• your LuxTrust Token
• your mobile

You can only register one LuxTrust Token and one mobile number (Luxembourg or international) for each card.
