You can register the card in the service simply by making online purchases. If the site you are buying online is participating in the 3D Secure service and your BKT card is not registered in this service after you make Checkout as usual on the page, you will be automatically required to register the card in the service MasterCard SecureCode or Verified by Visa depending on your brand of your card.
Once the registration window appears, you must fill in the required information, your CIF number (the first 9 digits of the invoice to which the card relates), the card expiration date, CVV2 number (3-digit code in the back of the card) and the Mother’s maiden name. After filling in everything correctly, the next window prompts you to create a personal password that you will use in the future for online purchases.
You only need to do a card registration once.
