Verified by Visa

The 3D Secure technology is designed to reduce the possibility of fraudulent card use by authenticating the cardholder at the actual time of the transaction and subsequently protect him or her against unauthorised use of the card. Verified by Visa (VbV) authentication requires the cardholder to register their card on the card issuer’s website to take advantage of this service.
If you are registered, at the time of payment, a screen from your card issuer will prompt you to enter the unique personal code that you have registered with them. The card issuer then validates your personal code and approves the transaction.

If you are not registered, but the bank that issued your Visa card supports VbV, you may be prompted to enter your password or to sign up for VbV as you check out. You can also activate your current card now.
