VbV is a vital free service available to our Visa debit card holders providing extra protection when shopping on the internet. It works by asking you for a pre-registered password before your transaction is completed. This is designed to stop fraudulent use of your card and to make online shopping even more secure, as only you will know your personal password.
Even if you don't shop on the internet, in the wrong hands your card details could still be used to shop on the internet. Therefore, it is important that you register your card with VbV for additional security immediately.
