Secure online shopping

Verified by Visa and MasterCard SecureCode

To increase your card security when you shop online, register for the free services Verified by Visa or MasterCard SecureCode. Then when you shop with participating online stores you'll be protected with extra security.

  • Only shop online at secure websites - look for the padlock at the bottom of your screen before entering any personal information to ensure that you’re shopping from a secure site.
  • Look for reputable internet merchants or stores - anyone can set up a website, so if you are unsure of the business or their online security then ask for more information before you use their service.
  • Ensure the computer you use has current anti-virus and firewall protection.
  • Print out copies of online receipts to make it easier to check your statement.

Protecting your card

It's important to protect your credit card account from unauthorised transactions. Things you should do include:

  • sign your new card as soon as you receive it
  • never write down your PIN
  • if you change your PIN, avoid obvious numbers (eg. your date of birth or part of your phone number)
  • when you make purchases, never lose sight of your card
  • look for suspicious devices on ATMs or pinpads
  • when you enter your PIN, make sure no-one sees what you're doing
  • keep your receipts and check them against your statements
  • when your card expires, or if you don't want it any more, destroy it by cutting it in half through the signature and magnetic strip and any chip
  • never give your card to anyone, even family or friends.

Keep us up to date if you change your contact details, including your phone numbers and email address. This makes sure we can contact you quickly about suspicious transactions. You can read about changing your contact details on the Account changes page.

Extra security when you shop online

Verified by Visa is a free way to add an extra layer of security when you shop online with participating retailers.

If you already have a Visa card you can:

When you register you'll create a password and a "personal assurance message". When you shop online with a participating retailer you'll see your personal assurance message, which lets you know that your purchase will be verified by Visa.

Once you've seen your personal assurance message, enter your password. We check and confirm your password, and then your purchase can go ahead. Without your password, the store won't accept your Visa.

Additional cardholders can register for Verified by Visa separately, with their own password and personal assurance message.
