Your NAB card uses world-class security technology to help protect you from fraud and theft. We also monitor transactions to help minimise fraud.

Here are some ways you can play your part in keeping your debit, Visa debit and credit cards safe.

PIN, signatures and contact details

  • Sign your new card when it arrives.
  • Use the NAB app or NAB Internet Banking to activate your card and select a new PIN.
  • Destroy expired or unwanted cards properly by cutting through the signature and magnetic strip.
  • Never write down your PIN.
  • If you change your PIN, avoid choosing obvious numbers like your date of birth or the last four digits of your phone number.
  • Never give your credit card to anyone, even family or friends. If needed, you can apply for an additional card.
  • Make sure you keep your contact details up-to-date so we can contact you quickly if we detect suspicious transactions.
  • Use the NAB app or NAB Internet Banking to notify us before you travel overseas.

Using ATMs and EFTPOS

  • When making purchases, never lose sight of your card to reduce the chance of someone ‘skimming’ your details, i.e. using a device to copy the details from your card.
  • Look out for suspicious devices on ATMs or keypads.
  • Watch for people looking over your shoulder while using the ATM or key pad.
  • Cover the key pad when entering your PIN.
  • Keep your receipts and check them against your statement. If you don’t recognise a transaction, you can lodge a dispute.
  • Read and learn more about ATM security.

 

Shopping online

  • Only shop online at secure websites. Look for the padlock symbol before entering personal information.
  • Check the site you’re using is reputable. If you’re unsure about using the site, contact the merchant and ask about their security measures.
  • Ensure the computer you’re using has current anti-virus and firewall protection.
  • Print out online receipts to check against your statements.
  • Consider using Visa Secure which offers extra card security when you shop online at participating retailers for no additional cost.
