When it comes to card security, Commonwealth Bank is a leader in fraud protection. Our state of the art technology monitors your contactless transactions 24/7 against fraud. So if any unusual activity takes place, you’ll be alerted immediately. And if the unlikely happens and an unauthorised transaction occurs on your card, we’ll reimburse you 100%1.
However, these features also enhance security for added peace of mind:
- You don’t have to hand your card over at any time throughout the transaction.
- Your card must touch the contactless reader to work, so there's no risk of accidental payments.
- Even if your card accidentally touches the reader more than once, the transaction is only processed once.
If your CommBank credit or debit card is lost, stolen, or used without your authorisation, notify us as soon as possible, by calling 13 2221.
1 Provided you comply with the Credit Cards Conditions of Use if you have a credit card, and/or the Transactions, Savings and Investment Accounts Terms and Conditions if you have a debit card.
