Learn about transaction signing

NAB Connect has a ‘Transaction Signing Limit’ by payment service. This means that the last Authorising User to authorise a payment has additional security steps to perform with their security token when a payment is equal to or over the Transaction Signing Limit.

Used correctly, this capability can reduce your exposure to fraud by imposing these additional payment verifications. This process generates a one-time password that is unique to the payment being authorised. To amend the default limit the below form would need to be completed and returned.

Remember that NAB will never call you and ask you to share any one-time passcodes to process a payment on your behalf.
