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.
