Things you should know

  • 1 To take advantage of the NetLock security, CommBiz token holders must be identified. Identified CommBiz token holders are users that have had their identity verified by the Bank. New and existing users can be identified by going to the Admin tab in CommBiz, selecting the specific user and then selecting the ‘identification’ tab.

    2 NetLock devices are currently being provided free of charge for all CommBiz uers, however we reserve the right to charge this fee if you order the NetLock device but do not use the NetLock device.

    Your NetLock USB device should not be used as a data storage device as this will destroy its operation.

    The target market for these products will be found within the product’s Target Market Determination, available here.
