Looking ahead, there is also more limited scope for fundamental innovation in the cash system compared with the scope for dynamic innovation in electronic payments. So this journey is in our national interest. 2. Functionality, Safety and Reliability I would now like to discuss three interrelated factors that will influence how quickly we undertake that journey.
These are: the functionality offered by the electronic system; the safety of that system, and the reliability of that system. The other factor that is also relevant is cost, and I will touch on this a little later. Functionality The rapid adoption of contactless payments in Australia shows that Australians change how they pay quite quickly when new functionality is offered.
