I would add that I absolutely agree with the points made thus far. The only addition I'd make is that I wouldn't take the notion that we are behind, that the solutions that have been developed and deployed around the world are typically one-off solutions, not globally interoperable.
Even the current state of global interoperability still has some work to do before we can be absolutely certain that a phone with a contactless card on it now is going to be accepted with the same service level quality that Canadians would expect when it's used in Malaysia or even the United States.
We've been testing the stuff for a number of years. Visa and Rogers together with one of our key clients, RBC, did a pilot a couple of years back whereby we were able to test for consumer response to the technology, what it would mean to provision card credentials onto a phone, security and such. It takes some time to get from those tests and working through those issues to something that can be produced on a production scale.
I echo the comment that we're absolutely at a tipping point for making this stuff happen, which is exciting.
