That's a big question.
One of the areas someone mentioned is government. I participated in the payment task force, including the digital ID. There's an area that is fascinating and very interesting. There were some questions and worries about security and privacy. A mobile phone where you can carry your digital ID allows you to do all sorts of things. It allows you to have higher degrees of privacy.
Today it is perfectly normal to go to a liquor store and, to prove your age, hand over a card that has your address on it, a photo of you, the type of driver's licence you have, your height—information that is irrelevant to what a liquor control board of a particular province needs. So you can now manage the degree of information that is passed, rather than handing over a generic card. There are also enormous cost savings in providing remote services to government agencies, for example.
The cost of health care is a massive problem in this country, provincially, right? Health professionals would like to be able to support users of the system remotely, but you have to be able to validate that the person on the computer is the person in question. If we can hold government ID in a phone securely, and you're online getting the results of your brain scan, the government agency will be able to know that the person on the other side of the phone who presented the government-issued health card from, say, the province of B.C., is actually that person and now can provide that brain scan result back to the user without worrying that it's being given to the wrong person. You can't put that back in the box—there's no zero liability for, oops, giving a brain scan result to the wrong person.
The task force, the digital ID group, is basically saying they like the distribution model being created for global payment methods. They'll adopt it and embrace it, because it's good enough for global payments, and it's good for regional government providers.
I could go on, given what I do, but....
