There are individual technologies that have been in place for some time, and they're reliable, and that's why we use them. There are other ones that are more recent. Some of the biometric stuff on the NEXUS card, for example, is more recent. We're trying to have a consistent approach with that and harmonizing with the United States, where we're both using the same technology, so it's very clear and consistent. I have had no indication there's an issue with the technology. Obviously there will be refreshes as they go through. There's always a life cycle to these things, and we account for that in the plan. I've heard no concerns about anything not being up to snuff.
