It's very clear that—don't hold me to the time here—shortly after the legislation was passed, the United States realized that the option of requiring everybody to have a passport was not practical. It doesn't lend itself to fast-reader technologies, with which you can put a card in front of a reader and swipe it, or whatever the technology would be.
It was more practical to have a new type of document. As I said earlier, it could have been a birth certificate, a driver's licence, or other forms of documentation that people readily have. Right now, it seems that people are looking at a new type of card, although there is still discussion in the United States about having an upgraded licence. That requires time because the states would have to produce the licence. It would have to have more capabilities than current licences, and it would have to be consistent across the country. So there are complications, but some people see it as the best way to go.
These are the options being reviewed, and hopefully we'll have a decision from Homeland Security and the State Department as to what the preferred option is. Then we can take it from there. As the legislation provides, it may well be a combination. So we still have some work to do, and they have some more work to do, before we see the conclusion.
