And that isn't something that we will consider because we must not fall into the trap of magical thinking. I have here a biometric identification card. If we had geosurveillance, I could have left this at the office and you would have thought I was at the office all afternoon when I was here. So establishing security measures does not involve magical thinking. It's very important to point that out.
I heard a comment to the effect that geosurveillance would solve all our problems. But no, it won't solve all our problems. What I can tell you about this biometric card—and we often compare ourselves to other countries—is that in our case, it's not a dream, it's becoming a reality. By December 31st, all of our employees in the country's main airports will have this card. In other countries, tens of millions of dollars are being invested and they're still at the pilot project stage. So I think we should be given some credit for what has been accomplished.
In terms of the technological details, Mr. McGarr could provide you with more information.
