There are a number of countries that have very elaborate systems. I think I mentioned Mexico before. They have a 12-character alphanumeric card with a photo, thumb print, signature--everything is on the card, but it's the only document they have for 50% of the population. Brazil also has something that is very thorough.
We have never done a cost-benefit analysis because it has never been contemplated. If the committee wishes, I will undertake such a study to see how much it would cost. Remember, it's costing us about $6 million now just through databanks to do the updates from older vehicles, from the revenue files, and so on, which is very cheap for what we're achieving. But I think the cost would go up very significantly, to be honest with you, because I know how much it costs in Mexico to do this and maintain it. But it's entirely feasible.
