National ID Cards for Illegal Immigration?

Some in Congress are advocating a national id card - justifying it by saying its necessary to combat illegal immigration.

There is a simple, minimal, and elegant alternative to national ID cards.

This uses the simplicity pattern of "rewarding correct behavior rather than creating bureaucracy to catch and punish".

In other words, instead of creating a national id card to catch illegals, reward the first illegal from each company who turns himself in:

1. Require all employers to post a notice in English and Spanish where workers can see it saying that the first illegal employee to turn in his/her employer gets a green card.

2. Any employers caught employing illegal aliens will get fined a % of quarterly revenue. This will automatically scale the fine to mean something for companies like Walmart.

3. If, as I suspect, it is found that employers really need the labor, then create a guest worker program that does not lead to citizenship. Have a certain size pool of worker passes, hand them out on a first come/first serve basis at the border (as long as they pass a finger print check for a criminal background). If they leave the country to visit home, they have 30 days to reclaim their guest worker pass, or else it goes back into the pool.
